项目下载地址：

https://gitee.com/empirefree/Springboot_dubbo_zk

注意点：

1. dubbo下载的类似父子项目，需要将master的pom.xml中jdk版本修改成系统jdk版本，否则会无法mvn打包，如下图

   

2. 下载的软件版本需对应，否则很容易出现各种高低版本不兼容的情况

3. 代码中@Server，@Reference需要注意到底是dubbo包的还是spring下的

启动流程：

1. 运行zk-server、zk-cli

2. java -jar dubbo-admin-0.0.1-SNAPSHOT.jar
   

   3. 访问http://localhost:7001/ ，依次启动Producer、Consumer即可

运行结果：
