}

Answer 1

You can't send @RequestBody along with MultipartFile and you don't even need it in your case. Send only MultiPartFile.

public Alian Saving(@RequestParam("file") MultipartFile file) {
    Alian alian = new Alian();
    alian.setPic(file.getBytes());
    alian.setAname(file.getOriginalFilename());
    return repo.save(alian);
}

Answer 2

You can use multipart/form-data .

See https://www.getpostman.com/docs/v6/postman/sending_api_requests/requests#form-data

Answer 3

Ensure that you are not adding content-type manually.

There is no need to add a content-type header manually. You are overriding the value set by Postman. Just select form-data in POST request and send your request to see if it works.
