概述
spring中的框架,用来操作redis,封装了(Jedis,Jredis,RJC);t提供了各种操作;异常处理及序列化,支持发布订阅,并对spring3.1 cache进行了实现;
功能:
- 连接池自动管理,提供了一个高度封装的"RedisTemplate"类
- 针对jedis客户断种大量api进行了归类封装,将同易类型操作封装为operation接口
- ValueOperations: 简单K-V操作
- setOperations: set 类型数据操纵
- ZsetOperations: zset类型数据操作
- HashOperations: 针对map类型的数据操作
- ListOperations: 针对list类型的数据操作
