commons_fileupload实现文件上传

public void doPost(HttpServletRequest request, HttpServletResponse response)
   throws ServletException, IOException {

  response.setContentType("text/html");
  PrintWriter out = response.getWriter();
  DiskFileUpload fu = new DiskFileUpload();
   fu.setSizeMax(2*1024*1024);
   fu.setSizeThreshold(4096);
   fu.setRepositoryPath("c:\\temp");
   try {
   List fileItems = fu.parseRequest(request);
   Iterator iter = fileItems.iterator();
   while (iter.hasNext()) {
      FileItem item = (FileItem) iter.next();
      //忽略其他不是文件域的所有表单信息
      if (!item.isFormField()) {
       String name = item.getName();
       name=name.substring(name.lastIndexOf("\\")+1);  
       System.out.println(name);
       File f=new File ("D:\\UploadTest\\"+name);
       item.write(f);
     }
   }
  } catch (Exception e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }

  out.close();
 }
