异常原因：
zookeeper未启动。
解决方法：

再次启动tomcat，成功。

直接在window下运行dubbo的jar 包

1.首先开启

若没有错误

下载dubbo的客户端

开启命令行打包直接在地址栏中输入 cmd 回车会产生一个jar包

打包dubbo-admin

mvn clean package -Dmaven.test.skip=true

运行

4、运行dubbo-admin 直接在地址栏中输入 cmd 回车

java -jar dubbo-admin-0.0.1-SNAPSHOT.jar 运行管理控制台

正常启动

在浏览器中输入localhost :7001

用户名密码时 root
