            for (int i = 1; i <= 10; i++) {
                list.add(get(i));
            }

            res.put("id", id);

因为使用注解来创建服务，所以就把生成者的配置文件创建UserServiceImpl类和指定接口给注释了

3、消费端

3.3、application-consumer.xml

![复制代码][copycode.gif]

3.4、ClientTest.java

![复制代码][copycode.gif]

package com.mujourney.service;
    
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.stereotype.Component;
    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    
    import com.alibaba.dubbo.config.annotation.Reference;
    
    @Component
    @RunWith(SpringJUnit4ClassRunner.class)
    @ContextConfiguration(locations={"/application-consumer.xml"})
    public class ClientTest {
        
        @Reference(interfaceName="com.mujourney.service.UserService")
        private UserService uservice;
        
        @Test
        public void pors()  {
            System.out.println(uservice.findById(1));
        }
    }

4、服务的接口端

4.1、项目结构

![917107-20170120220440593-603076788.png][]

4.2 pom.xml

![复制代码][copycode.gif]

4.3、UserService.java

![复制代码][copycode.gif]

package com.mujourney.service;
    
    import java.util.List;
    import java.util.Map;
    
    public interface UserService {
    
         public Map<String, Object> findById(int id);  
         
         public List<Map<String, Object>> queryList();  
    }

![复制代码][copycode.gif]

之所以有一个服务的接口端，因为生产者和消费者都要用到接口，把接口单独作为maven的java项目可以打jar包放到私库给生产端和消费端同时使用。
