Spring文件上载和持久化对象

我有一个表单，它有两个提交按钮。保存按钮将对象保存到数据库，同时将上载文件保存到本地目录。而“发送”按钮将自动向收件人发送电子邮件

到目前为止我所拥有的

    @RequestMapping(value = "/staff/setter/addPage", method = RequestMethod.POST)
public String processModule(@RequestParam("name") String name,
        @RequestParam("file") MultipartFile file, @ModelAttribute("module") 

      Module module, Staff staff, HttpServletRequest request, BindException errors,
      HttpSession session) {    

           if( request.getParameter("save") != null )
              {
     if(module != null){

         try {

             MultipartFile filea = module.getFileData();

             InputStream inputStream = null;
             OutputStream outputStream = null;
             if (filea.getSize() > 0) {
             inputStream = filea.getInputStream();
             outputStream = new FileOutputStream("C:\\Test\\"
             + filea.getOriginalFilename());
             System.out.println("==========Uploaded File 

                   Name=========");
             System.out.println(filea.getOriginalFilename());


                    System.out.println("====================================");
             int readBytes = 0;
             byte[] buffer = new byte[8192];
             while ((readBytes = inputStream.read(buffer, 0, 8192)) != 

              -1) {
             outputStream.write(buffer, 0, readBytes);
             }
             outputStream.close();
             inputStream.close();
             session.setAttribute("success", "File Uploaded 

           Successfully");
             session.setAttribute("uploadFile", "C:\\Test\\"
             + filea.getOriginalFilename());
             }
             } catch (Exception e) {
             e.printStackTrace();
             }


 //Save specific processing
     moduleService.save(module);
     }
     return "redirect:/staff/setter/addPage";   
 }

 else if( request.getParameter("send") != null )
 {
  //Send specific processing.
     SimpleMailMessage msg = new SimpleMailMessage(this.templateMessage);
     //msg.setTo(module.getCustomer().getEmailAddress());
     msg.setTo(module.getChecker().getEmail());
     //msg.setTo(staff.getChecker().getEmail());

     msg.setText(
         "Dear " + module.getChecker().getName()
         //"Dear " + staff.getChecker().getEmail()
             //+ module.getCustomer().getLastName()
             + "a coursework has been submitted for checking"
             + module.getModuleCode()
             +module.getModuleName());
     try{
         this.mailSender.send(msg);
     }
     catch(MailException ex) {
         // simply log it and go on...
         System.err.println(ex.getMessage());   

 }

 }
return "/staff/setter/view_submission";
}

到目前为止，错误是

      HTTP Status 400 - The request sent by the client was syntactically incorrect.

我将感谢任何帮助

如果您希望避免处理多部分表单的麻烦，并可能为用户提供更好的体验。例如，您的表单数据有错误，用户需要重新提交您的文件上载将丢失的表单

我使用fineuploader构建一个uploadedfilequeue作为隐藏输入，而上传本身就是独立的请求

此处解释：

您的请求看起来像什么？您是指jsp页面吗？我将添加它。我添加了jsp页面。
