    Add the consumer type to your request mapping .it should work fine.

    @POST
@RequestMapping("/upload")
public ResponseEntity upload(@RequestParam("file") MultipartFile file,consumes = "multipart/form-data") 
{
    if (file.isEmpty()) {
        return new ResponseEntity(HttpStatus.BAD_REQUEST);
    } else {
        //...
    }
}
