- [ ] pom.xml：引入MRS定制jedis、commons-pool2、spring-boot-starter-data-redis
- [ ] pom.xml：排除Lettuce依賴、排除Tomcat容器，引入Jetty
- [ ] pom.xml：顯式聲明resources資源目錄，避免配置文件加載失敗
- [ ] application.properties：配置集群nodes、username、password、ssl參數(shù)
- [ ] 代碼層：RedisTemplate泛型嚴格使用 <Object, Object>
- [ ] 清理冗余：刪除所有Kerberos配置、keytab文件、krb5.conf文件
- [ ] 清理冗余：刪除所有自定義RedisConfig配置類
- [ ] 編譯驗證：執(zhí)行mvn clean package，無報錯
- [ ] 啟動測試：curl讀寫接口驗證集群連通性
