1.下载相关jar包，并引入工程：
jedis-2.4.2.jar
commons-pool2-2.0.jar
2.将以下XML配置引入spring
<bean id="shardedJedisPool" class="redis.clients.jedis.ShardedJedisPool">
<constructor-arg index="0" ref="jedisPoolConfig"/>
<constructor-arg index="1">
<list>
<bean name="slaver" class="redis.clients.jedis.JedisShardInfo">

<constructor-arg index="1" value="${redis.slaver.port}" type="int"/>
</bean>
<bean name="master" class="redis.clients.jedis.JedisShardInfo">
<constructor-arg index="0" value="${redis.master.host}"/>

3.将shardedJedisPool注入相关的类中即可使用
