拉分支配项目环境，Tomcat启动报错如下:
2018-11-05 16:06:49,837 WARN [org.apache.zookeeper.ClientCnxn] - Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect

at org.apache.zookeeper.ClientCnxnSocketNIO.doTransport(ClientCnxnSocketNIO.java:361)原因:zk连接地址错误，检查发现所有provider的zk地址端口都正确，但是漏了restful项目的zk地址配置没改，改过来就好了。
