Question

我使用Java Servlets，JSP和Filters来返回网页，并在输入以下网址时不断收到404错误：

www.mysite.com/download/
www.mysite.com/store /

将传入的请求记录到过滤器时，我从未使用以下代码看到这些请求中的任何一个：

HttpServletRequest req = (HttpServletRequest) request;
System.out.println(req.getRequestURI());

但是，我看到所有其他传入请求。我错过了什么？

    <error-page>
        <exception-type>404</exception-type>
        <location>/XXXControllerServlet/*</location>
    </error-page>

获取404当页面存在时
