+# 保守升级指南 - POM 依赖安全升级
+
+## 📋 升级概述
+
+本次保守升级主要目标是**修复安全漏洞**，同时**保持系统稳定性**。我们采用最小化变更原则，只升级有安全风险的依赖版本。
+
+## 🎯 升级策略
+
+### ✅ **保持不变的组件**
+- **Spring Boot**: 保持 2.5.x 系列 (2.5.4 → 2.5.15)
+- **API 文档**: 继续使用 Swagger (springfox)
+- **核心业务逻辑**: 无需修改
+- **配置文件**: 基本无需修改
+
+### 🔄 **安全升级的依赖**
+- **MySQL 连接器**: `mysql-connector-java` → `mysql-connector-j 8.2.0` (修复 CVE-2023-22102)
+- **FastJSON**: `2.0.20` → `2.0.43` (修复多个安全漏洞)
+- **Hutool**: `5.8.11` → `5.8.25` (安全更新)
+- **JWT**: 升级到 `0.11.5` 并优化依赖结构
+- **BouncyCastle**: `bcprov-jdk15on` → `bcprov-jdk18on 1.77`
+- **其他组件**: 多个依赖的安全版本升级
+
+## 📊 **主要变更对比**
+
+| 组件 | 当前版本 | 升级版本 | 风险等级 | 变更原因 |
+|------|----------|----------|----------|----------|
+| Spring Boot | 2.5.4 | 2.5.15 | 🟢 低 | 安全补丁 |
+| MySQL Connector | mysql-connector-java | mysql-connector-j 8.2.0 | 🟡 中 | CVE-2023-22102 |
+| FastJSON | 2.0.20 | 2.0.43 | 🟢 低 | 安全漏洞修复 |
+| Hutool | 5.8.11 | 5.8.25 | 🟢 低 | 安全更新 |
+| JWT | 0.11.2 | 0.11.5 | 🟡 中 | 依赖结构优化 |
+| Druid | 1.2.6 | 1.2.20 | 🟢 低 | 稳定性提升 |
+
+## 🚀 **升级步骤**
+
+### 第一步: 备份当前环境
+```bash
+# 1. 备份当前 pom.xml
+cp pom.xml pom-backup-$(date +%Y%m%d).xml
+
+# 2. 提交当前代码到版本控制
+git add .
+git commit -m "备份：升级前的稳定版本"
+git tag v1.5.2-before-upgrade
+```
+
+### 第二步: 应用新的 POM 文件
+```bash
+# 1. 替换 POM 文件
+cp pom-conservative-upgrade.xml pom.xml
+
+# 2. 清理并重新构建
+mvn clean
+mvn dependency:resolve
+```
+
+### 第三步: 验证依赖
+```bash
+# 检查依赖冲突
+mvn dependency:tree
+
+# 检查安全漏洞
+mvn org.owasp:dependency-check-maven:check
+```
+
+### 第四步: 测试验证
+```bash
+# 1. 编译测试
+mvn clean compile
+
+# 2. 运行单元测试
+mvn test
+
+# 3. 启动应用测试
+mvn spring-boot:run
+```
+
+## ⚠️ **可能需要的配置调整**
+
+### 1. MySQL 连接器变更
+由于从 `mysql-connector-java` 升级到 `mysql-connector-j`，可能需要检查：
+
+```yaml
+# application.yml - 通常无需修改，但建议验证
+spring:
+  datasource:
+    driver-class-name: com.mysql.cj.jdbc.Driver  # 确认驱动类名
+```
+
+### 2. JWT 依赖结构变更
+新的 JWT 依赖结构更加模块化，如果有自定义 JWT 配置，请验证：
+
+<augment_code_snippet path="src/main/java/com/gxwebsoft/common/core/config" mode="EXCERPT">
+````java
+// 检查 JWT 相关的配置类是否需要调整
+// 通常无需修改，但建议测试 JWT 功能
+````
+</augment_code_snippet>
+

+```bash
+# 检查 MySQL 连接器版本兼容性
+mvn dependency:tree | grep mysql
+```
+
+### 问题3: JWT 功能异常
+```bash
+# 检查 JWT 相关依赖
+mvn dependency:tree | grep jjwt
+```
+

+
+## 📞 **技术支持**
+
+如果在升级过程中遇到问题，请：
+
+1. **检查日志**: 查看详细的错误信息
+2. **回滚方案**: 使用备份的 POM 文件快速回滚
+3. **逐步排查**: 可以先注释掉有问题的依赖，逐个测试
+
+## 🎉 **升级完成确认**
+
