将 Spring Web 应用程序部署到 JBoss 7.1.1 时,出现以下异常:

我有一个名为 IListener 的 ServletContextListener。当我尝试访问 WebApplicationContext 时,我收到了上述异常。但是,这在 TomEE 中有效。

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) {

}
  }

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

Java 版本是 1.6,Spring 版本是 3.0.6.RELEASE。

我不知道该怎么办。

通常,ContextLoaderListener从 Spring 开始是不错的选择。如果您没有任何特定要求,请使用该要求。总而言之,它应该是这样的:

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

如果你需要一个使用 Spring 上下文的监听器,你可以考虑扩展这个类。确保该contextInitialized()方法首先调用super实现(以便它可以为您初始化 Spring 上下文)。之后,它将通过(WebApplicationContext) servletContext.getAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE). 但是,您的contextDestroyed()方法应该首先执行自己的逻辑,最后调用其超级实现。

但是请注意,从“关注点分离”的角度来看,这不是一个非常干净的解决方案。

如果可能的话,我的建议是使用 Spring 过滤器、侦听器或拦截器。它们由 Spring 自动连接,您可以在其中使用 Spring 的全部功能。
