这是服务端测试结果
看一下zk的状态，是不是已经挂了，或者状态不正常
看下这篇博客，也许你就懂了，链接：java.lang.IllegalStateException: zookeeper not connected1、登录服务器查看zookeeper状态运行是否正常
2、查看网络是否能够ping、或者是否有防火墙
3、windos系统请检查域名解析是否正确，可以考虑本地host文件加上zk域名解析
4、查看项目的zookeeper地址是否配置正确，超时时间是否合理，网络问题考虑增大超时时间。因为默认的timeout是5秒，如果5秒内连不上会报这个异常，修改dubbo.registry.timeout设置长一点即可
5、检查dubbo版本是否正确
