how to update the data along with the multipart file

Question

I have created a form that has 2 file uploads and a few text content, it successfully uploads data in DB, when I'm trying to re-edit/update the same form. Either I'm getting bad request error if I use Multipart along with entity class. If I use multipart without entity it is creating new records but not updating the old records.

when add the entity class to this along with @RequestParam("file") MultipartFile file to save the file and other details iam getting an error while updating data.

Following is code:

@PostMapping("/update")
public String update(@RequestParam("bookPath") MultipartFile file, @RequestParam("bookCover") MultipartFile cover, 
        @RequestParam("bookName") String bookName, @RequestParam("totalpages") String totalpage,
        @RequestParam("bookAuthor") String BA,@RequestParam("bookPrice") String Bp,
        @RequestParam("bookPublicationDate") String bpd, @RequestParam("bookRating") String bookRating,
        @RequestParam("bookDesc") String Bdes, @RequestParam("ReadingAge") String readingAge,
        @RequestParam("AudioBook") String Ab,@RequestParam("isbn_num") String isbn,
        @RequestParam("status") String satus,
    @RequestParam("discount_option") String discount, @RequestParam("genres") String genras, 
    @RequestParam("dicsounted_price") String fixed_dis, 
    @RequestParam("percentge_value")  String percentage,  Book_dtls b)

Book_dtls is the entity class.
