Spring MVC Hibernate file upload error

Question

I am trying to write a program where user uploads file to the server. Here is the code.

Controller.java

@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:/");
    }

Users.java

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

    //getters and setters
}

Error:

How to solve this error?

Answer 1

MultipartFile is not a valid type for a JPA entity.

You can use a field annotated with @Lob and a type byte[] for example.

Answer 2

I have this,

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

In my html

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

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