Redis单机版和集群版测试、对于java客户端的区别

 

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

2、集群版本是JedisCluster对象可以直接执行Redis的命令

 3、Redis单机版和集群版测试用例：

package com.taotao.rest.jedis;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisCluster;
import redis.clients.jedis.JedisPool;

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