IllegalStateException: Unable to process parts as no multi-part configuration has been provided

Есть у меня контроллерный метод:

@PutMapping(value = "/mail",
            consumes = MediaType.MULTIPART_FORM_DATA_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
    public ResponseEntity<Report> mail(@RequestPart("data") MailMessageDto dto,
                                       @RequestPart(value = "attachments", required = false) List<MultipartFile> attachments) {

В него должны приходить два мультипарта - JSON (файлом, здесь он "data") и несколько файлов (здесь они "attachments").

Я добавил резолвер:

@Configuration
public class ApplicationConfig {
    @Bean
    public CommonsMultipartResolver multipartResolver() {
        CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
        multipartResolver.setMaxUploadSize(50000000);
        multipartResolver.setMaxUploadSizePerFile(5000000);
        return multipartResolver;
    }
}

Зависимости:

compile group: 'commons-fileupload', name: 'commons-fileupload', version: '1.3.3'
compile group: 'commons-io', name: 'commons-io', version: '2.6'

Вроде, должно работать, но нет:
