java - Stripes 异常处理程序错误

Question

我在“/”中有一个index.jsp文件，内容如下:

<%@include file="/WEB-INF/jsp/common/taglibs.jsp" %>

    <c:choose>
        <c:when test='<%=session.getAttribute("consumer") != null%>'>
            <jsp:forward page="/Ledger.action"/>
        </c:when>
        <c:otherwise>
            <jsp:forward page="/Login.action"/>             
        </c:otherwise>
    </c:choose>

在我的 web.xml 文件中，我放置了如下条目:

  <error-page>
    <error-code>404</error-code>
    <location>/index.jsp</location>
  </error-page>

我编写了一个自定义异常处理程序，如下所示:

public class MyExceptionHandler extends DefaultExceptionHandler {
    public Resolution catchActionBeanNotFound(
                ActionBeanNotFoundException exc,
                HttpServletRequest request,
                HttpServletResponse response
            ) {
        return new ErrorResolution(HttpServletResponse.SC_NOT_FOUND);
    }
}

当用户未登录时，意味着'session.getAttribute("consumer") == null'如果我们使用无效的url，它将被重定向到'登录.action' 页面，但登录后，在使用无效网址时，我从 tomcat 收到 HTTP Status 404 错误，而不是重定向到“Ledger.action” '

在 eclipse 控制台中，我收到如下错误:

SEVERE: Exception Processing ErrorPage[errorCode=404, location=/index.jsp] org.apache.jasper.JasperException: A request made it through to some part of Stripes without being wrapped in a StripesRequestWrapper. The StripesFilter is responsible for wrapping the request, so it is likely that either the StripesFilter is not deployed, or that its mappings do not include the DispatcherServlet and *.jsp. Stripes does not require that the Stripes wrapper is the only request wrapper, or the outermost; only that it is present.

以下是我的 web.xml 文件:

Answer 1

我必须在 web.xml 的过滤器映射部分添加以下内容:

<dispatcher>ERROR</dispatcher>

然后整个条目将如下所示:

  <filter-mapping>
    <filter-name>StripesFilter</filter-name>
    <servlet-name>DispatcherServlet</servlet-name>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>ERROR</dispatcher>
  </filter-mapping>
