+# Windows 环境安装指南
+
+## 🚨 重要提醒
+在 Windows 系统上运行网络抓包功能，需要安装 **Npcap** 库。
+
+## 📥 安装步骤
+
+### 1. 下载 Npcap
+- 访问官网：https://npcap.com/
+- 点击 "Download" 下载最新版本
+- 选择 "Npcap x.xx installer for Windows" 
+
+### 2. 安装 Npcap
+1. **以管理员身份运行**安装程序
+2. 在安装选项中，**必须勾选**：
+   - ✅ "Install Npcap in WinPcap API-compatible mode"
+   - ✅ "Support raw 802.11 traffic"（可选）
+3. 点击 "Install" 完成安装
+4. 重启计算机（推荐）
+
+### 3. 启动应用程序
+1. **以管理员身份运行**命令行或IDE
+2. 启动 Spring Boot 应用：
+   ```bash
+   mvn spring-boot:run
+   ```
+3. 访问 http://localhost:8080 验证功能
+
+## ⚠️ 常见问题
+
+### 问题1：Native library not found
+**原因**：未安装 Npcap 或安装不完整
+**解决**：重新安装 Npcap，确保勾选 WinPcap 兼容模式
+
+### 问题2：No network interfaces found  
+**原因**：权限不足
+**解决**：以管理员权限运行应用程序
+
+### 问题3：Access denied
+**原因**：Windows 防火墙阻止
+**解决**：
+1. 临时关闭防火墙测试
+2. 或添加 Java 程序到防火墙例外
+
+## 🔧 验证安装
+
+启动应用后，查看控制台日志：
+- ✅ "WinPcap/Npcap 本地库加载成功"  
+- ✅ "找到 X 个网络接口"
+
+如果看到错误信息，请按上述步骤重新安装 Npcap。

+
+## 📖 使用指南
+
+### 1. 创建补丁类
+
+#### Spring Bean 补丁示例
+```java
+@HotPatch(
+    type = PatchType.SPRING_BEAN,
+    originalBean = "userService",
+    version = "1.0.1",
+    description = "修复getUserInfo空指针异常"
+)
+@Service
+public class UserServicePatch {
+    public String getUserInfo(Long userId) {
+        if (userId == null) {
+            return "未知用户"; // 修复空指针问题
+        }
+        // ... 其他逻辑
+    }
+}
+```
+
+#### 静态方法补丁示例
+```java
+@HotPatch(
+    type = PatchType.STATIC_METHOD,
+    originalClass = "com.example.utils.MathHelper",
+    methodName = "divide",
+    version = "1.0.3",
+    description = "修复除零异常"
+)
+public class MathHelperDividePatch {
+    public static int divide(int a, int b) {
+        if (b == 0) {
+            throw new IllegalArgumentException("除数不能为零");
+        }
+        return a / b;
+    }
+}
+```
+
+### 2. 打包补丁
+```bash
+# 编译补丁类
+javac -cp "target/classes:lib/*" patches/UserServicePatch.java
+
+# 打包为jar
+jar cf UserService-1.0.1.jar -C target/classes patches/UserServicePatch.class
+
+# 放到补丁目录
+cp UserService-1.0.1.jar ./patches/
+```
+
+### 3. 加载补丁
+
+#### 通过Web界面
+1. 打开 http://localhost:8080/index.html
+2. 选择补丁包
+3. 点击"加载补丁"按钮
+
+#### 通过API
+```bash
+curl -X POST "http://localhost:8080/api/hotpatch/load" \
+     -d "patchName=UserService&version=1.0.1"
+```
+
+### 4. 测试补丁效果
+
+访问测试接口验证补丁是否生效：
+```bash
+# 测试用户服务
+curl "http://localhost:8080/api/test/user"
+
+```
+
+## 🔧 配置说明
+
+### application.properties
+```properties
+# 热补丁配置
+hotpatch.enabled=true
+hotpatch.path=./patches
+
+
+### JVM 启动参数
+```bash
+-javaagent:target/springboot-hot-patch-agent.jar
+-XX:+UnlockDiagnosticVMOptions
+-XX:+DebugNonSafepoints
+```

+# 补丁打包脚本示例
+
+本目录包含了如何将补丁类打包为JAR文件的示例脚本。
+
+## 打包Spring Bean补丁
+
+```bash
+#!/bin/bash
+
+# 设置变量
+PATCH_NAME="UserService"
+VERSION="1.0.1"
+PATCH_CLASS="com.example.hotpatch.patches.UserServicePatch"
+
+# 编译补丁类
+echo "编译补丁类: $PATCH_CLASS"
+# windows
+javac  -encoding UTF-8 -cp "target/classes;target/lib/*" -d temp src/main/java/com/example/hotpatch/patches/UserServicePatch.java
+# linux
+javac  -encoding UTF-8 -cp "target/classes:target/lib/*" -d temp src/main/java/com/example/hotpatch/patches/UserServicePatch.java
+
+# 打包为JAR
+echo "打包补丁: $PATCH_NAME-$VERSION.jar"
+jar cf $PATCH_NAME-$VERSION.jar -C ./temp .
+
+# 清理临时文件
+rm -rf ./temp
+
+echo "✅ 补丁打包完成: $PATCH_NAME-$VERSION.jar"
+```
+
+## 批量打包所有补丁
+
+```bash
+#!/bin/bash
+
+PATCHES_DIR="../src/main/java/com/example/hotpatch/patches"
+OUTPUT_DIR="."
+
+# 创建临时目录
+mkdir -p temp
+
+# 编译所有补丁类
+echo "编译所有补丁类..."
+javac -cp "../target/classes:../target/lib/*" \
+      -d ./temp \
+      $PATCHES_DIR/*.java
+
+# 为每个补丁类创建单独的JAR
+for patch_file in $PATCHES_DIR/*.java; do
+    filename=$(basename "$patch_file" .java)
+    
+    # 提取版本信息（从注解中）
+    version=$(grep -o 'version = "[^"]*"' "$patch_file" | sed 's/version = "//;s/"//')
+    if [ -z "$version" ]; then
+        version="1.0.0"
+    fi
+    
+    # 创建补丁JAR
+    patch_name=$(echo $filename | sed 's/Patch$//')
+    jar_name="$patch_name-$version.jar"
+    
+    echo "打包补丁: $jar_name"
+    jar cf $jar_name -C ./temp com/example/hotpatch/patches/$filename.class
+done
+
+# 清理
+rm -rf temp
+
+echo "✅ 所有补丁打包完成"
+```

+# Spring Boot 在线调试工具
+
+基于 Java Agent + ByteBuddy 的运行时调试注入工具，支持在不重启应用的情况下动态注入调试日志。
+
+
+## 📦 快速开始
+
+### 1. 构建项目
+
+```bash
+cd springboot-online-debug
+mvn clean package
+```
+
+### 2. 启动应用
+
+```bash
+# 方式1：使用 javaagent 启动
+java -javaagent:target/springboot-online-debug-1.0.0.jar -jar target/springboot-online-debug-1.0.0.jar
+
+# 方式2：启动后动态 attach（需要配置 JVM 参数）
+java -jar target/springboot-online-debug-1.0.0.jar
+```
+
+### 3. 访问管理界面
+
+打开浏览器访问：http://localhost:8080/index.html
+
+## 🎯 使用示例
+
+### 精确方法调试
+
+```bash
+# 通过 REST API 添加调试规则
+curl -X POST http://localhost:8080/api/debug/method \
+  -H "Content-Type: application/json" \
+  -d '{"target": "com.example.onlinedebug.demo.UserService.getUserById"}'
+```
+
+### 类级别调试
+
+```bash
+# 调试整个类的所有方法
+curl -X POST http://localhost:8080/api/debug/class \
+  -H "Content-Type: application/json" \
+  -d '{"target": "com.example.onlinedebug.demo.UserService"}'
+```
+
+### 包级别调试
+
+```bash
+# 调试整个包下的所有类
+curl -X POST http://localhost:8080/api/debug/package \
+  -H "Content-Type: application/json" \
+  -d '{"target": "com.example.onlinedebug.demo"}'
+```
+
+### 正则模式调试
+
+```bash
+# 使用正则表达式匹配方法
+curl -X POST http://localhost:8080/api/debug/pattern \
+  -H "Content-Type: application/json" \
+  -d '{"target": ".*Service.*\\.get.*"}'
+```
+
+## 📊 调试输出示例
+
+当调试规则激活后，控制台会输出详细的调试信息：
+
+```
+[DEBUG-INJECT] com.example.onlinedebug.demo.UserService.getUserById() called with args: Long@123
+[DEBUG-INJECT] com.example.onlinedebug.demo.UserService.getUserById() completed in 45ms returning: User@{id=123, name=...}
+```
+
+
+## ⚠️ 注意事项
+
+1. **性能影响**：
+   - 只有激活的调试规则才会产生性能开销
+   - 避免在生产环境开启全局调试
+   - 建议在排查完问题后及时清理调试规则
+
+2. **安全考虑**：
+   - 调试工具会暴露内部数据，请在安全环境中使用
+   - 生产环境使用时建议启用认证机制
+   - 避免调试包含敏感信息的方法

+# Spring Boot API 监控面板
+
+## 项目简介
+基于 Spring Boot 3 实现的轻量级 API 性能监控面板，采用**分级采样**策略，支持时间段筛选和接口名搜索功能。
+
+## 技术实现
+
+### 分级采样策略
+```
+├── 秒级桶 (最近5分钟)   - 300个桶，精确到秒
+├── 分钟级桶 (最近1小时)  - 60个桶，分钟聚合  
+├── 小时级桶 (最近24小时) - 24个桶，小时聚合
+└── 天级桶 (最近7天)     - 7个桶，天聚合
+```
+
+## 技术栈
+- **后端**: Spring Boot 3.2.1 + Spring AOP + Lombok
+- **前端**: 纯 HTML + TailwindCSS + Alpine.js
+- **Java 版本**: 17+
+
+## 快速开始
+
+### 1. 编译运行
+```bash
+cd springboot-api-dashboard
+mvn clean install
+mvn spring-boot:run
+```
+
+### 2. 访问界面
+- 监控面板: http://localhost:8080/index.html
+- API 接口: http://localhost:8080/api/metrics
+
+### 3. 测试接口
+项目内置了演示接口用于测试：
+- `GET /api/demo/hello` - 简单接口
+- `GET /api/demo/users` - 用户列表
+- `POST /api/demo/users` - 创建用户（模拟偶尔失败）
+- `GET /api/demo/products?limit=10` - 商品列表
+- `GET /api/demo/orders/{orderId}` - 订单查询
+- `GET /api/demo/slow` - 慢接口（2-5秒）
+- `GET /api/demo/error` - 错误接口（50%失败率）
+
+## API 接口文档
+
+### 获取监控指标（支持筛选）
+```
+GET /api/metrics?startTime=1640995200000&endTime=1641000000000&methodFilter=user
+```
+**参数：**
+- `startTime` - 开始时间戳（毫秒）
+- `endTime` - 结束时间戳（毫秒）
+- `methodFilter` - 接口名过滤关键字
+
+### 获取汇总统计（支持筛选）
+```
+GET /api/metrics/summary?startTime=1640995200000&endTime=1641000000000&methodFilter=user
+```
+
+### 快捷时间查询
+```
+GET /api/metrics/recent/5?methodFilter=demo    # 最近5分钟
+GET /api/metrics/recent/60?methodFilter=user   # 最近1小时
+```
+
+### 清空所有指标
+```
+DELETE /api/metrics
+```
+
+### 清理过期指标
+```
+DELETE /api/metrics/stale?maxAgeMs=3600000
+```
+
+## 界面功能详解
+
+### 时间范围筛选
+- **快捷按钮**: 5分钟、30分钟、1小时、6小时、24小时
+- **自定义时间**: 精确指定开始和结束时间
+- **智能桶选择**: 根据时间跨度自动选择最适合的数据粒度
+
+### 接口搜索
+- **实时搜索**: 输入关键字实时过滤接口
+- **模糊匹配**: 支持接口名模糊匹配
+- **搜索防抖**: 500ms防抖，避免频繁请求
+
+### 数据展示
+- **汇总卡片**: 监控接口数、总调用数、错误数、平均响应时间
+- **详细表格**: 每个接口的完整统计数据
+- **多维排序**: 支持按任意列排序
+- **成功率进度条**: 直观显示接口成功率
+
+## 使用场景
+- ✅ **性能分析** - 快速找到最慢的方法
+- ✅ **稳定性监控** - 发现失败次数多的接口  
+- ✅ **容量评估** - 统计高频调用方法，辅助扩容
+- ✅ **临时排障** - 替代复杂APM，用于中小规模应用
+- ✅ **趋势分析** - 通过时间筛选分析接口性能趋势
+- ✅ **问题定位** - 通过搜索快速定位特定接口问题
+
+## 注意事项
+- 监控数据存储在内存中，重启后会丢失
+- 适合单机部署，不支持集群数据聚合  
+- 内存占用固定，适合高并发生产环境
+- 数据精度在可接受范围内，适合APM监控场景

+          3. 使用spring-boot-starter-logging统一管理
+          4. 排除示例：
+             
+               org.slf4j
+               slf4j-simple
+             
+      
+      database-driver:
+        patterns:
+          - ".*mysql.*"
+          - ".*postgresql.*"
+          - ".*Driver.*"
+          - ".*jdbc.*"
+        severity: CRITICAL
+        advice: |
+          数据库驱动冲突。
+          当前冲突：${className}
+          版本：${versions}
+          
+          建议解决方案：
+          1. 统一数据库驱动版本
+          2. 检查是否同时引入了不同的驱动包
+          3. 排除旧版本驱动，保留最新版本
+          4. 使用Spring Boot管理的驱动版本
+      
+      jackson-json:
+        patterns:
+          - ".*jackson.*"
+        severity: MEDIUM
+        advice: |
+          Jackson JSON库冲突。
+          当前冲突类：${className}
+          冲突JAR包数量：${jarCount}
+          
+          建议解决方案：
+          1. 统一Jackson版本（建议使用Spring Boot管理的版本）
+          2. 排除第三方库中的jackson依赖
+          3. 使用spring-boot-starter-json
+          4. 在dependencyManagement中统一版本
+      
+      spring-framework:
+        patterns:
+          - ".*springframework.*"
+          - ".*spring-.*"
+        severity: HIGH
+        advice: |
+          Spring框架版本冲突。
+          当前版本：${versions}
+          涉及JAR：${jars}
+          
+          建议解决方案：
+          1. 使用Spring Boot的版本管理
+          2. 在dependencyManagement中统一Spring版本
+          3. 排除第三方库中的Spring依赖
+      
+      apache-commons:
+        patterns:
+          - ".*apache.*"
+          - ".*httpclient.*"
+          - ".*httpcore.*"
+        severity: MEDIUM
+        advice: |
+          Apache组件版本冲突。
+          冲突类：${className}
+          
+          建议解决方案：
+          1. 使用dependencyManagement统一版本
+          2. 排除传递依赖中的旧版本
+          3. 考虑迁移到Spring的替代方案
+

    Spring Boot 静态资源权限控制演示
    
+
+        
+
+        
    
+            
    测试说明
    
+            
    此演示项目包含三种静态资源权限控制方案：
    
+            
      
+                
    • 方案一：Spring Security 全局保护 - 默认配置，/uploads/ 下的资源需要登录才能访问
      • 
+                
    • 方案二：自定义Controller代理 - 通过 /files/ 端点访问私有文件，支持复杂权限控制
      • 
+                
    • 方案三：拦截器动态校验 - 使用拦截器对 /uploads/ 路径进行权限检查
      • 
+            
    
+        
    
+
+        
    
+            
    公开资源测试
    
+            
    以下资源无需登录即可访问：
    
+            
+        
    
+
+        
    
+            
    受保护资源测试
    
+            
    以下资源需要相应权限才能访问：
    
+
+            
    方案一测试（Spring Security 全局保护）
    
+            
+
+            
    方案二测试（Controller 代理访问）
    
+            
+
+            
    方案三测试（拦截器校验）
    
+            
    访问 /uploads/ 路径下的文件时，会被拦截器检查权限
    
+
+            
    受保护API测试
    
+            
+        
    
+
+        
    
+            
    请先登录
    
+            
    要测试受保护的资源，请先 登录。
    
+        
    
+
+        
    
+            
    测试账号
    
+            
      
+                
    • 管理员：用户名 admin，密码 admin123
      • 
+                
    • 普通用户：用户名 user，密码 user123
      •

+# Spring Boot 动态规则引擎 Demo
+
+## 项目简介
+
+这是一个基于 **Spring Boot + QLExpress** 的动态规则引擎演示项目，展示如何在不重启应用的情况下动态修改业务规则。项目采用前后端分离架构，使用 TailwindCSS 构建现代化的管理界面。
+
+## 🚀 核心功能
+
+- **动态规则管理** - 运行时加载、修改、删除业务规则
+- **前后端分离** - REST API + 现代化前端界面
+- **业务场景演示** - 完整的电商订单处理流程
+- **热更新支持** - 无需重启应用即可修改规则逻辑
+- **可视化管理** - 直观的规则管理和测试界面
+
+## 🎯 解决的痛点
+
+**传统方式的问题：**
+- 业务规则变更需要修改代码、重新编译、发布部署
+- 营销活动、风控策略等频繁变化的规则维护成本高
+- 无法快速响应业务需求变化
+
+**动态规则引擎的优势：**
+- ✅ 规则热更新，无需重启应用
+- ✅ 业务人员可直接配置规则
+- ✅ 快速响应营销活动需求
+- ✅ 降低运维成本和风险
+
+## 🛠 技术栈
+
+- **后端：** Spring Boot 3.2.0, QLExpress 3.3.1
+- **前端：** HTML5 + JavaScript + TailwindCSS
+
+## 📋 业务场景演示
+
+### 电商订单处理流程
+
+项目通过一个完整的电商订单处理场景，展示动态规则引擎的实际应用：
+
+1. **VIP折扣规则** - 根据用户等级应用不同折扣
+2. **满减活动规则** - 满足条件时自动减免金额
+3. **积分奖励规则** - 基于最终金额计算积分
+
+### 预置规则示例
+
+#### VIP折扣规则 (`vip_discount`)
+```javascript
+if (userLevel == "GOLD") {
+    return price * 0.8;
+} else if (userLevel == "SILVER") {
+    return price * 0.9;
+} else {
+    return price;
+}
+```
+
+#### 满减活动规则 (`full_reduction`)
+```javascript
+if (totalAmount >= 200) {
+    return totalAmount - 50;
+} else if (totalAmount >= 100) {
+    return totalAmount - 20;
+} else {
+    return totalAmount;
+}
+```
+
+#### 积分奖励规则 (`points_reward`)
+```javascript
+return Math.round(totalAmount * 0.1);
+```
+
+## 🚀 快速开始
+
+### 1. 启动应用
+```bash
+git clone 
+cd springboot-dynamic-rule
+mvn spring-boot:run
+```
+
+### 2. 访问应用
+- **规则管理页面：** http://localhost:8080/index.html
+- **业务演示页面：** http://localhost:8080/business.html
+
+### 3. 体验功能
+1. 在规则管理页面查看和测试规则
+2. 在业务演示页面模拟订单处理
+3. 动态修改规则并观察业务逻辑变化
+
+## 📡 API 接口
+
+### 规则管理 API
+```bash
+GET    /api/rules                 # 获取所有规则
+POST   /api/rules                 # 添加新规则
+PUT    /api/rules/{ruleName}      # 更新规则
+DELETE /api/rules/{ruleName}      # 删除规则
+POST   /api/rules/execute/{name}  # 执行规则
+```
+
+### 业务演示 API
+```bash
+POST /api/orders/simulate?userLevel={level}&amount={amount}  # 模拟订单处理
+POST /api/orders/process     # 处理订单
+```
+
+### 示例请求
+```bash
+# 执行VIP折扣规则
+curl -X POST http://localhost:8080/api/rules/execute/vip_discount \
+  -H "Content-Type: application/json" \
+  -d '{"userLevel": "GOLD", "price": 100}'
+
+# 模拟订单处理
+curl -X POST "http://localhost:8080/api/orders/simulate?userLevel=GOLD&amount=150"
+```

+                    
    
+                        电商订单处理流程： 当用户下单时，系统需要依次执行多个业务规则来计算最终价格和积分奖励。
+                        通过动态规则引擎，我们可以在不重启应用的情况下调整这些业务逻辑。
+

+# 许可证控制系统
+
+基于RSA2048的Spring Boot许可证控制系统，支持Windows和Linux主板序列号绑定。
+
+## 功能特性
+
+- ✅ RSA2048公私钥签名验签
+- ✅ 主板序列号硬件绑定（Windows/Linux）
+- ✅ 许可证有效期控制
+- ✅ 功能权限管理
+- ✅ Web演示界面（前后端分离）
+- ✅ REST API接口
+
+## 快速开始
+
+### 1. 环境要求
+
+- Java 17+
+- Maven 3.6+
+- Windows或Linux操作系统
+
+### 2. 启动应用
+
+```bash
+# 编译项目
+mvn clean package
+
+# 启动应用
+mvn spring-boot:run
+
+# 或者直接运行jar包
+java -jar target/springboot-lic-1.0.0.jar
+```
+
+### 3. 访问演示界面
+
+打开浏览器访问：`http://localhost:8080`
+
+## API接口
+
+### 密钥管理
+
+- `POST /api/keys/generate` - 生成新密钥对
+- `POST /api/keys/load` - 加载密钥
+- `GET /api/keys/status` - 检查密钥状态
+
+### 许可证操作
+
+- `POST /api/license/generate` - 生成许可证
+- `POST /api/license/verify` - 验证许可证
+
+### 硬件信息
+
+- `GET /api/hardware/info` - 获取硬件信息
+
+## 使用说明
+
+### 1. 生成密钥对
+
+首先在Web界面点击"生成新密钥对"按钮，系统会自动生成RSA2048密钥对。
+
+### 2. 创建许可证
+
+填写许可证信息：
+- 软件名称
+- 授权给（公司名称）
+- 到期时间
+- 功能权限（逗号分隔）
+
+点击"生成许可证"即可创建签名的许可证文件。
+
+### 3. 验证许可证
+
+将许可证JSON内容粘贴到验证区域，点击"验证许可证"进行验证。
+
+系统会检查：
+- 签名有效性
+- 硬件指纹匹配
+- 有效期
+
+## 项目结构
+
+```
+src/main/java/com/license/
+├── controller/     # REST控制器
+├── entity/         # 实体类
+├── service/        # 业务服务
+├── util/           # 工具类
+└── config/         # 配置类
+
+src/main/resources/
+├── static/         # 前端静态文件
+└── application.yml # 应用配置
+```
+
+## 技术栈
+
+- **后端**: Spring Boot 3.x, Java Security API
+- **前端**: HTML, JavaScript, TailwindCSS
+- **加密**: RSA2048, SHA256withRSA
+- **序列化**: Jackson JSON
+
+## 注意事项
+
+1. **密钥安全**: 私钥应妥善保管，不要泄露
+2. **硬件绑定**: 更换主板后需要重新生成许可证
+3. **生产环境**: 建议将密钥存储在安全的密钥管理系统中
+4. **Linux权限**: Linux下获取硬件信息可能需要sudo权限
+
+## 许可证格式
+
+```json
+{
+  "subject": "MyApp",
+  "issuedTo": "Company Name",
+  "hardwareId": "MOTHERBOARD_SERIAL",
+  "expireAt": "2025-12-31",
+  "features": ["BASIC", "EXPORT", "REPORT"],
+  "signature": "Base64_Signature"
+}
+```

+# Shamir Secret Sharing - 五门三限密钥共享系统
+
+基于 Shamir Secret Sharing (SSS) 算法的门限密钥共享演示系统，实现了"五门三限"的经典案例：将密钥拆分为 5 份，任意 3 份即可恢复。
+
+## 项目特点
+
+- ✅ **纯 Java 实现** - 基于拉格朗日插值和有限域运算，无需第三方算法库
+- ✅ **前后端分离** - Spring Boot RESTful API + HTML/JS/TailwindCSS
+- ✅ **交互友好** - 现代化 UI 设计，支持一键复制、实时验证
+- ✅ **演示性强** - 内存存储（Map），适合学习和演示使用
+
+⚠️ **注意**：本项目使用 `ConcurrentHashMap` 存储会话信息，仅用于演示。生产环境应使用数据库或分布式存储（如 Redis、MySQL）。
+
+## 技术栈
+
+### 后端
+- Spring Boot 3.2.0
+- Java 17
+- Maven
+- Lombok
+
+### 前端
+- HTML5
+- TailwindCSS 3.x（通过 CDN）
+- Vanilla JavaScript
+
+## 快速开始
+
+### 1. 克隆项目
+```bash
+cd springboot-shamir
+```
+
+### 2. 构建并运行
+```bash
+# 使用 Maven 构建
+mvn clean package
+
+# 运行 Spring Boot 应用
+mvn spring-boot:run
+
+# 或者直接运行 JAR
+java -jar target/springboot-shamir-1.0.0.jar
+```
+
+### 3. 访问前端
+打开浏览器访问：http://localhost:8080
+
+## API 接口
+
+### 1. 拆分密钥
+**POST** `/api/shamir/split`
+
+请求体：
+```json
+{
+  "secret": "my-super-secret-key",
+  "totalShares": 5,
+  "threshold": 3
+}
+```
+
+响应：
+```json
+{
+  "sessionId": "uuid-xxx",
+  "shares": [
+    "1:a1b2c3d4...",
+    "2:e5f6g7h8...",
+    "3:i9j0k1l2...",
+    "4:m3n4o5p6...",
+    "5:q7r8s9t0..."
+  ],
+  "message": "密钥已拆分为 5 份，任意 3 份可恢复原始密钥"
+}
+```
+
+### 2. 恢复密钥
+**POST** `/api/shamir/combine`
+
+请求体：
+```json
+{
+  "shares": [
+    "1:a1b2c3d4...",
+    "3:i9j0k1l2...",
+    "5:q7r8s9t0..."
+  ]
+}
+```
+
+响应：
+```json
+{
+  "secret": "my-super-secret-key",
+  "message": "成功使用 3 个份额恢复密钥",
+  "success": true
+}
+```
+
+### 3. 健康检查
+**GET** `/api/shamir/health`
+
+响应：`Shamir Secret Sharing Service is running`
+
+## 算法原理
+
+### Shamir Secret Sharing (SSS)
+
+基于**拉格朗日插值定理**：
+- 构造 t-1 次多项式：f(x) = a₀ + a₁x + a₂x² + ... + a_{t-1}x^{t-1}
+- 其中 a₀ = secret（密钥）
+- 生成 n 个点：(x₁, f(x₁)), (x₂, f(x₂)), ..., (xₙ, f(xₙ))
+- 恢复时用拉格朗日公式计算 f(0) = a₀
+
+### 数学保证
+- 任意 t 个点可唯一确定多项式
+- 少于 t 个点则有无穷多个可能的多项式
+- 因此少于 t 份无法推导出密钥
+
+## 应用场景
+
+1. **金融安全** - 银行大额转账多人审批
+2. **区块链多签** - 数字货币钱包多重签名
+3. **云密钥管理** - 云服务商与用户共同持有密钥碎片
+4. **企业权限控制** - 高危操作需多人参与
+5. **数据备份** - 分布式密钥存储，防止单点故障

    🔐 Shamir 门限密钥共享系统
    
+            
    基于拉格朗日插值的五门三限算法演示

    💡 什么是五门三限？
    
+            
    
+                五门三限是门限密码学的经典应用：将一个密钥拆分为 5 份密钥碎片，
+                任意 3 份即可恢复原始密钥，少于 3 份则完全无法推算。
+            
    
+            
    
+                ⚠️ 注意：本演示使用内存 Map 存储，实际生产环境应存储到数据库或分布式存储系统。

+                
    
+                    
    数学基础
    
+                    
    
+                        基于 Shamir Secret Sharing (SSS)，利用拉格朗日插值和有限域运算

+                
    
+                
    
+                    
    安全性保证
    
+                    
    
+                        任何少于门限值的份额组合，数学上完全无法推导出原始密钥
+

+# ABAC 权限管理系统
+
+基于 **JCasbin** 的属性访问控制（ABAC）演示项目，实现业务逻辑与权限逻辑的完全解耦。
+
+## 🚀 快速开始
+
+### 1. 启动后端
+
+```bash
+cd springboot-permission
+mvn spring-boot:run
+```
+
+### 2. 访问前端
+
+打开浏览器访问：http://localhost:8080
+
+## 🎯 功能特性
+
+### ✅ 核心功能
+
+- **ABAC 权限模型**：基于用户和资源属性的动态授权
+- **AOP 切面拦截**：通过 `@CheckPermission` 注解实现无侵入式权限控制
+- **策略动态配置**：支持运行时添加/删除策略规则
+- **前后端分离**：HTML + Tailwind CSS + Axios
+
+### 📋 权限规则示例
+
+| 规则 | 主体条件 | 资源条件 | 操作 |
+|------|---------|---------|------|
+| 同部门可编辑 | `r.sub.dept == r.obj.dept && r.sub.id == r.obj.ownerId` | `true` | edit |
+| 同部门可读 | `r.sub.dept == r.obj.dept` | `true` | read |
+| 所有者可删除 | `r.sub.id == r.obj.ownerId` | `true` | delete |
+| 公开文档可读 | `true` | `r.obj.type == "public"` | read |
+
+## 🧪 测试场景
+
+### 场景 1：部门隔离
+- 张三（研发部）只能编辑研发部的文档
+- 李四（销售部）无法访问研发部文档
+
+### 场景 2：所有权控制
+- 文档创建者可以删除自己的文档
+- 其他用户无法删除
+
+### 场景 3：公开资源
+- 所有用户都可以阅读 `type=public` 的文档
+
+## 🔧 技术栈
+
+- **后端**：Spring Boot 3.2.0 + JCasbin 1.55.0
+- **前端**：HTML + Tailwind CSS + Axios
+- **权限引擎**：JCasbin（支持 RBAC/ABAC/RBAC with domains）
+
+## 📝 使用说明
+
+### 1. 在业务代码中使用权限注解
+
+```java
+@CheckPermission(action = "edit")
+@PutMapping("/{id}")
+public Result update(@PathVariable String id, @RequestBody Document doc) {
+    return Result.success(documentService.update(doc));
+}
+```
+
+### 2. 策略配置
+
+**模型文件（model.conf）**：
+```
+[request_definition]
+r = sub, obj, act
+
+[policy_definition]
+p = sub_rule, obj_rule, act
+
+[matchers]
+m = eval(p.sub_rule) && eval(p.obj_rule) && r.act == p.act
+```
+
+**策略文件（policy.csv）**：
+```
+p, r.sub.dept == r.obj.dept, r.sub.id == r.obj.ownerId, edit
+p, r.sub.dept == r.obj.dept, true, read
+```

+# Spring Boot 对象审计
+
+极简版对象审计示例，使用 Spring Boot 3 与 Javers 在内存中记录实体变更，并通过 REST API 暴露。前端页面使用纯 HTML + Tailwind CSS，通过 Fetch API 调用接口，界面与提示均为中文。
+
+## 后端
+
+- 技术栈：Java 17、Spring Boot 3、Spring Web、Javers Core。
+- 数据存储：`ConcurrentHashMap` 保存商品与审计日志，进程重启后数据会清空。
+- 审计逻辑：拦截商品的新增、更新、删除操作，将 `javers.compare` 的 Diff JSON 直接写入审计流。
+- 主要接口（前缀 `/api/products`）：
+  - `GET /api/products` - 查询全部商品。
+  - `GET /api/products/{id}` - 根据编号获取商品。
+  - `PUT /api/products/{id}` - 新建或更新商品（可携带 `X-User` 头作为操作人）。
+  - `DELETE /api/products/{id}` - 删除商品。
+  - `GET /api/products/{id}/audits` - 查看指定商品的审计记录。
+  - `GET /api/products/audits` - 查看全部审计记录。
+
+## 前端
+
+- 页面位置：`src/main/resources/static/index.html`（Spring Boot 会自动以静态资源目录提供服务）。
+- 访问地址：后端启动后打开 `http://localhost:8080/index.html`；也可以直接双击文件本地预览。
+- 功能说明：
+  1. 表单区用于创建或更新商品，可选填操作人。
+  2. 商品列表支持查看审计与删除操作。
+  3. 审计时间线支持筛选单个商品或回看全部记录，Diff JSON 会解析成中文说明。
+
+如需修改后端地址，请在页面顶部脚本中调整 `API_BASE` 常量。

+- ✅ **多版本密钥共存**: 新 Token 用新密钥，旧 Token 仍可验证
+- ✅ **用户无感知**: 密钥轮换不影响已登录用户
+- ✅ **KID 标识**: JWT Header 包含密钥 ID，支持多版本验证
+- ✅ **定时清理**: 自动清理过期的密钥
+
+### 演示功能
+- 🔐 **用户认证**: 登录/退出、Token 生成和验证
+- 🛡️ **受保护资源**: 需要有效 Token 才能访问
+- 🔑 **密钥管理**: 查看密钥状态、手动轮换、清理过期密钥
+- 🔍 **Token 解析**: 解析 JWT Header、Payload 和验证状态

+
+## 配置说明
+
+### application.yml
+
+```yaml
+# 双端口配置
+dual:
+  port:
+    user-port: 8082    # 用户端端口
+    admin-port: 8083   # 管理端端口
+
+# Spring配置
+spring:
+  application:
+    name: multi-port-application
+
+# 日志配置
+logging:
+  level:
+    com.example.multiport: DEBUG
+```
+
+## 核心技术
+
+- **双端口配置**: 通过`TomcatServletWebServerFactory`配置多个Connector
+- **API路由分离**: 使用自定义注解`@UserApi`和`@AdminApi`配合`WebMvcConfigurer`
+- **端口感知拦截器**: 根据请求端口执行不同的处理逻辑
+- **分端口日志**: 为不同端口使用独立的Logger实例
+- **健康检查**: 为每个端口提供独立的健康检查端点

+# 动态表单系统 - SpringBoot + JSON Schema
+
+## 🎯 项目简介
+
+这是一个基于 SpringBoot + JSON Schema 构建的动态表单验证系统，实现了"配置驱动开发"的理念。通过 JSON Schema 定义表单结构，系统自动生成前端表单界面和后端验证逻辑，大幅提升开发效率。
+
+## ✨ 核心特性
+
+- 🔧 **配置驱动**：只需定义 JSON Schema，自动生成完整表单系统
+- ✅ **统一验证**：前后端共享同一套验证逻辑，确保数据一致性
+
+## 🏗️ 技术架构
+
+### 后端技术栈
+- **SpringBoot 3.2.1** - 核心框架
+- **JSON Schema Validator** - Schema验证引擎
+- **Jackson** - JSON数据处理
+
+
+## 🚀 快速开始
+
+### 环境要求
+- Java 17+
+- Maven 3.6+
+
+### 启动步骤
+
+1. **克隆项目**
+```bash
+git clone 
+cd springboot-form
+```
+
+2. **编译运行**
+```bash
+mvn clean spring-boot:run
+```
+
+3. **访问应用**
+```
+浏览器打开: http://localhost:8080
+```
+
+## 📝 API接口
+
+### 表单管理
+
+| 方法 | 路径 | 说明 |
+|------|------|------|
+| GET | `/api/forms/schemas` | 获取所有可用表单 |
+| GET | `/api/forms/{schemaId}/config` | 获取表单配置 |
+| POST | `/api/forms/{schemaId}/submit` | 提交表单数据 |
+| POST | `/api/forms/{schemaId}/validate-field` | 实时字段验证 |
+| GET | `/api/forms/{schemaId}/submissions` | 获取表单提交数据 |
+| GET | `/api/forms/statistics` | 获取系统统计信息 |
+
+### 请求示例
+
+#### 获取表单配置
+```bash
+curl -X GET "http://localhost:8080/api/forms/user-registration/config"
+```
+
+#### 提交表单数据
+```bash
+curl -X POST "http://localhost:8080/api/forms/user-registration/submit" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "username": "testuser",
+    "email": "test@example.com",
+    "password": "Test123456",
+    "confirmPassword": "Test123456"
+  }'
+```
+
+## 🎨 预置表单
+
+系统预置了两个示例表单：
+
+### 1. 用户注册表单 (`user-registration`)
+- 基础信息：用户名、邮箱、密码
+- 个人信息：姓名、手机号、生日
+- 兴趣偏好：多选兴趣标签
+- 订阅设置：新闻通讯订阅
+
+### 2. 满意度调查表单 (`satisfaction-survey`)
+- 总体满意度评分
+- 服务体验评价
+- 推荐意愿
+- 详细反馈
+
+## 🔧 JSON Schema 示例
+
+```json
+{
+  "$schema": "https://json-schema.org/draft/2020-12/schema",
+  "type": "object",
+  "title": "用户注册表单",
+  "required": ["username", "email", "password"],
+  "properties": {
+    "username": {
+      "type": "string",
+      "title": "用户名",
+      "minLength": 3,
+      "maxLength": 20,
+      "pattern": "^[a-zA-Z0-9_]+$"
+    },
+    "email": {
+      "type": "string",
+      "title": "邮箱地址",
+      "format": "email"
+    },
+    "password": {
+      "type": "string",
+      "title": "密码",
+      "minLength": 8,
+      "pattern": "^(?=.*[a-z])(?=.*[A-Z])(?=.*\\d).{8,}$"
+    }
+  }
+}
+```

+# Spring Boot 时间轮
+
+这是一个基于Spring Boot的时间轮（Timing Wheel）实现项目，提供了完整的时间轮功能和可视化的监控界面。
+
+## 🚀 项目特性
+
+- ✅ **高效时间轮算法**：O(1)时间复杂度的任务调度
+- ✅ **前后端分离架构**：独立的前端页面，纯静态部署
+- ✅ **实时可视化监控**：动态时间轮图表、任务状态分布、性能统计
+- ✅ **完整的RESTful API**：支持任务的CRUD操作
+
+## 🚀 快速启动
+
+### 1. 启动后端服务
+
+```bash
+cd springboot-timingwheel
+mvn spring-boot:run -Dmaven.test.skip=true
+```
+
+后端服务将启动在：http://localhost:8080
+
+### 2. 访问前端页面
+
+直接打开 `http://localhost:8080/index.html` 文件即可访问监控页面。
+
+## 📊 功能特性
+
+### 时间轮核心功能
+- **高效调度**: O(1)时间复杂度的任务添加和删除
+- **批量处理**: 同一槽位的多个任务可以批量触发
+- **多层支持**: 理论支持多层时间轮处理不同精度需求
+
+### 监控界面功能
+- **实时统计**: 总任务数、已完成、失败、活跃任务数
+- **时间轮可视化**: 圆形时间轮实时动画展示
+- **任务管理**: 创建、取消、查看任务详情
+- **状态监控**: 任务状态分布饼图
+- **配置管理**: API地址配置、刷新间隔调整
+
+### API接口
+- `GET /api/timingwheel/stats` - 获取时间轮统计信息
+- `GET /api/timingwheel/execution-stats` - 获取执行统计
+- `GET /api/timingwheel/tasks` - 获取活跃任务列表
+- `POST /api/timingwheel/tasks/sample` - 创建示例任务
+- `POST /api/timingwheel/tasks/batch` - 批量创建任务
+- `DELETE /api/timingwheel/tasks/{taskId}` - 取消任务
+- `POST /api/timingwheel/cleanup` - 清理已完成任务
+
+## ⚙️ 配置说明
+
+### 后端配置 (application.yml)
+```yaml
+timingwheel:
+  config:
+    slot-size: 512              # 槽位数量
+    tick-duration: 100          # 时间间隔（毫秒）
+    worker-threads: 4           # 工作线程数
+    enable-multi-wheel: true    # 启用多层时间轮
+    enable-metrics: true        # 启用监控指标
+    task-timeout: 30000         # 任务超时时间（毫秒）
+```
+
+## 🎯 使用示例
+
+### 创建单个任务
+```javascript
+// 前端调用
+const result = await window.apiManager.createSampleTask('simple', 2000);
+
+// 后端API调用
+curl -X POST http://localhost:8080/api/timingwheel/tasks/sample \
+  -H "Content-Type: application/json" \
+  -d '{"type": "simple", "delay": 2000}'
+```
+
+### 批量创建任务
+```javascript
+// 前端调用
+const result = await window.apiManager.createBatchTasks(10, 1000, 5000);
+
+// 后端API调用
+curl -X POST http://localhost:8080/api/timingwheel/tasks/batch \
+  -H "Content-Type: application/json" \
+  -d '{"count": 10, "minDelay": 1000, "maxDelay": 5000}'
+```

+# Spring Boot 字段级加密演示项目
+
+## 🎯 项目概述
+
+这是一个基于 Spring Boot 3 + MyBatis 的字段级加解密演示项目，实现了**透明**的字段级加密功能。通过简单的 `@Encrypted` 注解，即可实现敏感数据的自动加密存储和解密读取。
+
+### ✨ 核心特性
+
+- 🔐 **透明加密**：业务代码零侵入，自动加解密
+- 🛡️ **安全算法**：使用 AES-GCM 加密算法，支持防篡改
+- 🚀 **零配置**：注解驱动，开箱即用
+- 🔧 **可扩展**：支持自定义加密算法和密钥管理
+
+## 🚀 快速开始
+
+### 1. 环境要求
+
+- JDK 17+
+- Maven 3.6+
+
+### 2. 运行项目
+
+```bash
+# 克隆项目
+git clone 
+cd springboot-column-encryption
+
+# 编译运行
+mvn spring-boot:run
+```
+
+### 3. 访问应用
+
+- **前端界面**：http://localhost:8080
+- **API接口**：http://localhost:8080/api/users
+- **H2控制台**：http://localhost:8080/h2-console
+  - JDBC URL: `jdbc:h2:mem:testdb`
+  - 用户名: `sa`
+  - 密码: `password`
+
+## 📖 使用指南
+
+### 基本用法
+
+1. **在实体类字段上添加注解**：
+
+```java
+@Data
+public class User {
+    private Long id;
+    private String username;
+
+    @Encrypted  // 添加此注解即可实现自动加密
+    private String phone;
+
+    @Encrypted
+    private String idCard;
+
+    // 普通字段不会加密
+    private Integer age;
+}
+```
+
+2. **正常使用 MyBatis 操作**：
+
+```java
+// 插入数据 - 自动加密敏感字段
+User user = new User();
+user.setUsername("张三");
+user.setPhone("13812345678");  // 会自动加密存储
+user.setIdCard("110101199001011234");  // 会自动加密存储
+userMapper.insert(user);
+
+// 查询数据 - 自动解密敏感字段
+User result = userMapper.findById(user.getId());
+System.out.println(result.getPhone());  // 输出: 13812345678 (已自动解密)
+```
+
+### 支持的加密字段
+
+- ✅ 手机号
+- ✅ 身份证号
+- ✅ 邮箱
+- ✅ 银行卡号
+- ✅ 家庭住址
+- ✅ 其他字符串类型敏感信息
+
+## 🔧 核心原理
+
+### 1. 注解机制
+
+```java
+@Target(ElementType.FIELD)
+@Retention(RetentionPolicy.RUNTIME)
+public @interface Encrypted {
+    Algorithm algorithm() default Algorithm.AES_GCM;
+    boolean searchable() default false;
+}
+```
+
+### 2. TypeHandler 自动处理
+
+```java
+@MappedJdbcTypes(JdbcType.VARCHAR)
+@MappedTypes(String.class)
+public class EncryptTypeHandler extends BaseTypeHandler {
+
+    @Override
+    public void setNonNullParameter(PreparedStatement ps, int i, String value, JdbcType jdbcType) {
+        // 写入数据库时自动加密
+        ps.setString(i, CryptoUtil.encrypt(value));
+    }
+
+    @Override
+    public String getNullableResult(ResultSet rs, String columnName) {
+        // 从数据库读取时自动解密
+        return CryptoUtil.decrypt(rs.getString(columnName));
+    }
+}
+```
+
+### 3. 自动注册机制
+
+通过 `ObjectWrapperFactory` 自动识别标记了 `@Encrypted` 注解的字段，并注册相应的 TypeHandler。
+
+## 🔐 安全特性
+
+### 加密算法
+- **算法名称**：AES-GCM
+- **密钥长度**：256位
+- **IV长度**：12字节（随机生成）
+- **认证标签**：128位
+
+### 密钥管理
+```java
+// 默认密钥（生产环境请使用安全的密钥管理系统）
+String secretKey = "MySecretKey12345MySecretKey12345";
+
+// 支持运行时更新密钥
+CryptoUtil.updateKey(newSecretKey);
+
+// 生成随机密钥
+String randomKey = CryptoUtil.generateRandomKey();
+```
+
+## 📊 API 接口
+
+### 用户管理接口
+
+| 方法 | 路径 | 描述 |
+|------|------|------|
+| GET | `/api/users` | 获取所有用户 |
+| GET | `/api/users/{id}` | 获取用户详情 |
+| POST | `/api/users` | 创建用户 |
+| PUT | `/api/users/{id}` | 更新用户 |
+| DELETE | `/api/users/{id}` | 删除用户 |
+| GET | `/api/users/search` | 搜索用户 |
+| GET | `/api/users/stats` | 获取统计信息 |
+
+### 请求示例
+
+```json
+POST /api/users
+{
+    "username": "张三",
+    "phone": "13812345678",
+    "idCard": "110101199001011234",
+    "email": "zhangsan@example.com",
+    "bankCard": "6222021234567890123",
+    "address": "北京市朝阳区建国路88号",
+    "age": 34,
+    "gender": "男",
+    "occupation": "软件工程师"
+}
+```
+
+```json
+{
+    "success": true,
+    "message": "用户创建成功",
+    "data": {
+        "id": 1,
+        "username": "张三",
+        "phone": "13812345678",  // 已自动解密
+        "idCard": "110101199001011234",  // 已自动解密
+        "email": "zhangsan@example.com",
+        "bankCard": "6222021234567890123",
+        "address": "北京市朝阳区建国路88号",
+        "age": 34,
+        "gender": "男",
+        "occupation": "软件工程师",
+        "enabled": true,
+        "createTime": "2024-01-01 10:00:00",
+        "updateTime": "2024-01-01 10:00:00"
+    }
+}
+```
+
+## 🔍 查看加密效果
+
+### 数据库中的存储格式
+
+在 H2 控制台中查看 users 表，可以看到加密字段存储的是加密后的密文：
+
+```sql
+SELECT phone, id_card, email FROM users WHERE username = '张三';
+```
+
+输出示例：
+```
+phone    | "AbCdEfGhIjKlMnOp:sDeFgHiJkLmNoPqRsTuVwXyZ123456789"
+id_card  | "XyZaBcDeFgHiJkLm:PqRsTuVwXyZ1234567890AbCdEfGhIj"
+email    | "MnOpQrStUvWxYzA:bCdEfGhIjKlMnOpQrStUvWxYzA123456"
+```
+
+### 应用中的显示格式
+
+通过 API 查询时，自动返回解密后的明文：
+
+```json
+{
+    "phone": "13812345678",
+    "idCard": "110101199001011234",
+    "email": "zhangsan@example.com"
+}
+```

 // 查询数据 - 自动解密敏感字段
 User result = userMapper.findById(user.getId());
 System.out.println(result.getPhone());  // 输出: 13812345678 (已自动解密)
-```
-
-### 支持的加密字段
-
-- ✅ 手机号
-- ✅ 身份证号
-- ✅ 邮箱
-- ✅ 银行卡号
-- ✅ 家庭住址
-- ✅ 其他字符串类型敏感信息
-
-## 🔧 核心原理
-
-### 1. 注解机制
-
-```java
-@Target(ElementType.FIELD)
-@Retention(RetentionPolicy.RUNTIME)
-public @interface Encrypted {
-    Algorithm algorithm() default Algorithm.AES_GCM;
-    boolean searchable() default false;
-}
-```
-
-### 2. TypeHandler 自动处理
-
-```java
-@MappedJdbcTypes(JdbcType.VARCHAR)
-@MappedTypes(String.class)
-public class EncryptTypeHandler extends BaseTypeHandler {
-
-    @Override
-    public void setNonNullParameter(PreparedStatement ps, int i, String value, JdbcType jdbcType) {
-        // 写入数据库时自动加密
-        ps.setString(i, CryptoUtil.encrypt(value));
-    }
-
-    @Override
-    public String getNullableResult(ResultSet rs, String columnName) {
-        // 从数据库读取时自动解密
-        return CryptoUtil.decrypt(rs.getString(columnName));
-    }
-}
-```
-
-### 3. 自动注册机制
-
-通过 `ObjectWrapperFactory` 自动识别标记了 `@Encrypted` 注解的字段，并注册相应的 TypeHandler。
-
-## 🔐 安全特性
-
-### 加密算法
-- **算法名称**：AES-GCM
-- **密钥长度**：256位
-- **IV长度**：12字节（随机生成）
-- **认证标签**：128位
-
-### 密钥管理
-```java
-// 默认密钥（生产环境请使用安全的密钥管理系统）
-String secretKey = "MySecretKey12345MySecretKey12345";
-
-// 支持运行时更新密钥
-CryptoUtil.updateKey(newSecretKey);
-
-// 生成随机密钥
-String randomKey = CryptoUtil.generateRandomKey();
-```
-
-## 📊 API 接口
-
-### 用户管理接口
-
-| 方法 | 路径 | 描述 |
-|------|------|------|
-| GET | `/api/users` | 获取所有用户 |
-| GET | `/api/users/{id}` | 获取用户详情 |
-| POST | `/api/users` | 创建用户 |
-| PUT | `/api/users/{id}` | 更新用户 |
-| DELETE | `/api/users/{id}` | 删除用户 |
-| GET | `/api/users/search` | 搜索用户 |
-| GET | `/api/users/stats` | 获取统计信息 |
-
-### 请求示例
-
-```json
-POST /api/users
-{
-    "username": "张三",
-    "phone": "13812345678",
-    "idCard": "110101199001011234",
-    "email": "zhangsan@example.com",
-    "bankCard": "6222021234567890123",
-    "address": "北京市朝阳区建国路88号",
-    "age": 34,
-    "gender": "男",
-    "occupation": "软件工程师"
-}
-```
-
-```json
-{
-    "success": true,
-    "message": "用户创建成功",
-    "data": {
-        "id": 1,
-        "username": "张三",
-        "phone": "13812345678",  // 已自动解密
-        "idCard": "110101199001011234",  // 已自动解密
-        "email": "zhangsan@example.com",
-        "bankCard": "6222021234567890123",
-        "address": "北京市朝阳区建国路88号",
-        "age": 34,
-        "gender": "男",
-        "occupation": "软件工程师",
-        "enabled": true,
-        "createTime": "2024-01-01 10:00:00",
-        "updateTime": "2024-01-01 10:00:00"
-    }
-}
-```
-
-## 🔍 查看加密效果
-
-### 数据库中的存储格式
-
-在 H2 控制台中查看 users 表，可以看到加密字段存储的是加密后的密文：
-
-```sql
-SELECT phone, id_card, email FROM users WHERE username = '张三';
-```
-
-输出示例：
-```
-phone    | "AbCdEfGhIjKlMnOp:sDeFgHiJkLmNoPqRsTuVwXyZ123456789"
-id_card  | "XyZaBcDeFgHiJkLm:PqRsTuVwXyZ1234567890AbCdEfGhIj"
-email    | "MnOpQrStUvWxYzA:bCdEfGhIjKlMnOpQrStUvWxYzA123456"
-```
-
-### 应用中的显示格式
-
-通过 API 查询时，自动返回解密后的明文：
-
-```json
-{
-    "phone": "13812345678",
-    "idCard": "110101199001011234",
-    "email": "zhangsan@example.com"
-}

    什么是 DFA 算法？
    
+                    
    
+                        DFA (Deterministic Finite Automaton) 是一种有限状态自动机，通过构建 Trie 树数据结构实现高效的多模式字符串匹配。
+                        时间复杂度从传统的 O(n×m) 优化到 O(n)，其中 n 是文本长度，m 是敏感词数量。

+# Spring Boot API Signature
+
+基于 Spring Boot 和 HMAC-SHA256 的 API 接口签名验证解决方案，提供安全可靠的接口验证机制。
+
+## 🚀 项目特性
+
+- **安全性高**：采用成熟的 HMAC-SHA256 算法，确保签名的不可伪造性
+- **易于集成**：基于 Spring Boot 拦截器机制，对现有代码侵入性小
+- **防重放攻击**：通过时间戳验证有效防止请求重放
+- **灵活配置**：支持多客户端、多密钥管理
+- **完整示例**：提供完整的使用示例和测试用例
+
+## 🛠️ 快速开始
+
+### 环境要求
+
+- JDK 8+
+- Maven 3.6+
+- Spring Boot 2.7.14
+
+### 1. 克隆项目
+
+```bash
+git clone 
+cd springboot-api-signature
+```
+
+### 2. 构建项目
+
+```bash
+mvn clean compile
+```
+
+### 3. 运行应用
+
+```bash
+mvn spring-boot:run
+```
+
+应用将在 `http://localhost:8080` 启动。
+
+## 📖 使用说明
+
+### 签名生成算法
+
+客户端需要按照以下规则生成签名：
+
+1. **准备参数**：将所有请求参数（不包括签名本身）收集到 Map 中
+2. **参数排序**：按参数名的字典序排序
+3. **参数拼接**：将排序后的参数用 `&` 连接：`key1=value1&key2=value2`
+4. **构建待签字符串**：`时间戳 + 参数字符串`
+5. **生成签名**：使用 HMAC-SHA256 算法和密钥对待签字符串进行加密
+6. **Base64 编码**：对加密结果进行 Base64 编码
+
+### 请求头设置
+
+客户端需要在请求头中包含以下字段：
+
+- `X-Api-Key`: API 密钥标识
+- `X-Timestamp`: 当前时间戳（秒级）
+- `X-Signature`: 生成的签名
+
+### 示例请求
+
+```java
+// 1. 准备参数
+Map params = new HashMap<>();
+params.put("userId", "12345");
+params.put("type", "profile");
+
+// 2. 生成时间戳
+String timestamp = String.valueOf(System.currentTimeMillis() / 1000);
+
+// 3. 生成签名
+String signature = SignatureUtils.generateSignature(params, timestamp, "your-secret");
+
+// 4. 设置请求头
+Headers headers = new Headers();
+headers.set("X-Api-Key", "client1");
+headers.set("X-Timestamp", timestamp);
+headers.set("X-Signature", signature);
+
+// 5. 发送请求
+// GET /api/protected/data?userId=12345&type=profile
+```
+
+## 配置参数说明
+
+| 参数 | 说明 | 默认值 |
+|-----|------|--------|
+| `api.security.enabled` | 是否启用签名验证 | `true` |
+| `api.security.time-tolerance` | 时间戳容忍度（秒） | `300` |
+| `api.security.enable-request-log` | 是否启用请求日志 | `true` |
+| `api.security.enable-response-log` | 是否启用响应日志 | `false` |
+
+## 🧪 测试
+
+### 1. 启动应用
+
+```bash
+mvn spring-boot:run
+```
+
+### 2. 运行客户端测试
+
+```java
+// 运行 ApiClient 的 main 方法
+// 或使用 curl 命令测试
+```
+
+### 3. 使用 curl 测试
+
+```bash
+# 1. 生成签名
+timestamp=$(date +%s)
+params="userId=12345&type=profile"
+signature=$(echo -n "${timestamp}${params}" | openssl dgst -sha256 -hmac "demo-secret-key-for-client1-2024" -binary | base64)
+
+# 2. 发送请求
+curl -X GET "http://localhost:8080/api/protected/data?userId=12345&type=profile" \
+  -H "X-Api-Key: client1" \
+  -H "X-Timestamp: ${timestamp}" \
+  -H "X-Signature: ${signature}"
+```

+# Spring Boot HTTPS双向认证演示项目
+
+这是一个Spring Boot HTTPS双向认证演示项目，展示了如何在Spring Boot应用中实现客户端和服务器的双向SSL认证。
+
+## 🚀 快速开始
+
+### 1. 环境准备
+
+确保你的环境中已安装：
+- JDK 17+
+- Maven 3.6+
+- OpenSSL (用于生成证书)
+
+### 2. 启动应用
+
+```bash
+# 编译项目
+mvn clean compile
+
+# 启动应用
+mvn spring-boot:run
+```
+
+应用启动后将在以下端口提供服务：
+- HTTP: http://localhost:8080 (自动重定向到HTTPS)
+- HTTPS: https://localhost:8443 (需要客户端证书)
+
+## 🧪 测试验证
+
+### 1. 公共接口测试 (无需客户端证书)
+
+```bash
+# 使用curl测试公共接口
+curl -k https://localhost:8443/api/public/info
+```
+
+### 2. 需要认证的接口测试 (需要客户端证书)
+
+```bash
+# 使用客户端证书测试安全接口
+curl -k --cert certs/client.p12:changeit \
+     https://localhost:8443/api/secure/data
+
+# 获取证书信息
+curl -k --cert certs/client.p12:changeit \
+     https://localhost:8443/api/certificate/info
+
+# 获取用户配置文件
+curl -k --cert certs/client.p12:changeit \
+     https://localhost:8443/api/user/profile
+```
+
+### 3. POST请求测试
+
+```bash
+# 提交数据 (需要客户端证书)
+curl -k --cert certs/client.p12:changeit \
+     -H "Content-Type: application/json" \
+     -d '{"message": "Hello Server", "data": [1, 2, 3]}' \
+     https://localhost:8443/api/secure/submit
+```

+# Spring Boot CLI 通用命令系统
+
+基于 Spring Boot + Spring Shell 的通用CLI系统，实现了"通用命令 + 动态分发"的设计模式，支持通过一个命令动态调用服务端的多个服务。
+
+## 快速开始
+
+### 1. 启动服务端
+
+```bash
+cd cli-server
+mvn spring-boot:run
+```
+
+服务端将在 http://localhost:8080 启动
+
+### 2. 启动客户端
+
+```bash
+cd cli-client
+mvn spring-boot:run
+```
+
+### 3. 使用CLI命令
+
+客户端启动后，进入Spring Shell交互模式，可使用以下命令：
+
+```shell
+# 查看帮助
+help-exec
+
+# 列出所有可用服务
+list-services
+
+# 用户服务示例
+exec userService --args list
+exec userService --args get 1
+exec userService --args count admin
+
+# 角色服务示例
+exec roleService --args list
+exec roleService --args users admin
+exec roleService --args check 1 admin
+
+# 系统服务示例
+exec systemService --args status
+exec systemService --args memory
+exec systemService --args time
+```

+# 概述
+
+本文介绍在 Spring Boot 3 中实现多维度网络带宽限速的完整方案。基于**令牌桶算法**手动实现核心逻辑，通过自定义 `HandlerInterceptor` 拦截请求、`HttpServletResponseWrapper` 包装响应流、`RateLimitedOutputStream` 控制输出速率，实现对文件下载、视频流等场景的精确速度控制。
+
+# 为什么需要带宽限速
+
+带宽限速与常见的 API 限流不同：限流控制的是**请求次数**（如每分钟100次），而限速控制的是**网络带宽**（如每秒200KB）。在实际应用中，带宽限速有着重要的业务价值：
+
+**场景一：文件下载服务**
+对于网盘或资源分发平台，免费用户限制在 200KB/s，VIP 用户提升到 2MB/s，既能保障基础体验，又能激励付费转化。
+
+**场景二：视频流媒体**
+不同清晰度对应不同带宽限制（480P 用 500KB/s，1080P 用 3MB/s），避免高码率视频占用过多服务器带宽。
+
+**场景三：API 接口保护**
+大数据量接口（如导出报表）如果没有带宽控制，单个请求可能占满整个出口带宽，影响其他用户访问。
+
+# 核心原理：令牌桶算法
+
+令牌桶算法是流量控制的经典方案，其思想非常直观：想象一个桶，系统以固定速率向桶中放入令牌，请求数据时必须从桶中取走对应数量的令牌。
+
+**核心参数解析：**
+
+**1. 桶容量（Capacity）**：决定能承受多大突发流量。容量为 200KB 时，即使桶已满，最多也只能连续发送 200KB 数据，之后必须等待令牌补充。
+
+**2. 填充速率（Refill Rate）**：决定长期平均传输速度。每秒补充 200KB 令牌，意味着平均速度就是 200KB/s。
+
+**3. 分块大小（Chunk Size）**：影响流量平滑度。将 8KB 数据拆分成 2KB×4 次写入，每次写入之间进行令牌检查，比一次性写入 8KB 更加平滑。
+
+**算法流程：**
+```
+发送数据前：
+1. 计算距离上次补充的时间差
+2. 根据 时间差 × 填充速率 计算新增令牌数
+3. 更新桶中令牌数（不超过容量上限）
+
+发送数据时：
+1. 检查令牌是否足够
+2. 足够：直接扣除令牌，发送数据
+3. 不足：计算 (缺少令牌数 / 填充速率) 得到等待时间，精确等待后发送
+```
+
+# 技术设计
+
+### 整体流程
+
+本方案采用拦截器模式，在请求处理的早期阶段完成限速组件的初始化，通过请求属性传递包装后的响应对象。
+
+```
+请求流程：
+┌─────────────────────────────────────────────────────────────────────┐
+│ 1. DispatcherServlet 分发请求                                       │
+└─────────────────────────────────────────────────────────────────────┘
+                              ↓
+┌─────────────────────────────────────────────────────────────────────┐
+│ 2. BandwidthLimitInterceptor.preHandle()                            │
+│    - 解析 @BandwidthLimit 注解                                      │
+│    - 从 BandwidthLimitManager 获取共享 TokenBucket                   │
+│    - 创建 BandwidthLimitResponseWrapper 并存入 request attribute    │
+└─────────────────────────────────────────────────────────────────────┘
+                              ↓
+┌─────────────────────────────────────────────────────────────────────┐
+│ 3. Controller 处理请求                                              │
+│    - 通过 BandwidthLimitHelper.getLimitedResponse() 获取包装后的响应 │
+│    - 向响应流写入数据（自动触发限速）                                │
+└─────────────────────────────────────────────────────────────────────┘
+                              ↓
+┌─────────────────────────────────────────────────────────────────────┐
+│ 4. BandwidthLimitInterceptor.afterCompletion()                      │
+│    - 清理资源，关闭流                                                │
+└─────────────────────────────────────────────────────────────────────┘
+```
+
+### 为什么选择 HandlerInterceptor
+
+在 Spring Boot 中实现请求处理，有两种常见方式：Filter 和 HandlerInterceptor。本方案选择 HandlerInterceptor 的关键原因是：**注解解析需要 HandlerMethod 对象**。
+
+Filter 在 DispatcherServlet 之前执行，此时还没有确定具体的处理方法，无法获取方法上的 `@BandwidthLimit` 注解。而 HandlerInterceptor 在处理器确定后执行，可以通过 `HandlerMethod` 精确获取方法级别和类级别的注解信息。
+
+### 核心组件职责
+
+| 组件 | 职责 |
+|------|------|
+| `@BandwidthLimit` | 声明式注解，配置限速参数 |
+| `BandwidthLimitInterceptor` | 拦截请求，解析注解，创建响应包装器 |
+| `BandwidthLimitManager` | 管理多维度限速桶（全局/API/用户/IP） |
+| `BandwidthLimitResponseWrapper` | 包装 HttpServletResponse，替换 OutputStream |
+| `RateLimitedOutputStream` | 实现限速逻辑，包装 TokenBucket |
+| `TokenBucket` | 令牌桶算法实现 |
+| `BandwidthLimitHelper` | 从请求属性中获取包装后的响应对象 |
+
+# 多维度限速实现
+
+本方案支持四种限速维度，满足不同业务场景需求：
+
+### 全局限速（GLOBAL）
+
+所有请求共享同一个限速桶，适合保护服务器整体出口带宽。例如设置 10MB/s 全局限制，即使有100个并发下载，总带宽也不会超过 10MB/s。
+
+```java
+@BandwidthLimit(value = 200, unit = BandwidthUnit.KB, type = LimitType.GLOBAL)
+@GetMapping("/download/global")
+public void downloadGlobal(HttpServletResponse response) throws IOException {
+    HttpServletResponse limitedResponse = BandwidthLimitHelper.getLimitedResponse(request, response);
+    // 写入数据...
+}
+```
+
+### API 维度限速（API）
+
+每个接口路径独立限速，不同接口的流量互不影响。`/api/file/download` 限制 500KB/s，`/api/video/stream` 限制 2MB/s，两个接口可以同时达到各自的速度上限。
+
+```java
+@BandwidthLimit(value = 500, unit = BandwidthUnit.KB, type = LimitType.API)
+@GetMapping("/download/file")
+public void downloadFile(HttpServletResponse response) throws IOException {
+    // 文件下载逻辑
+}
+
+@BandwidthLimit(value = 2048, unit = BandwidthUnit.KB, type = LimitType.API)
+@GetMapping("/stream/video")
+public void streamVideo(HttpServletResponse response) throws IOException {
+    // 视频流逻辑
+}
+```
+
+### 用户维度限速（USER）
+
+根据用户标识（如请求头 `X-User-Id`）进行限速，每个用户独立计算带宽。配合 `free` 和 `vip` 参数，可实现差异化服务：
+
+```java
+@BandwidthLimit(value = 200, unit = BandwidthUnit.KB, type = LimitType.USER,
+                free = 200, vip = 2048)
+@GetMapping("/download/user")
+public void downloadByUser(@RequestHeader("X-User-Type") String userType,
+                           HttpServletResponse response) throws IOException {
+    // 根据请求头 X-User-Type 自动应用 200KB/s 或 2MB/s 限速
+}
+```
+
+### IP 维度限速（IP）
+
+根据客户端 IP 地址限速，防止单个 IP 占用过多带宽。支持代理环境下的 IP 获取（X-Forwarded-For、X-Real-IP）。
+
+```java
+@BandwidthLimit(value = 300, unit = BandwidthUnit.KB, type = LimitType.IP)
+@GetMapping("/download/ip")
+public void downloadByIp(HttpServletResponse response) throws IOException {
+    // 每个独立 IP 限制 300KB/s
+}
+```
+
+# 关键代码实现
+
+### 1. 令牌桶核心算法
+
+TokenBucket 的核心在于精确的时间计算和令牌补充。使用 `System.nanoTime()` 获取纳秒级时间戳，确保高精度速率控制。
+
+```java
+public synchronized void acquire(long permits) {
+    // 1. 补充令牌
+    refill();
+
+    // 2. 计算等待时间
+    if (tokens >= permits) {
+        tokens -= permits;
+        return;
+    }
+
+    long deficit = permits - tokens;
+    long waitNanos = (deficit * 1_000_000_000L) / refillRate;
+
+    // 3. 精确等待
+    sleepNanos(waitNanos);
+
+    // 4. 等待后消费
+    tokens = 0;
+}
+
+private void refill() {
+    long now = System.nanoTime();
+    long elapsedNanos = now - lastRefillTime;
+    long newTokens = (elapsedNanos * refillRate) / 1_000_000_000L;
+    tokens = Math.min(capacity, tokens + newTokens);
+    lastRefillTime = now;
+}
+```
+
+### 2. 响应包装器
+
+HttpServletResponseWrapper 是 Servlet 规范提供的响应包装基类，通过覆盖 `getOutputStream()` 方法返回自定义的限速输出流。
+
+```java
+public class BandwidthLimitResponseWrapper extends HttpServletResponseWrapper {
+    private final TokenBucket sharedTokenBucket;  // 共享的令牌桶
+
+    @Override
+    public ServletOutputStream getOutputStream() throws IOException {
+        if (limitedOutputStream == null && sharedTokenBucket != null) {
+            // 使用共享 TokenBucket，确保多维度统计正确
+            limitedOutputStream = new RateLimitedOutputStream(
+                super.getOutputStream(),
+                sharedTokenBucket,
+                bandwidthBytesPerSecond
+            );
+        }
+        return limitedOutputStream;
+    }
+}
+```
+
+### 3. 拦截器获取包装响应
+
+拦截器在 `preHandle` 中创建响应包装器，存储到 request attribute，Controller 通过 `BandwidthLimitHelper` 获取。
+
+```java
+@Override
+public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) {
+    BandwidthLimit annotation = findAnnotation(handler);
+    if (annotation != null) {
+        // 从 Manager 获取共享 TokenBucket
+        TokenBucket bucket = limitManager.getBucket(type, key, capacity, rate);
+
+        // 创建包装器并存储
+        BandwidthLimitResponseWrapper wrappedResponse =
+            new BandwidthLimitResponseWrapper(response, bucket, bandwidthBytesPerSecond, chunkSize);
+        request.setAttribute("BandwidthLimitWrappedResponse", wrappedResponse);
+    }
+    return true;
+}
+```
+
+### 4. Controller 获取限速响应
+
+Controller 通过 `BandwidthLimitHelper.getLimitedResponse()` 获取包装后的响应，所有写入操作都会自动限速。
+
+```java
+@GetMapping("/download/global")
+public void downloadGlobal(HttpServletRequest request, HttpServletResponse response) throws IOException {
+    HttpServletResponse limitedResponse = BandwidthLimitHelper.getLimitedResponse(request, response);
+
+    limitedResponse.setContentType("application/octet-stream");
+    limitedResponse.setHeader("Content-Disposition", "attachment; filename=test.bin");
+
+    // 写入数据时自动限速
+    limitedResponse.getOutputStream().write(data);
+}
+```
+
+# 参数调优指南
+
+### 桶容量选择
+
+容量决定突发流量承受能力：
+
+| 容量设置 | 突发能力 | 适用场景 |
+|----------|----------|----------|
+| 速率 × 0.5 | 平滑，无突发 | 流量控制严格的场景 |
+| 速率 × 1.0 | 允许 1 秒突发 | 默认推荐值 |
+| 速率 × 2.0 | 允许 2 秒突发 | 需要良好首屏加载 |
+
+```java
+// 注解配置
+@BandwidthLimit(value = 200, unit = BandwidthUnit.KB, capacityMultiplier = 1.0)
+```
+
+### 分块大小选择
+
+分块大小影响流量平滑度，经验公式：`chunkSize = bandwidth / 50`
+
+| 带宽 | 推荐分块 | 理由 |
+|------|----------|------|
+| 200 KB/s | 1-4 KB | 小分块保证平滑 |
+| 1 MB/s | 4-8 KB | 平衡平滑与性能 |
+| 5 MB/s+ | 8-16 KB | 减少系统调用开销 |
+
+```java
+// 自动计算（推荐）
+@BandwidthLimit(value = 200, unit = BandwidthUnit.KB, chunkSize = -1)
+
+// 手动指定
+@BandwidthLimit(value = 200, unit = BandwidthUnit.KB, chunkSize = 4096)
+```
+
+# 总结
+
+本文基于令牌桶算法，通过 HandlerInterceptor + HttpServletResponseWrapper，在 Spring Boot 中实现了多维度带宽限速。支持全局/API/用户/IP 四种限速维度，提供实时统计监控，适用于API接口保护、文件下载、视频流等场景。

+# 像 ChatGPT 一样丝滑：Spring Boot 如何实现大模型流式（Streaming）响应？
+
+## 一、为什么需要流式响应？
+
+同样的 HTTP 请求，为什么像 ChatGPT 这类模型的回答能像打字机一样逐字输出，而我们平时写的接口却要等全部处理完才返回？
+
+问题的核心在于 **响应模式**：
+
+| 传统模式 | 流式模式 |
+|---------|---------|
+| 服务器处理完成 → 一次性返回 | 生成一部分 → 立即推送 |
+| 客户端等待总时长 = 服务器处理时间 | 客户端首字等待时间通常很短 |
+| 适合快速查询 | 适合耗时生成 |
+
+对于大模型这种 **生成式 AI**，一个响应可能需要几秒甚至几十秒。如果用传统模式，用户体验就是：
+
+```
+提问 → (10秒空白) → 答案全部出现
+```
+
+而流式响应的体验是：
+
+```
+提问 → 0.1秒后 → "我" → "认" → "为" → ... → 逐字呈现
+```
+
+实现这种效果有多种技术方案，本文将介绍基于 Spring Boot WebFlux + SSE 的实现方式。
+
+---
+
+## 二、核心技术选型
+
+实现流式响应主要有以下几种方案：
+
+| 方案 | 优点 | 缺点 | 适用场景 |
+|------|------|------|----------|
+| **SSE** | 单向推送、HTTP协议、实现简单 | 不支持双向通信 | 服务端主动推送 |
+| **WebSocket** | 双向通信、实时性强 | 实现复杂、需要额外协议 | 聊天、游戏 |
+| **长轮询** | 兼容性好 | 资源消耗大 | 低频数据更新 |
+
+**本文选择 SSE 方案**，原因如下：
+- Spring Boot 原生支持 `ResponseEntity>`
+- 基于标准 HTTP，无需额外协议协商
+- 代码简洁，易于理解和维护
+
+---
+
+## 三、项目依赖配置
+
+### 3.1 Maven 依赖
+
+```xml
+
+
+    4.0.0
+
+    
+        org.springframework.boot
+        spring-boot-starter-parent
+        3.2.0
+        
+    
+
+    com.example
+    springboot-chat-stream
+    1.0.0
+
+    
+        17
+    
+
+    
+        
+        
+            org.springframework.boot
+            spring-boot-starter-webflux
+        
+
+        
+        
+            org.projectlombok
+            lombok
+            true
+        
+    
+
+```
+
+### 3.2 关键依赖说明
+
+- **spring-boot-starter-webflux**：提供响应式 Web 支持，核心是 Reactor 的 `Flux` 类型
+- **Reactor**：响应式编程库，`Flux` 表示 0-N 个元素的异步序列
+
+---
+
+## 四、核心代码实现
+
+### 4.1 Controller 层：流式响应入口
+
+```java
+package com.example.chat.controller;
+
+import com.example.chat.service.StreamChatService;
+import lombok.RequiredArgsConstructor;
+import org.springframework.http.MediaType;
+import org.springframework.http.ResponseEntity;
+import org.springframework.web.bind.annotation.*;
+import reactor.core.publisher.Flux;
+
+@RestController
+@RequestMapping("/api/chat")
+@RequiredArgsConstructor
+@CrossOrigin(origins = "*") // 开发环境允许跨域
+public class StreamChatController {
+
+    private final StreamChatService chatService;
+
+    /**
+     * 流式聊天接口
+     * @param prompt 用户输入的问题
+     * @return 流式响应，text/event-stream 格式
+     */
+    @GetMapping(value = "/stream", produces = MediaType.TEXT_EVENT_STREAM_VALUE)
+    public ResponseEntity> streamChat(@RequestParam String prompt) {
+        return ResponseEntity.ok()
+                .header("Cache-Control", "no-cache")
+                .header("Connection", "keep-alive")
+                .body(chatService.streamResponse(prompt));
+    }
+}
+```
+
+**关键点解析：**
+
+1. `produces = MediaType.TEXT_EVENT_STREAM_VALUE`：声明返回 SSE 格式
+2. `Flux`：响应式流，可以发送多个数据块
+3. `Cache-Control: no-cache`：禁用缓存，确保实时推送
+
+### 4.2 Service 层：模拟大模型流式生成
+
+```java
+package com.example.chat.service;
+
+import lombok.extern.slf4j.Slf4j;
+import org.springframework.stereotype.Service;
+import reactor.core.publisher.Flux;
+
+import java.time.Duration;
+
+@Slf4j
+@Service
+public class StreamChatService {
+
+    /**
+     * 模拟大模型流式生成响应
+     * @param prompt 用户问题
+     * @return 按字符/词汇流式输出的响应
+     */
+    public Flux streamResponse(String prompt) {
+        log.info("收到用户提问: {}", prompt);
+
+        // 模拟大模型生成的回复内容
+        String response = mockLLMResponse(prompt);
+
+        // 将响应拆分为字符流，每 50ms 发送一个字符
+        return Flux.fromArray(response.split(""))

+                【Spring Boot 流式响应】
+                您的问题是：%s
+
+                这是一个模拟大模型流式输出的示例。
+                在实际应用中，你可以：
+                1. 接入 OpenAI API 使用 GPT-4
+                2. 接入阿里云通义千问 API
+                3. 接入本地部署的大模型
+
+                流式响应的核心是：
+                - 使用 Spring WebFlux 的 Flux
+                - 返回 text/event-stream 格式
+                - 前端使用 EventSource 或 fetch 接收
+
+                这样就能实现像 ChatGPT 一样的丝滑体验！
+                """.formatted(prompt);
+    }
+}
+```
+
+**核心逻辑：**
+
+1. `Flux.fromArray(response.split(""))`：将字符串拆分为字符数组转为流
+2. `.delayElements(Duration.ofMillis(50))`：每个字符延迟 50ms 发送
+3. `.doOnNext()/.doOnComplete()/.doOnError()`：生命周期钩子，用于日志记录
+
+### 4.3 接入真实大模型 API（扩展）
+
+```java
+// 接入 OpenAI Streaming API 的示例（伪代码）
+public Flux streamOpenAI(String prompt) {
+    WebClient webClient = WebClient.builder()
+            .baseUrl("https://api.openai.com/v1")
+            .defaultHeader(HttpHeaders.AUTHORIZATION, "Bearer YOUR_API_KEY")
+            .build();
+
+    return webClient.post()
+            .uri("/chat/completions")
+            .bodyValue(Map.of(
+                "model", "gpt-4",
+                "messages", List.of(Map.of("role", "user", "content", prompt)),
+                "stream", true
+            ))
+            .retrieve()
+            .bodyToFlux(String.class)
+            .map(this::extractContentFromSSE); // 解析 SSE 格式提取 content
+}
+```
+
+### 4.4 启动类
+
+```java
+package com.example.chat;
+
+import org.springframework.boot.SpringApplication;
+import org.springframework.boot.autoconfigure.SpringBootApplication;
+
+@SpringBootApplication
+public class ChatStreamApplication {
+    public static void main(String[] args) {
+        SpringApplication.run(ChatStreamApplication.class, args);
+    }
+}
+```
+
+### 4.5 配置文件
+
+```yaml
+server:
+  port: 8080
+
+spring:
+  application:
+    name: chat-stream-demo
+
+# 日志配置
+logging:
+  level:
+    com.example.chat: DEBUG
+```
+
+---
+
+## 五、前端对接示例
+
+### 5.1 使用 EventSource 接收流
+
+```html
+
+
+
+    
+    Spring Boot 流式响应示例
+    
+
+
+    
    Spring Boot 流式聊天
    
+    
+    
+    
    
+
+    
+
+
+```
+
+### 5.2 使用 Fetch API（推荐）
+
+```javascript
+async function streamChat(prompt) {
+    const response = await fetch(`/api/chat/stream?prompt=${encodeURIComponent(prompt)}`);
+    const reader = response.body.getReader();
+    const decoder = new TextDecoder();
+
+    while (true) {
+        const { done, value } = await reader.read();
+        if (done) break;
+
+        const chunk = decoder.decode(value);
+        console.log('收到数据:', chunk);
+        // 更新 UI
+    }
+}
+```
+
+---
+
+## 六、运行效果
+
+启动项目后，访问 `http://localhost:8080`（需添加静态页面支持），输入问题，你会看到：
+
+```
+【Spring Boot 流式响应】
+您的问题是：如何学习 Spring Boot？
+
+这是一个模拟大模型流式输出的示例。
+...
+```
+
+文字像打字机一样逐字出现，体验丝滑！
+
+
+---
+
+## 七、总结
+
+本文介绍了如何使用 Spring Boot WebFlux 实现 SSE 流式响应。核心是通过 `Flux` + `TEXT_EVENT_STREAM_VALUE` 将数据分块推送，配合前端 `EventSource` 实现逐字显示效果。相比传统一次性返回，流式响应能显著降低用户等待感知，特别适合大模型对话等耗时生成场景。
