部署春季万维网应用程序到JBoss的WebApplicationContext例外

Question

在部署的Spring Web应用程序到JBoss 7.1.1，给出了以下异常：

12:26:58,053 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/i]] (MSC service thread 1-3) Exception sending context initialized event to listener instance of class com.listener.IListener: java.lang.IllegalStateException: No WebApplicationContext found: no ContextLoaderListener registered?

我有一个名为IListener的ServletContextListener。当我尝试访问WebApplicationContext时，我收到上述异常。但是，这在TomEE中起作用。

下面是代码：

public class IListener implements ServletContextListener { 

public IListener() { 

} 

public void contextInitialized(ServletContextEvent event) { 
    ServletContext context = event.getServletContext(); 
    WebApplicationContext webApplicationContext = WebApplicationContextUtils.getRequiredWebApplicationContext(context); 
    } 

public void contextDestroyed(ServletContextEvent event) { 

} 
    } 

的web.xml

 <display-name>JEE WebApp</display-name>

    <listener> 
     <!-- Loads your Configuration Files-->

    </listener>

    </servlet-mapping> 

    <welcome-file-list> 
     <welcome-file>index.jsp</welcome-file> 
    </welcome-file-list>  

Java版本是1.6和Spring版本3.0.6.RELEASE。

我不知道该怎么做。

Answer 1

通常，来自Spring的ContextLoaderListener是很好去。如果您没有任何特定要求，请使用该要求。所有功能于一切，这应该是这样的：

<listener> 
    <!-- Loads your Configuration Files--> 
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 
</listener> 

如果你需要有一个使用Spring上下文监听器，你可以考虑扩大这一类。确保contextInitialized()方法首先调用super实现（以便它可以为你初始化Spring上下文）。之后，它将通过(WebApplicationContext) servletContext.getAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE)提供。但是，您的contextDestroyed()方法应首先执行自己的逻辑并最终调用其超级实现。

但是请注意，从"seperation of concerns"的角度来看，这不是一个非常干净的解决方案。

我的建议是，如果可能的话，使用Spring过滤器，听众或Interceptors。它们由Spring自动自动装配，你可以在它们内部使用完整的Spring电源。
