Submit a form including image using spring mvc restful service

I want to implement a restful service using spring mvc, front-end is pure javascript.

The restful service is submitting a basic form including an image. Can I use Java Image type for the DTO? Something like this:

@Controller
public class PersonController {
@RequestMapping(value = "xxx/yyy", method = RequestMethod.POST)
public void submitForm(@RequestBody PersonDto personDto) {
    String name = personDto.getName();
    int age = personDto.getAge();
    Image image = personDto.getImage();
    service.save(xxxx);
}
}

@XmlRootElement
public class PersonDto {
    private String name;
    private int age;
    ....
    private Image image;
}

Could I just do something like above without using MultipartFile to upload an image? I am not sure when the request coming, the actual image can be converted to a Java Image type automatically by Spring MVC?
