一个项目启动不起来了，报错如题：
代码语言：javascript复制Caused by: org.I0Itec.zkclient.exception.ZkTimeoutException: Unable to connect to zookeeper server within timeout: 5000

at com.alibaba.dubbo.registry.zookeeper.ZookeeperRegistryFactory.createRegistry(ZookeeperRegistryFactory.java:37)出错原因： zookeeper 地址配置错了，用的是已废弃的一个服务器上的 zookeeper 服务。
注释掉已废弃地址，改为最新地址：
代码语言：javascript复制#dubbo.registry.address=zookeeper://116.1xx.xx.xx:2181 // 已废弃地址
dubbo.registry.address=zookeeper://xxx.x4.1xx.xx:2181?register=false
dubbo.registry.client=zkclient地址配置对了，服务就能正常启动了。
