public class RequestResponseBodyMethodProcessor extends AbstractMessageConverterMethodProcessor
@RequestBody and handles return
values from methods annotated with @ResponseBody by reading and writing
to the body of the request or response with an HttpMessageConverter.
An @RequestBody method argument is also validated if it is annotated
with @javax.validation.Valid. In case of validation failure,
MethodArgumentNotValidException is raised and results in an HTTP 400
response status code if DefaultHandlerExceptionResolver is configured.
