1、demo-base中pom.xml引入dubbo以及zookeeper相关

    
        
     
      com.alibaba
         
     
      dubbo
         
     
      2.8.4
         
             
                  
       
        spring
                   
       
        org.springframework
               
          
     
    
    
        
     
      org.apache.zookeeper
         
     
      zookeeper
         
     
      3.4.6
     
    
    
        
     
      com.101tec
         
     
      zkclient
         
     
      0.7
     
    

2、创建module:demo-provider

1）工程结构如下

2）pom.xml

    
        
             
      
       demo
              
      
       com.company
              
      
       1.0.0
          
         
     
      4.0.0
         
     
      demo-provider
         
     
      war
         
             
                  
       
        com.company
                   
       
        demo-service
                   
       
        1.0.0
               
              
                  
       
        com.company
                   
       
        demo-api
                   
       
        1.0.0
               
          
     
    

3）UserApiImpl.java

package com.company.provider.impl;import com.alibaba.dubbo.config.annotation.Service;import com.company.api.dto.UserDTO;import com.company.api.iapi.UserApi;import com.company.data.model.User;import com.company.service.UserService;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.BeanUtils;import org.springframework.beans.factory.annotation.Autowired;/** * Created by wsyi on 2016/11/29. */@Servicepublic class UserApiImpl implements UserApi {    private static final Logger LOGGER = LoggerFactory.getLogger(UserApiImpl.class);    @Autowired    private UserService userService;    @Override    public UserDTO qryById(Long id) {        UserDTO userDTO = new UserDTO();        User user = userService.qryUserById(id);        BeanUtils.copyProperties(user,userDTO);        return userDTO;    }}

注意：@Service为com.alibaba.dubbo.config.annotation.Service，非Spring中注解Service。

4）spring-config.xml

5）spring-provider.xml:

6）dubbo.properties

7）web.xml

    
        
             
      
       contextConfigLocation
              
      
       classpath:META-INF/spring/spring-*.xml
          
         
             
      
       org.springframework.web.context.ContextLoaderListener
          
     
    

3、demo-provider运行

1）启动zookeeper、dubbo-admin服务。

2）将demo-provider部署到tomcat上，启动服务。

3）dubbo-admin服务
