dubbo2.7.7啓動Caused by: java.lang.IllegalStateException: zookeeper not connected

啓動dubbo可能出現如下錯誤：

Caused by: java.lang.IllegalStateException: zookeeper not connected
	at org.apache.dubbo.remoting.zookeeper.curator.CuratorZookeeperClient.<init>(CuratorZookeeperClient.java:80) ~[dubbo-2.7.7.jar:2.7.7]
	... 31 more

首先確定下zookeeper服務是否正常，如果zk正常，那基本就是連接zk出現異常，進入錯誤類斷點調試下，如果連接超時可以將timeout屬性設置大一些，默認5*1000。

屬性設置：

dubbo:
  application:
    name: privider
  registry:
    address: zookeeper://127.0.0.1:2181
    timeout: 10000
