//This was my code to handle the image and data
public ResponseEntity addProduct( Product product, MultipartFile file) {

    Authentication authentication= SecurityContextHolder.getContext().getAuthentication();

    String userName= authentication.getName();
    Users admin = userRepository.findByUsername(userName);

    try {
        if (!file.isEmpty()) {
            byte[] imageData = file.getBytes();
            product.setImage(imageData);
            productRepository.save(product);
            ProductOwnerShip productOwnerShip=new ProductOwnerShip();
            productOwnerShip.setProduct(product);
            productOwnerShip.setUser(admin);
            productOwnerShipRepository.save(productOwnerShip);
        } else {
            return new ResponseEntity<>("Error: No image file uploaded", HttpStatus.BAD_REQUEST);
        }

        // Process and save the product with the image in your database



        return new ResponseEntity<>("Product added successfully", HttpStatus.OK);
    } catch (IOException e) {
        e.printStackTrace();
        return new ResponseEntity<>("Error uploading image", HttpStatus.INTERNAL_SERVER_ERROR);
    }

}
