- [ ] pom.xml：引入MRS定制jedis、commons-pool2、spring-boot-starter-data-redis
- [ ] pom.xml：排除Lettuce依赖、排除Tomcat容器，引入Jetty
- [ ] pom.xml：显式声明resources资源目录，避免配置文件加载失败
- [ ] application.properties：配置集群nodes、username、password、ssl参数
- [ ] 代码层：RedisTemplate泛型严格使用 <Object, Object>
- [ ] 清理冗余：删除所有Kerberos配置、keytab文件、krb5.conf文件
- [ ] 清理冗余：删除所有自定义RedisConfig配置类
- [ ] 编译验证：执行mvn clean package，无报错
- [ ] 启动测试：curl读写接口验证集群连通性
