编写接口类

  
        package cn.itcast.dubbox.service;
        
        public interface UserService {
            
            public String getName();
        
        }

编写实现类

        package cn.itcast.dubbox.service.impl;

        import com.alibaba.dubbo.config.annotation.Service;
        
        import cn.itcast.dubbox.service.UserService;
        
        //dubbo的service注解  用于向zookeeper注册服务
        
        @Service
        public class UserServiceImpl implements UserService {
        
            public String getName() {
                return "itcast";
            }
        }

编写spring配置文件

        
        
        
            //项目名，填写自己的项目名  我的项目名称叫做 dubbox-service
            
            //这里填写zk的IP以及对应的端口号
            
            //dubbox 的包扫描

   package cn.itcast.dubbox.controller;

    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    import com.alibaba.dubbo.config.annotation.Reference;
    
    import cn.itcast.dubbox.service.UserService;
    
    @RestController
    public class indexController {
        
        @Reference
        UserService userService;
        
        @RequestMapping("/getName")
        public String getName(){
            return userService.getName();
        }
    
    }

编写springmvc.xml文件

启动zk

启动service
