Jakarta ee 从筛选器重定向时出现问题

我在Spring3MVCWeb应用程序中遇到了一个过滤器问题。我的环境配置如下：SpringSource工具套件、JDK 7、Tomcat 7、Maven 3.0.2、Hibernate 3和MySQL 5数据库

我想要的是：

• 实现一个过滤器，以便它处理所有传入的HTTP请求（执行一些URL阻塞），然后将请求转发给Spring处理程序映射器

我得到的是：

• 当我启动服务器（Tomcat）时，一切正常，并显示主页面（index.jsp）
• 调试时，我可以看到筛选器正在按预期拦截HTTP请求并转发到链中的下一个筛选器。但是，当我尝试从主页中的链接访问URL时，该链接被映射到使用DefaultAnnotationHandlerMapping（例如用@RequestMethod（）注释）的方法，它会截取URL，但转发没有按预期工作（似乎没有被DefaultAnnotationHandlerMapping截取），并显示错误404（资源不可用）在浏览器中

为向您提供一些信息，以下是我的文件：

我错过了什么？

提前感谢！

我在你的过滤器中没有看到重定向…你能澄清一下吗？这个问题已经解决了！谢谢你的帮助！
