Java – How to disable loggers of a class or of whole package


I am using Apache Commons Logging ™. For now I wanted to use SimpleLog implementation, but when I changed the level, loggers from the libraries came out. I want it to turn them off.

Is there a easy way to change log level for whole package (can Log4j do that)?

I have tried to set

in the property files to disable (setting to fatal is OK) foo logger, but it doesn't work (foo is a name of logger that appears in output : [INFO] foo - Message).

Best Solution

In Log4j you can specify a logging level for specified package, class or logger identified by string. You just simply write this in file:

log4j.logger.<your package> = DEBUG|INFO|OFF|WARN...
