客户端报错：

org.apache.curator.CuratorConnectionLossException: KeeperErrorCode = ConnectionLoss

查看服务端zookeeper日志发现：

EndOfStreamException: Unable to read additional data from client, it probably closed the socket: address = /175.190.113.233:1688, session = 0x0
	at org.apache.zookeeper.server.NIOServerCnxn.handleFailedRead(NIOServerCnxn.java:163)

原来是因为配置的超时时间太短，Zookeeper没有读完客户端的数据就被迫断开了连接。。

在application中设置connection-timeout的值为40000，再试一下。

重新启动服务，启动成功，耶。
