java - 尝试使用 logback 打印堆栈跟踪，但堆栈跟踪未打印

Question

我使用以下代码来打印 try catch block 中发生的任何异常，但是当异常发生时 logback 不会打印完整的堆栈跟踪，而是写入一行错误(没有明确说明)是什么导致了它。如何在 logback 输出中打印出完整的堆栈跟踪？

try catch 异常的 catch block

            try {
                // Create JMS objects
                context = cf.createContext();
                destination = context.createQueue("queue:///" + QUEUE_NAME);
                ((MQDestination)destination).setTargetClient(JMSC.MQJMS_CLIENT_NONJMS_MQ);
            } catch (Exception e) {
                // catch any exception occurred while trying to connect to the destination queue Manager
                e.printStackTrace();
                LOGGER.info(e.toString());
                return "Unable to connect to the destination queue Manager '"+QMGR +"'";
            
            }

登录错误输出:

21:18:10.748 [http-nio-8010-exec-4] INFO  com.mqMessageHandler.Webcontroller - com.ibm.msg.client.jms.DetailedJMSRuntimeException: JMSWMQ0018: Failed to connect to queue manager 'KAU.TST' with connection mode 'Client' and host name '192.168.1.25(1540)'.
Check the queue manager is started and if running in client mode, check there is a listener running. Please see the linked exception for more information.

e.toString() 将只打印错误消息。

如果您想打印完整的堆栈跟踪，请使用错误方法:

LOGGER.error("Exception occurred",e)

https://logging.apache.org/log4j/2.x/log4j-api/apidocs/org/apache/logging/log4j/Logger.html#error-java.lang.String-java.lang.Throwable-

如果您需要提取完整的堆栈跟踪，请从 apache common 查看以下 util 方法:

LOGGER.info("Exception : ",ExceptionUtils.getStackTrace(e));
