SpringDataRedis操作Redis简单案例

Jedis

　　Jedis是Redis官方推出的一款面向Java的客户端，提供了很多接口供Java语言调用。可以在Redis官网下载，当然还有一些开源爱好者提供的客户端，如Jredis、SRP等等，推荐使用Jedis。

Spring Data Redis

　　spring-data-redis是spring大家族的一部分，提供了在srping应用中通过简单的配置访问redis服务，对reids底层开发包(Jedis, JRedis, and RJC)进行了高度封装，RedisTemplate提供了redis各种操作、异常处理及序列化，支持发布订阅，并对spring 3.1 cache进行了实现。

​ spring-data-redis针对jedis提供了如下功能：

1. 连接池自动管理，提供了一个高度封装的“RedisTemplate”类

2. 针对jedis客户端中大量api进行了归类封装,将同一类型操作封装为operation接口

• ValueOperations：简单K-V操作

• SetOperations：set类型数据操作

• 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

简单案例：
