    nested exception is java.lang.IllegalArgumentException: argument type mismatch
java.lang.IllegalArgumentException: argument type mismatch

コントローラークラスは

 @RequestMapping(value = "/Upload.html", method = RequestMethod.POST)
protected ModelAndView onSubmit(HttpServletRequest request,
        HttpServletResponse response, Object command, BindException errors,HttpSession session)  {
    System.out.println("inside submit method");
    try{
    UploadItem item=(UploadItem)command;
    MultipartFile file = item.getFile();
    InputStream inputStream = null;
    OutputStream outputStream = null;
    if (file.getSize() > 0) {
        inputStream = file.getInputStream();
        outputStream = new FileOutputStream("D:/UploadedFiles/Images/"
                + file.getOriginalFilename());
        System.out.println(file.getOriginalFilename());
        int readBytes = 0;
        byte[] buffer = new byte[8192];
        while ((readBytes = inputStream.read(buffer, 0, 8192)) != -1) {

そして私のhtmlページは

<input type="text" id="box"/> 
<input type="file" id="UploadFile" name="UploadFile"  onchange="CopyMe(this,'box');" accept="image/*" size="40" style="width: 91px;" multiple />
<br><br>  
<input type="submit" value="Upload" /><br><br>
</div>
</form>
