此项目 在myeclipse2014版本上正常启动。现在由于要上新项目，最低需要JDK1.8，所以升级到Myeclipse2017版本。JDK也重新安装了jdk1.8.0_162（64位）SVN检出项目，添加到 tomcat8.0 选择Exploed,启动。报错信息如下：
【报错信息中的ZookKeeper连接地址是被隐藏的】

问题解决：从这句话 INFO - Opening socket connection to server 22.33.444.00/22.33.444.00:8080. Will not attempt to authenticate using SASL (unknown error) 可以看出来，是连接的地址出错。如果是本地的Zookeeper,地址是127.0.0.1，如果不是本地的，确认远程连接地址正确，并且Zookeeper已启动。在 配置文件spring-dubbo-consumer.xml中修改。
