@SuppressWarnings("resource") 
    @RequestMapping("/editprofilehandler") 
    public ModelAndView editProfileHandlerController(@ModelAttribute("userForm") Users users , ModelMap model, HttpSession session) 
    {  
     if(session.getAttribute("session_user") != null){ 
      try 
      { 
       InputStream inputStream = null; 
       OutputStream outputStream = null; 
       MultipartFile file = users.getImage(); 
       String fileName = file.getOriginalFilename(); 
       inputStream = file.getInputStream(); 

       File newFile = new File("C:/Documents and Settings/smart/workspace/Pir/WebContent/resources/images/profile/" + fileName); 
       if(!newFile.exists()) 
       { 

       } 
       outputStream = new FileOutputStream(newFile); 
       int read = 0; 
       byte[] bytes = new byte[1024]; 

       while((read = inputStream.read(bytes)) != -1) 
        outputStream.write(bytes, 0, read); 

      } 
      catch(Exception e){} 
      List<Object[]> userDetails = this.userFunctionsService.getUserDetails(((UserLoginDetails)session.getAttribute("session_user")).getEmailID()); 
      model.addAttribute("userDetails", userDetails); 
      return new ModelAndView("editProfile", model); 
     } 
     else 
      return new ModelAndView("redirect:/"); 
    }

@Table(name = "users") 
public class Users { 
    private MultipartFile image; 

    //getters and setters 
}

MultipartFile不是JPA实体的有效类型。

例如，您可以使用以@Lob注明的字段和byte[]类型注解。

我有这个，

@RequestMapping(value = "import-data", method = RequestMethod.POST) 
public String importData(
     @PathVariable("organization") Integer organization, 
     @RequestPart("file") **MultipartFile** multipartFile, ModelMap modelMap) {  
multipartFile.getInputStream()

在我的HTML

<form method="post" action="import-data" 
       enctype="multipart/form-data"> 

<input type="file" name="file" 
          class="input-block-level btn btn-default" />

和..我保存的InputStream在dabase – jrey

我节省了其他用户的详细信息，除了文件。所以我正在使用modelAttributes。 –
