问题 I have a custom exception class annotated to return a given HttpStatus : @ResponseStatus(value=HttpStatus.BAD_REQUEST, reason="Invalid parameter") public class BadRequestException extends RuntimeException { public BadRequestException(String msg) { super(msg); } } This works when I throw a BadRequestException from my controller but the reason is always "Invalid parameter" of course.
