Question

我正在尝试使用web.xml中定义的过滤器捕获404错误我定义了我的过滤器

public class StatusValidationFilter implements Filter
{

    public void destroy() {
        // TODO Auto-generated method stub

    }

    public void doFilter(ServletRequest servletrequest, ServletResponse servletresponse,
            FilterChain filterchain) throws IOException, ServletException 
    {
        HttpServletResponse response = (HttpServletResponse)servletresponse;


        if (!(response instanceof StatusExposingServletResponse)) 
        {
            response = new StatusExposingServletResponse(response);
        }

        filterchain.doFilter(servletrequest, response); 

    }

    public void init(FilterConfig arg0) throws ServletException {
        // TODO Auto-generated method stub

    }

}

我像这样定义了我的包装器：

public class StatusExposingServletResponse extends HttpServletResponseWrapper 
{

    public StatusExposingServletResponse(HttpServletResponse response) {
        super(response);
    }


    public void sendError(int sc) throws IOException {

        if(sc == HttpServletResponse.SC_NOT_FOUND)
        {
            throw new RuntimeException();
        }
        super.sendError(sc);
    }

    public void sendRedirect(String location) throws IOException {
        super.sendRedirect(location);
    }


}

好的，然后在web.xml中定义了过滤器和映射，如下所示：

<filter>
      <filter-name>StatusValidationFilter</filter-name>
      <filter-class>com.test.StatusValidationFilter</filter-class>

</filter>

<filter-mapping>
        <filter-name>StatusValidationFilter</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
        <dispatcher>ERROR</dispatcher>
</filter-mapping>

但是没有捕获404错误，只是在url映射到ActionServlet映射的url时调用过滤器，这意味着，完成.do 我尝试更改WAS com.ibm.ws.webcontainer.invokeFiltersCompatibility = true中的属性，但仍然无法正常工作，我对其如何修复没有任何其他想法，任何帮助都会受到赞赏。

您需要设置

com.ibm.ws.webcontainer.invokefilterscompatibility=true

服务器中的

- ＆gt;服务器 - ＆gt; Web容器设置 - ＆gt; Web容器 - ＆gt;自定义属性。
