一、前言
关于redis5.0的集群模式下，通过客户端测试代码调试报"Exception in thread "main" java.lang.NumberFormatException: For input string: "7003@17003..7002@17002"等异常，详情日志如下>>
Exception in thread "main" java.lang.NumberFormatException: For input string: "7003@17003"

客户端代码示例如下:
package com.xwood.redis.cluster;
import java.util.HashSet;
import java.util.Set;
import redis.clients.jedis.HostAndPort;
import redis.clients.jedis.JedisCluster;
public class JedisClusterTest {
public static void main(String[] args) {
Set<HostAndPort> nodes = new HashSet<HostAndPort>();
nodes.add(new HostAndPort("192.168.1.204", ));
nodes.add(new HostAndPort("192.168.1.204", ));
nodes.add(new HostAndPort("192.168.1.204", ));
nodes.add(new HostAndPort("192.168.1.204", ));
nodes.add(new HostAndPort("192.168.1.204", ));
nodes.add(new HostAndPort("192.168.1.204", ));
JedisCluster cluster = new JedisCluster(nodes);
cluster.set("key424", "");
String result = cluster.get("key424");
System.out.println("cluster=========>"+result);
cluster.close();
}
}
二、解决方法
因jedis-2.7.0.jar版本问题，改为jedis-3.0.1.jar版本就能解决问题，因为redis5.0版本需要客户端相应高版本驱动包
