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"
        at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
        at java.lang.Integer.parseInt(Integer.java:492)
        at java.lang.Integer.valueOf(Integer.java:582)
        at redis.clients.util.ClusterNodeInformationParser.getHostAndPortFromNodeLine(ClusterNodeInformationParser.java:40)
        at redis.clients.util.ClusterNodeInformationParser.parse(ClusterNodeInformationParser.java:14)
        at redis.clients.jedis.JedisClusterInfoCache.discoverClusterNodesAndSlots(JedisClusterInfoCache.java:40)
        at redis.clients.jedis.JedisClusterConnectionHandler.initializeSlotsCache(JedisClusterConnectionHandler.java:50)
        at redis.clients.jedis.JedisClusterConnectionHandler.<init>(JedisClusterConnectionHandler.java:31)
        at redis.clients.jedis.JedisSlotBasedConnectionHandler.<init>(JedisSlotBasedConnectionHandler.java:17)
        at redis.clients.jedis.JedisCluster.<init>(JedisCluster.java:51)
        at redis.clients.jedis.JedisCluster.<init>(JedisCluster.java:35)
        at redis.clients.jedis.JedisCluster.<init>(JedisCluster.java:26)
        at redis.clients.jedis.JedisCluster.<init>(JedisCluster.java:30)
        at com.xwood.redis.cluster.JedisClusterTest.main(JedisClusterTest.java:23)

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", 7001));
            nodes.add(new HostAndPort("192.168.1.204", 7002));
            nodes.add(new HostAndPort("192.168.1.204", 7003));
            nodes.add(new HostAndPort("192.168.1.204", 7004));
            nodes.add(new HostAndPort("192.168.1.204", 7005));
            nodes.add(new HostAndPort("192.168.1.204", 7006));
             
            JedisCluster cluster = new JedisCluster(nodes);
             
            cluster.set("key424", "123456");
             
            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
