Spring 3 MVC調度程序xml和applicationContext xml

Question

我正在首次創建Spring MVC應用程序。

看來，當我啓動服務器時，即使在運行任何mvc控制器之前，applicationContext.xml也會首次加載;這就是我要的。

但是，一旦我運行一個加載了上下文的控制器：在dispatcher.xml中進行組件掃描.... IT SEEMS再次加載applicationContext.xml ... 這是怎麼回事？禁用這個？我只想讓我的applicationContext.xml運行一次。

緊接着我運行一個控制器，我看到下面的日誌...

ClassPathXmlA I org.springframework.context.support.AbstractApplicationContext prepareRefresh Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@65cb65cb: startup date [Tue Feb 15 16:29:21 EST 2011]; root of context hierarchy 
XmlBeanDefini I org.springframework.beans.factory.xml.XmlBeanDefinitionReader loadBeanDefinitions Loading XML bean definitions from class path resource [WEB-INF/applicationContext.xml] 

我想這也是導致要創建我的兩倍JMS使用DefaultMessageListenerContainer ...

感謝

xxxdispatcher-servlet.xml

applicationContext.xml

的web.xml

<servlet> 
    <servlet-name>xxxdispatcher</servlet-name> 
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> 
    <load-on-startup>1</load-on-startup>

    <servlet-name>xxxdispatcher</servlet-name> 
    <url-pattern>/*</url-pattern>

<listener> 
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
</listener> 

<listener> 
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> 
</listener> 
<context-param> 
    <param-name>log4jConfigLocation</param-name> 
    <param-value>/WEB-INF/log4j.properties</param-value> 
</context-param> 

控制器

@Controller 
    public class XXXController { 

     @Autowired 
     private IXXXService xxxService; 

     @RequestMapping("/xxx") 
     public String xxxHandler() throws Exception { 

      return "xxxView"; 
     }

請從你的web.xml文件中刪除的ContextLoaderListener我beleive這就是爲什麼兩次創建您的上下文的原因。
