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

客户端代码示例如下

package com.xwood.redis.cluster;@b@@b@import java.util.HashSet;@b@import java.util.Set;@b@@b@import redis.clients.jedis.HostAndPort;@b@import redis.clients.jedis.JedisCluster;@b@@b@public class JedisClusterTest {@b@@b@ @b@	public static void main(String[] args) {@b@		@b@		Set<HostAndPort> nodes = new HashSet<HostAndPort>();@b@		@b@		nodes.add(new HostAndPort("192.168.1.204", 7001));@b@		nodes.add(new HostAndPort("192.168.1.204", 7002));@b@		nodes.add(new HostAndPort("192.168.1.204", 7003));@b@		nodes.add(new HostAndPort("192.168.1.204", 7004));@b@		nodes.add(new HostAndPort("192.168.1.204", 7005));@b@		nodes.add(new HostAndPort("192.168.1.204", 7006));@b@		@b@		JedisCluster cluster = new JedisCluster(nodes);@b@		@b@		cluster.set("key424", "123456");@b@		@b@		String result = cluster.get("key424");@b@		@b@		System.out.println("cluster=========>"+result);@b@		cluster.close();@b@@b@	}@b@@b@}

二、解决方法

因jedis-2.7.0.jar版本改为jedis-3.0.1.jar版本解决问题，因为redis5.0版本需要客户端相应高版本驱动包
