Question

我一直在 SpringBoot 中开发电子邮件服务，并且为了登录，我正在使用 slf4j 。该应用程序按预期工作，除了日志部分。在我的计算机上运行它时，日志记录运行良好。但是，一旦将其部署在服务器上，日志记录将按预期工作，直到发生异常。之后，将在每个日志语句中打印一个“ stacktrace”元素。 stacktrace来自发生的最后一个异常，直到下一个异常才改变。日志语句的级别是 INFO ， WARN 还是 ERROR 都没有关系。由于我无法重现它，而且我也不知道是什么原因导致了此问题，这使我非常沮丧。我已经搜索了谷歌和stackoverflow但没有运气。我找不到与此问题相关的任何帖子。以下是我在应用程序中使用的一些日志记录设置以及日志语句。

我还写了一个util Logging类，其中包含用于不同日志级别的包装器方法。

public class LoggingUtil {


    public static void logWarn(String message, EmailRequest emailRequest, Logger logger) {
        Map<String, String> identifierMap = getRequestIdentifiers(emailRequest);
        StringBuffer warnMessage = new StringBuffer(checkPunctuation(message));
        warnMessage.append(Constants.REQUEST_IDENTIFIERS);

        logger.warn(warnMessage.toString(), identifierMap.get(Constants.ORDERID),
                identifierMap.get(Constants.TEMPLATENAME),
                identifierMap.get(Constants.SESSIONID),
                identifierMap.get(Constants.STOREID));
    }

    /**

    public static void logInfo(String message, EmailRequest emailRequest, Logger logger) {
        Map<String, String> identifierMap = getRequestIdentifiers(emailRequest);
        StringBuffer infoMessage = new StringBuffer(checkPunctuation(message));

        infoMessage.append(Constants.REQUEST_IDENTIFIERS);

        logger.info(infoMessage.toString(), identifierMap.get(Constants.ORDERID),
                identifierMap.get(Constants.TEMPLATENAME),
                identifierMap.get(Constants.SESSIONID),
                identifierMap.get(Constants.STOREID));
    }

    public static void logInfo(String message, KafkaMessage kafkaMessage, Logger logger) {
        String sessionId = null;
        String clientOriginationId = null;
        String eventId = null;
        String eventName = null;
        String timeStamp = null;

        StringBuilder stringBuilder = new StringBuilder(checkPunctuation(message));
        stringBuilder.append(Constants.KAFKA_MESSAGE_IDENTIFIERS);

        if(kafkaMessage != null && kafkaMessage.getHeader() != null) {
            Header header = kafkaMessage.getHeader();
            sessionId = header.getSessionId();
            clientOriginationId = header.getClientOriginationId();
            eventId = header.getEventId();
            eventName = header.getEventName();
            timeStamp = header.getTimestamp();
        }

        logger.info(stringBuilder.toString(), sessionId, clientOriginationId, eventId, eventName, timeStamp);
    }

    /**

     * @param e
     */
    public static void logError(String message, EmailRequest emailRequest, Exception e, Logger logger) {
        Map<String, String> identifierMap = getRequestIdentifiers(emailRequest);

        StringBuffer errorMessage = new StringBuffer(checkPunctuation(message));
        errorMessage.append(Constants.REQUEST_IDENTIFIERS);

        logger.error(errorMessage.toString(), identifierMap.get(Constants.ORDERID),
                identifierMap.get(Constants.TEMPLATENAME),
                identifierMap.get(Constants.SESSIONID),
                identifierMap.get(Constants.STOREID), e.getMessage(), e);
    }

    /**
     * This method extracts the request identfiers from email request object

     */
    private static Map<String, String> getRequestIdentifiers(EmailRequest emailRequest) {
        String templateName = emailRequest != null ? emailRequest.getTemplateName() : null;
        String orderId = null;
        String sessionId = null;
        String storeId = null;

            EmailVars emailVars = emailRequest.getEmailVars();
            orderId = emailVars.getTemplateVariable(Constants.ORDERID);

            storeId = emailVars.getTemplateVariable(Constants.STOREID);
        }
        Map<String, String> identifierMap = new HashMap<String, String>();

        identifierMap.put(Constants.ORDERID, orderId);
        identifierMap.put(Constants.SESSIONID, sessionId);
        identifierMap.put(Constants.STOREID, storeId);

        return identifierMap;
    }

    /**

        //checking if the message ends with a period '.'

            stringBuilder.append(". ");
        }

        return stringBuilder.toString();
    }
}

我怀疑包装器方法可能是罪魁祸首，因为我将记录器实例从发生异常的类传递给包装器方法。我不确定。感谢您的帮助，谢谢。
