Question

如何将网址localhost/testproject/testfolder/all/profile.xhtml映射到localhost/testproject/profile.xhtml？我不想显示后面的文件夹的整个结构。我用URL-Pattern但它不起作用。任何人都可以给我一个提示，这在JSF 2.2中是如何工作的？

您可以使用过滤器（URL重写）为您执行此操作。

网上有很多网址重写库，或者您实现了自己的过滤器

有点像

public void doFilter(final ServletRequest request, final ServletResponse response, final FilterChain filerChain) throws IOException, ServletException { 
        HttpServletRequest httrequest = (HttpServletRequest) request;
        String url = httrequest.getRequestURI().trim();
        HttpSession session = httrequest.getSession(true);
        //be aware of infinite loops. in case your url is only profile.xhtml and the redirect contains this file too, so i added the pattern faces before it
        if (url.contains("faces/profile.xhtml")) { // this what pub User see in the url
            StringBuilder forward = new StringBuilder();                       
            forward.append("/testfolder/all/profile.xhtml?");
            forward.append(httrequest.getQueryString());
            request.getRequestDispatcher(forward.toString()).forward(request, response);


        }

                if(!response.isCommitted()){
            try{
                filerChain.doFilter(request, response);
            }catch(Exception ex){
                ...
            }
        }

你需要重写URL，我使用prettyfaces作为我的URL重写库。您甚至可以拥有友好的网址

prettyfaces

您只需将其添加到pom.xml

即可

<!-- for JSF 2.x -->
<dependency>
  <groupId>org.ocpsoft.rewrite</groupId>
  <artifactId>rewrite-servlet</artifactId>
  <version>2.0.8.Final</version>
</dependency>
<dependency>
  <groupId>org.ocpsoft.rewrite</groupId>
  <artifactId>rewrite-config-prettyfaces</artifactId>
  <version>2.0.8.Final</version>
</dependency>

然后在pretty-config.xml文件夹

中创建/WEB-INF/

在您的情况下，这是pretty-config.xml

的示例文件

<pretty-config xmlns="http://ocpsoft.org/schema/rewrite-config-prettyfaces" 
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
   xsi:schemaLocation="http://ocpsoft.org/schema/rewrite-config-prettyfaces
                  http://ocpsoft.org/xml/ns/prettyfaces/rewrite-config-prettyfaces.xsd">

   <url-mapping id="profile">
       <pattern value="/profile" />
       <view-id value="/testfolder/all/profile.xhtml" />
   </url-mapping>

</pretty-config>

JSF Map显示从localhost / testproject / testfolder / all / profile.xhtml到localhost / testproject / profile.xhtml的URL
