@RequestMapping(method = RequestMethod.POST, value = "/updateprofile1", consumes = "multipart/form-data")

        con.setFileType(FTP.BINARY_FILE_TYPE);
        con.enterLocalPassiveMode();

            con.enterLocalPassiveMode(); // important!
            con.setFileType(FTP.BINARY_FILE_TYPE);
            String fileName = currrentTime.getTimeInMillis() + "_" + file.getName()+".jpg";
            boolean result = con.storeFile(fileName, file.getInputStream());
            con.logout();
            con.disconnect();
            redirectAttributes.addFlashAttribute("message",
                    "You successfully uploaded " + file.getOriginalFilename() + "!");

    } catch (Exception e) {
