java - JSF2.x : page in sub folder not accessible

Question

这是JSF2.1，JBoss 6 EAP7.1服务器项目

我想设置以下内容:

1. 用户在浏览器中输入此 URL:http://domain.com/webApp/pathA
2. 服务器检测到请求并注意到/pathA 位
3. JSF 将浏览器重定向到域名.com/webApp/pathB/b.xhtml

过滤器类运行正确，由/pathA触发并运行response.sendRedirect(contextPath + "/pathB/b.xhtml");

但是浏览器遇到错误:

[地址栏]domain.com/webApp/pathB/b.xhtml

发生错误:

/b.xhtml 在ExternalContext 中未作为资源找到

com.sun.faces.context.FacesFileNotFoundException:在ExternalContext中未找到/b.xhtml作为资源 在 com.sun.faces.facelets.impl.DefaultFaceletFactory.resolveURL(DefaultFaceletFactory.java:232) 在 com.sun.faces.facelets.impl.DefaultFaceletFactory.resolveURL(DefaultFaceletFactory.java:273) 在 com.sun.faces.facelets.impl.DefaultFaceletFactory.getMetadataFacelet(DefaultFaceletFactory.java:20

如果我直接在浏览器中输入domain.com/webApp/pathB/b.xhtml，我会收到相同的错误消息

我猜问题出在 web.xml 中，但我不明白为什么......你能帮我吗？

FormFilter.java

package com.kit.filter;

public class FormFilter implements Filter{

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {

        HttpServletRequest req = (HttpServletRequest) request;
        //HttpSession session = req.getSession();

        System.out.println("---------------------------------------------");
        System.out.println("req.getRequestURI()=" + req.getRequestURI());
        System.out.println("req.getContextPath()=" + req.getContextPath());
        System.out.println("req.getRequestURL()=" + req.getRequestURL());
        System.out.println("---------------------------------------------");

        if (req.getRequestURI().contains("pathA"))
        {
            //HttpServletResponse res = (HttpServletResponse) response;
            //res.sendRedirect("pathA/helloWorldA.xhtml");

            String contextPath = ((HttpServletRequest)request).getContextPath();

            System.out.println("~~~~~~~~~~~~~~ redirect to: " + contextPath + "/pathB/b.xhtml" );

            ((HttpServletResponse)response).sendRedirect(contextPath + "/pathB/b.xhtml");

        }
        else
        {
            chain.doFilter(request, response);
        }


    }

    public void init(FilterConfig filterConfig) throws ServletException {

    }

    public void destroy() {
    }


}

a.xhtml(b.xhtml 是与 a.xhtml 类似的虚拟页面)

<h:head>
    <title>Secured welcome page</title>
</h:head>
<h:body>
    <h:form>
        <h3>Welcome AAAA</h3>
        <br/>
        <h:outputText value="This is an info page. Everyone has access to it!"/>
        <br/>

    </h:form>
</h:body>
</html>

Answer 1

/pathB/* 行导致了问题，删除该行后，过滤器的重定向工作正常

<servlet-mapping>
 <servlet-name>Faces Servlet</servlet-name>
  <url-pattern>*.xhtml</url-pattern>
 </servlet-mapping>
