Answer 1

As said dknight @RequestBody means use of JSON or XML data with maps your DTO bean. In case of MultipartFile you can't use JSON data so you can't use @RequestBody. Try with @ModelAttribute annotation.

Working sample :

@PostMapping("/promoters")
@Timed
public ResponseEntity createPromoter(@ModelAttribute PromoterDTO promoterDTO) throws URISyntaxException { ... }

With PromoterDTO like this :

    public class PromoterDTO implements Serializable {

        private Long id; 

        private String name;

        private String address;

        private MultipartFile logo;
    }
