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 a 400 response status code if DefaultHandlerExceptionResolver
is configured.
