SpringDataRedis入门

一.介绍

     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

二.入门小Demo

  1).建一个maven工程 导入依赖

    1.导入Jedis和Spring-Data-Redis依赖,及spring相关依赖    测试依赖junit

    2.配置文件

     redis-config.properties

   3.测试

    

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring/applicationContext-redis.xml")
public class RedisHashTest { //hash类型测试类
    @Autowired
    private RedisTemplate redisTemplate; //spring依赖注入

    @Test
    public void setValue(){
