Struts2排除模式不起作用

我正在使用基于GAE的应用程序的struts2。 我有一个servlet来上传这样的文件 –

@Override protected void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException { try{ ServletFileUpload upload = new ServletFileUpload(); FileItemIterator it = upload.getItemIterator(req); while (it.hasNext()){ FileItemStream item = it.next(); if(item.isFormField()){ System.out.println(item.getFieldName()); }else { System.out.println(item.getFieldName()+" : "+item.getName()); } } }catch (Exception e){ } } 

在我的struts.xml中，我添加了exclude pattern，如下所示

这是我的web.xml的片段

  struts2 org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter  actionPackages com.tutorial.action    struts2 /* REQUEST FORWARD   sitemesh com.opensymphony.sitemesh.webapp.SiteMeshFilter   sitemesh /* REQUEST FORWARD INCLUDE   ImageUpload com.tutorial.servlet.ImageUploadServlet   ImageUpload /upload/file  

当我尝试上传文件时它仍然是struts而不是我的servlet。 我该如何解决这个问题？ 我想通过servlet上传文件。

这是错误的堆栈跟踪 –

Answer 1

使用这样的正则表达式样式：

Answer 2

将web.xml中的/*更改为struts2filter到您使用的特定扩展名，即*.html

Answer 3

如果您真的想要使用自定义servlet，那么struts.action.excludePattern另一种方法是定义重定向到servlet的操作。

  /upload_servlet
