JAX-RS Generi c Exception Mapper не работает должным образом

0 голосов
/ 26 февраля 2020

Я использую джерси 2.29.

Я написал класс сопоставления исключений, чтобы перехватить все исключения. Но только некоторые из исключений попадают в ловушку.

Например, когда я выбрасываю свои пользовательские исключения, например BusinessException, ConfigException, тогда вызывается картограф. Но когда есть внутренняя ошибка сервера, она не вызывается. 

@Provider
public class GenericExceptionMapper implements ExceptionMapper<Throwable> {

    private static final Logger logger = LogManager.getLogger(GenericExceptionMapper.class);

    @Override
    public Response toResponse(Throwable exception) {

        ErrorMessage errorMessage = null;

        int errorCode = Status.INTERNAL_SERVER_ERROR.getStatusCode();

        if (exception instanceof BusinessException) {

            logger.debug("BusinessException:", exception);

            BusinessExceptionType businessExceptionType = ((BusinessException) exception).getErrorCode();

            switch (businessExceptionType) {

            case NOT_FOUND:

                errorCode = Status.NOT_FOUND.getStatusCode();
                break;

            case NOT_AUTHORISED:

                errorCode = Status.UNAUTHORIZED.getStatusCode();
                break;

            default:

                break;
            }

        } else if (exception instanceof ConfigException) {

            logger.fatal("ConfigException:", exception);

        } else if (exception instanceof WebApplicationException) {

            logger.error("WebApplicationException:", exception);

            Response response = ((WebApplicationException) exception).getResponse();
            errorCode = response.getStatus();
        }

        else {

            logger.fatal("GenericException:", exception);
        }

        errorMessage = new ErrorMessage(errorCode, exception.getMessage());
        return Response.status(errorCode).entity(errorMessage).type(MediaType.APPLICATION_JSON).build();
    }
}

Для Business Exception ошибка является правильной JSON: 

{
    "errorCode": 404,
    "errorMessage": "Not found"
}

Для любого другого сервера выдайте сообщение об ошибке не JSON:
