我尝试过以多种方式注册自定义异常Map器：

@Provider
public class ConstraintViolationMapper implements ExceptionMapper<ConstraintViolationException> {
    @Override
    public Response toResponse(ConstraintViolationException exception) {
        ...
    }
}

@Provider
public class ConstraintViolationMapper implements ExceptionMapper<ResteasyViolationException> {
    @Override
    public Response toResponse(ResteasyViolationException exception) {
        ...
    }
}

@Provider
public class ConstraintViolationMapper implements ExceptionMapper<ValidationException> {
    @Override
    public Response toResponse(ValidationException exception) {
        ...
    }
}

但所发生的只是resteasyviolationexceptionapper的默认行为。我的自定义异常apper从未被调用。我不知道还能尝试什么。
