1、单机版是直接从JedisPool的getresource()方法获取Jedis对象；

 <!-- jedis客户端单机版 -->
    <bean id="redisClient" class="redis.clients.jedis.JedisPool">
        <constructor-arg name="host" value="192.168.22.16"></constructor-arg>
        <constructor-arg name="port" value="6379"></constructor-arg>
        <constructor-arg name="poolConfig" ref="jedisPoolConfig"></constructor-arg>
    </bean>

2、集群版本是JedisCluster对象可以直接执行Redis的命令

<bean id="redisClient" class="redis.clients.jedis.JedisCluster">
</bean>

3、Redis单机版和集群版测试用例：

package com.taotao.rest.jedis;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import redis.clients.jedis.HostAndPort;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisCluster;
import redis.clients.jedis.JedisPool;

import java.io.IOException;
import java.util.HashSet;
