struts2上傳！！！

struts2的上傳，已經將request重新封裝！

 

 MultiPartRequestWrapper request = (MultiPartRequestWrapper) ServletActionContext.getRequest();
  HttpServletResponse response = ServletActionContext.getResponse();
  response.setContentType("text/html");
  response.setCharacterEncoding("utf-8");
  PrintWriter out = response.getWriter();
  File[] files =request.getFiles("image");
  String[] str = request.getFileNames("image");

 ----------------------------------------------------------------------------可以忽略以下獲得上傳檔案的步驟

 DiskFileItemFactory factory = new DiskFileItemFactory();
  ServletFileUpload upload = new ServletFileUpload(factory);
  upload.setSizeMax(1000000000);
  List fileItems = upload.parseRequest(request);
  Iterator it = fileItems.iterator();
  String name = null;
  String teee = request.getParameter("name");
  response.setCharacterEncoding("gbk");
  PrintWriter out = response.getWriter();
  while(it.hasNext()){
   FileItem item = (FileItem) it.next();
   if(item.isFormField()){
    if(item.getFieldName().equals("name")){
     name  = item.getString("gbk");
    }
   }else{
    String Path = request.getSession().getServletContext().getRealPath("/");
    String fileName = item.getName();
    String saveName =fileName.substring(fileName.lastIndexOf("/")+1);
    String savePath = Path+File.separator+saveName;
    if(item.getFieldName().equals("file")){
     File file = new File(savePath);
     file.createNewFile();
     item.write(file);
     file = null;
    }
   }
  }
