I'm using following code to print any exception occurs within the try catch block, but when the exception occurs logback doesn't print the full stack trace instead it write , a single line of error(which doesn't clearly say what caused it. How can I get the full stack trace printed out in the logback output?
Try catch block that captures the exception
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 "'";
}
log back Error out put :
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.
CodePudding user response：
e.toString() will just print the error message.
If you want to print the complete stacktrace , use the error method :
LOGGER.error("Exception occurred",e)
If you need to extract out full stack trace , checkout the following util method from apache common :
LOGGER.info("Exception : ",ExceptionUtils.getStackTrace(e));
