java – 无法处理部件,因为未提供多部件配置

我写了一个简单的控制器来上传文件：

@RestEndpoint
public class ImageController {
    @Autowired
    GridFstemplate mTemplate;

    @RequestMapping(value = "images",method = RequestMethod.POST)
    public @ResponseBody String testPhoto(@RequestParam String name,@RequestParam String directory,@RequestParam multipartfile file) throws IOException {

        if(!file.isEmpty()){
            final byte[] bytes = file.getBytes();
            InputStream inputStream = new ByteArrayInputStream(bytes);
            mTemplate.store(inputStream,"name");

            return "uploaded photo";
        }

        return "Failed";
    }

} 

@RestEndpoint注释是：

@Target({ ElementType.TYPE })
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Controller
public @interface RestEndpoint
{
    String value() default "";
}

我的ContextCOnfiguration类是：

@Configuration
@EnableWebMvc
@ComponentScan(
    basePackages = "com.questter.site",useDefaultFilters = false,includeFilters =
    @ComponentScan.Filter({RestEndpoint.class,RestEndpointAdvice.class})
)
public class RestServletContextConfiguration extends WebMvcConfigurerAdapter {
    @Bean
    public CommonsMultipartResolver multiPartResolver(){

        CommonsMultipartResolver resolver = new CommonsMultipartResolver();
        return resolver;
    }
...
}
