###### 1. 模块划分设计 ######

  <tr>

###### 2. 创建父工程 ######

###### 3. 创建公共接口 ######

package com.cloud.alibaba.dubbo.service;
    
    public interface DubboService { 
    
        String hello(String name);
    }

###### 4. 服务端 ######

package com.cloud.alibaba.dubbo.service.impl;
    
    import com.cloud.alibaba.dubbo.service.DubboService;
    
    /**
     * dubbo 服务端
     */
    @org.apache.dubbo.config.annotation.DubboService
    public class DubboServiceImpl implements DubboService { 
    
        @Override
        public String hello(String name) { 
            return "hello " + name;
        }
    }

    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
    
    @SpringBootApplication
    @EnableDiscoveryClient
    public class ProviderApplication { 
    
        public static void main(String[] args) { 
            SpringApplication.run(ProviderApplication.class);
        }
    }
