<h3 dir="auto">Environment</h3>
<ul dir="auto">
<li>Dubbo version: 2.7.5-SNAPSHOT</li>
<li>Operating System version: windows10</li>
<li>Java version: 1.8</li>
<li>zookeeper version: 3.4.12</li>
</ul>
<h3 dir="auto">Steps to reproduce this issue</h3>
<p dir="auto">1.最近学习dubbo， 自己在用vm搭建了zookeeper 集群，系统是centos7。<br>
2. 自己的系统是win10，在idea中下载了官网的dubbo-demo，运行其中的/dubbo-demo/dubbo-demo-xml/dubbo-demo-xml-provider时，抛出异常：Exception in thread "main" java.lang.IllegalStateException: zookeeper not connected<br>
3. 只修改/dubbo-demo/dubbo-demo-xml/dubbo-demo-xml-provider/src/main/resources/spring/dubbo-provider.xml的&lt;dubbo:registry timeout="100000" address="zookeeper://192.168.71.101:2181?backup=192.168.71.102:2181,192.168.71.103:2181,192.168.71.104:2181"/&gt;<br>
地址为运行在vmare的zookeeper集群地址，联网方式是NAT</p>
<p dir="auto">Pls. provide [GitHub address] to reproduce this issue.</p>
