Wstawianie zdjęć do Posta SpringMVC Hibernate

Mam pytanie bo chce aby do postów były dodawane zdjęcia zrobiłam coś takiego i nie chce mi to zadziałać może ktoś coś podpowiedzieć?

Model Post:

@OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL, mappedBy = "post")
	   private List<Comment> comments= new ArrayList<>();
	
	@Lob
	@Column(name="images")
	private List<MultipartFile> images;
	
	public List<MultipartFile> getImages() {
		return images;
	}


	public void setImages(List<MultipartFile> images) {
		this.images = images;
	}

PostController:

@RequestMapping(value = "/savePost", method = RequestMethod.POST)
	public ModelAndView savePost(@ModelAttribute("post") Post post, 
			BindingResult result, HttpServletRequest request) {
		List<MultipartFile> files = post.getImages();
        List<String> fileNames = new ArrayList<String>();
        if (null != files && files.size() > 0)
        {
            for (MultipartFile multipartFile : files) {
 
                String fileName = multipartFile.getOriginalFilename();
                fileNames.add(fileName);
 
                File imageFile = new File(request.getServletContext().getRealPath("/images"), fileName);
                try
                {
                    multipartFile.transferTo(imageFile);
                } catch (IOException e)
                {
                    e.printStackTrace();
                }
            }}
	    postService.saveOrUpdate(post);
	    return new ModelAndView("redirect:/posts");
	}
	}

sql

CREATE TABLE `post` (
  `postid` int(11) NOT NULL AUTO_INCREMENT,
  `autor` varchar(45) NOT NULL,
  `tytul` varchar(512) NOT NULL,
  `opis` varchar(5000) NOT NULL,
  `images` blob NOT NULL,
  PRIMARY KEY (`postid`)
);

BLOB musi być w Javie typu byte[]. Na każdy image osobny rekord.
