4 Java操作redis

如果单机的情况下，使用

    Jedis jedis = new Jedis("172.16.255.231",6379);
    jedis.set("name","lijia");
    System.out.println(jedis.get("name"));

如果集群的情况下

import java.util.HashSet;
import java.util.Set;
public class RedisUtils {
public static void main(String[] args) {
    Set<HostAndPort> jedisClusterNodes = new HashSet<HostAndPort>();
    JedisCluster jc=null;
    jedisClusterNodes.add(new HostAndPort("172.16.255.231", 7001));
    jedisClusterNodes.add(new HostAndPort("172.16.255.231", 7002));
    jedisClusterNodes.add(new HostAndPort("172.16.255.231", 7003));
    jedisClusterNodes.add(new HostAndPort("172.16.255.231", 7004));
    jedisClusterNodes.add(new HostAndPort("172.16.255.231", 7005));
    jedisClusterNodes.add(new HostAndPort("172.16.255.231", 7006));
    jc=new JedisCluster(jedisClusterNodes);
    long starttime=System.currentTimeMillis();
    System.out.println(jc.get("foo")); //传入key值
}

如果都不报错说明正常，但是连接之前先检查服务器防火墙是否关闭。
