public class RequestPartMethodArgumentResolver extends AbstractMessageConverterMethodArgumentResolver
@RequestPart
MultipartFile in conjunction with Spring's MultipartResolver abstraction
javax.servlet.http.Part in conjunction with Servlet 3.0 multipart requests
When a parameter is annotated with @RequestPart, the content of the part is
passed through an HttpMessageConverter to resolve the method argument with the
'Content-Type' of the request part in mind. This is analogous to what @RequestBody
does to resolve an argument based on the content of a regular request.
When a parameter is not annotated or the name of the part is not specified, it is derived from the name of the method argument.
Automatic validation may be applied if the argument is annotated with
@javax.validation.Valid. In case of validation failure, a
MethodArgumentNotValidException is raised and a 400 response status
code returned if DefaultHandlerExceptionResolver is configured.
