jedis是redis的java客户端，spring将redis连接池作为一个bean配置。
redis连接池分为两种，一种是“redis.clients.jedis.shardedjedispool”，这是基于hash算法的一种分布式集群redis客户端连接池。
另一种是“redis.clients.jedis.jedispool”，这是单机环境适用的redis连接池。

shardedjedispool是redis集群客户端的对象池，可以通过他来操作shardedjedis，下面是shardedjedispool的xml配置，spring-jedis.xml：

二者操作代码类似，都是先注入连接池，然后通过连接池获得jedis实例，通过实例对象操作redis。
