        public class UploadController {

            @Resource
            public UserClientService userService;

            @RequestMapping(value = "upload", method = RequestMethod.POST)
            public @ResponseBody
            String upload(HttpServletRequest request,
                          HttpServletResponse response, ModelMap model,HttpSession session) throws IOException {
                MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
                MultipartFile mFile = multipartRequest.getFile("file");
                String path = request.getSession().getServletContext().getRealPath("/resources/upload");
                String filename = mFile.getOriginalFilename();
                InputStream inputStream = mFile.getInputStream();
                byte[] b = new byte[1048576];
                int length = inputStream.read(b);
                Date date = new Date();
                SimpleDateFormat F = new SimpleDateFormat("yyyyMMddHHmmss");
                String prefix=filename.substring(filename.lastIndexOf("."));
                filename = "123" + F.format(date) + prefix;
                String url =path +"/"+ filename;
                System.out.println(url);
                FileOutputStream outputStream = new FileOutputStream(url);
                outputStream.write(b, 0, length);
                inputStream.close();
                outputStream.close();
                return "success";
