记zookeeper与项目配置问题

项目配置设置的zookeeper的ip路径，一定要与已启动的zookeeper服务器地址对应上，不然会一直刷新报如下错误：

WARN ClientCnxn:1162 - Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect
java.net.ConnectException: Connection timed out: no further information
at sun.nio.ch.SocketChannelImpl.checkConnect(Native Method)

21:31:57,285 DEBUG ClientCnxnSocketNIO:203 - Ignoring exception during shutdown input

如果ip路径确实一一对应，就需要去查找zookeeper服务器是否真的已启动。
