How to stop Jsprit from printing logs to the console programmatically?

[Jason]

Firstly, I am very grateful for the amazing Jsprit toolkit developed by Stefan Schröder and improved by many kind coders, which is really easy to use and powerful to solve VRPs.

Now I have finished my programme but I need to stop Jsprit from printing logs to the console. I have tried many ways to do so, but failed. Is it possible to disable outputs programmatically?

Thanks and Best Regards.

Thank you for your kind words.

Put this for example into your resource folder. It configures jsprit's logger to only log error msg to STDOUT.

Best,
Stefan

Hi Stefan,

Thanks for the prompt reply.

I put the xml file into the /src folder, but the logger still prints. Please find a screenshot in the attached file. Perhaps the folder is wrong?

Thanks.

I do not know eclipse that well. You need to put the log4j2.xml file into the classpath. Maybe this helps? http://stackoverflow.com/questions/17944905/getting-log4j2-to-work-with-eclipse

Hi Stefan,

Thanks for your help. I actually has tried this solution, but no joy. My application based on Repast has to solve thousands VRPs in several minutes hopefully. Therefore, I try to disable printing for speed.

I find that in your XML file, the logger name of jsprit is "jsprit.core". So I added the following code before building a VRP:

List<Logger> loggers = Collections.<Logger>list(LogManager.getCurrentLoggers());
loggers.add(LogManager.getRootLogger());
for ( Logger logger : loggers ) {
   logger.setLevel(Level.OFF);
   System.out.println(logger.getName() +" ----- "+ logger.getLevel());
}
System.out.println("all loggers are off");

Logger jspritLogger = LogManager.getLogger("jsprit.core");
System.out.println("see Jsprit level: "+ jspritLogger.getLevel());
jspritLogger.setLevel(Level.OFF);
System.out.println("see Jsprit again: "+ jspritLogger.getLevel());
final VehicleRoutingProblem problem = vrpBuilder.build();

it prints:

It seems that, all loggers, including the root logger, are turned off successfully; the "jsprit.core" logger has no log level at the beginning, maybe it does not exist?

Howerver, the messages still appear even I turned off all these loggers. Maybe I should move these codes to somewhere proper?

Best Regards,

Jason

Hi Jason,

Sorry. Here, I cannot help you anymore. However, I guess that you do not gain much speed when turning off jsprit's logger (since the logger just prints infos, i.e. 10 lines or so). But still, I see that it is unsatisfying not to control the logger.

Best
Stefan
