java连接redis主备集群 java连接redis集群方式

1、使用Jedis 连接集群会报 MOVED错误

package com.chen.demo; 


import redis.clients.jedis.Jedis; 


public class Demo { 

 public static void main(String[] args) { 


 String host = "192.168.199.130"; 

 Jedis jedis = new Jedis(host,7002); 

 String name =null; 

 name=jedis.get("myname1"); 

 String name2 = null ; 

 name2=jedis.get("myname2"); 

 String name3=null; 

 name3=jedis.get("myname3"); 

 System.out.println(name+" "+name2+" "+name3); 

 jedis.set("key1","value1"); 


 // System.out.println("connection:"+jedis.ping()); 

 } 

}

Exception in thread "main" redis.clients.jedis.exceptions.JedisMovedDataException: MOVED 1705 192.168.199.130:7001

2、需要使用JedisCluster连接redis集群
redis版本可能要高一点，目前使用2.8，，同时要引入commons-pool2.jar包

package com.chen.demo;

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

import redis.clients.jedis.HostAndPort;
import redis.clients.jedis.JedisCluster;


public class Demo3 {
public static void main(String[] args) {
Set<HostAndPort> jedisClusterNodes = new HashSet<HostAndPort>();
jedisClusterNodes.add(new HostAndPort("192.168.199.130", 7001));
jedisClusterNodes.add(new HostAndPort("192.168.199.130", 7002));
jedisClusterNodes.add(new HostAndPort("192.168.199.130", 7003));
JedisCluster jc = new JedisCluster(jedisClusterNodes);
System.out.println(jc.get("myname1"));
System.out.println(jc.get("myname2"));
System.out.println(jc.get("myname3"));


try {
jc.close();
} catch (IOException e) {
e.printStackTrace();
}

}
}
