How to not get an error when editing data if I will not upload any image in the user

So while I'm updating the data for the user, I ran into an error that even If i already have an image uploaded for the user in my DB, it wants to upload an image again. Can anyone tell me how to save user without uploading image but the uploaded image remains in my DB?

The error is java.IOException: Could not save image file:

caused by: java.nio.file.DirectoryNotEmptyException: profile-image/4

Here's my controller

@PostMapping("/profile/save")
public String saveProfile(Profile profile, Model model, @RequestParam("image") MultipartFile multipartFile,@RequestParam(value="userId", required=false) Long userId) throws IOException {
profile.setUser(userRepo.findById(userId).get());
String fileName = StringUtils.cleanPath(multipartFile.getOriginalFilename()) ;
String uploadDir - "profile-image/"+ profile.getId();
FileUploadUtil.saveFile(uploadDir, fileName, multipartFile);
profile.setProfileImg(fileName);
profileService.saveProfile(profile);
return "redirect:/user/profile";

There is an error in your FileUploadUtil class. You should only create the directory if it doesn't exist:

public static void saveFile(String uploadir, String fileName, MultipartFile multipartFile) throws IOException {
    Path uploadPath = Paths.get(uploadDir);
    if (!Files.exists(uploadPath)) {
        Files.createDirectories(uploadPath);
    }
    try (InputStream inputStream = multipartFile.getInputStream()) {
        Path filePath = uploadPath. resolve(fileName);
        System.out.printIn(filePath.toFile()-getAbsolutePath()+"File Path*******");
        Files.copy(inputStream, filePath, StandardCopyOption.REPLACE_EXISTING);
    } catch (IOException ioe) {
        throw new IOException("Could not save image file: " + fileName, ioe);
    }
}
