dubbo入门

新建一个空项目，再建2个module:provider,consumer

用到以下依赖及插件，pom文件如下：

          8082
          /
        
      
    

在provider中提供服务，接口及实现类，目录结构如下所示：

applicationContext-service.xml如下所示：

web.xml配置监听器，加载spring容器

  Archetype Created Web Application
  
    contextConfigLocation
    classpath:applicationContext-service.xml
  
  
    org.springframework.web.context.ContextLoaderListener
  

 

consumer中的controller及文件结构如下所示

 web.xml:

  
  Archetype Created Web Application
  
    consumer
    org.springframework.web.servlet.DispatcherServlet
    
    
      contextConfigLocation
      classpath:applicationContext-web.xml
    
    1
  
  
    consumer
    
    /
  

applicationContext-web.xml 

 注意一下：context:component-scan的设置，否则会出现 错误，，，
