Question

在我的Jax-Rs（Jersey + Jetty）应用程序中，我已经为响应添加了一些自定义标头，以便我可以在客户端使用它们。我正在使用ResponseBuilder来实现这一目标。

     @Provider
public class CustomExceptionMapper implements ExceptionMapper<CustomException> {

    private static final Logger LOGGER = LoggerFactory.getLogger(CustomExceptionMapper.class);

    @Context
    private HttpHeaders headers;


    @Override
    public Response toResponse(CustomException exception) {

        String errorKey = null;
        String errorArgs[] = null;

        // log stack trace
        LOGGER.error("An error occurred during the operation.", exception);
        if (exception instanceof MetadataServerException) {
                errorKey = ExceptionMapperUtil.checkForDBException(exception.getCause());
            if (errorKey != null) {
                return Response.status(Response.Status.INTERNAL_SERVER_ERROR)
                        .entity(MessageSourceUtils.getMessage(errorKey, errorArgs, ExceptionMapperUtil.getLocale(headers))).type(MediaType.TEXT_PLAIN).build();
            }
        }

        if(ErrorCodes.INTERNAL_SERVER_ERROR.equals(exception.getMessageKey()) && 
                (exception.getMessageArguments() == null || exception.getMessageArguments().length==0) ){
            exception.setMessageArguments(new Object[]{"while executing the operation"}); 

        }
        // prepare response to be sent to client
        return Response.status(ResponseCodeMapper.mapToStatusCode(exception)).
                entity(exception.getMessage(ExceptionMapperUtil.getLocale(headers))).
                type(MediaType.TEXT_PLAIN).header("errorCode", exception.getMessageKey()).
                build();
    }
}

而且，我已经确认响应对象正在构建正确。但是，由于某种原因，返回的响应不包含我的自定义标头。关于出了什么问题的任何线索？

客户标题不会出现在响应中
