Disabling Log4J Output in Java

Question

How can one quickly turn off all Log4J output using a log4j.properties file?

Answer 1

Set level to OFF (instead of DEBUG, INFO, ....)

Answer 2

If you want to turn off logging programmatically then use

List<Logger> loggers = Collections.<Logger>list(LogManager.getCurrentLoggers()); loggers.add(LogManager.getRootLogger()); for ( Logger logger : loggers ) {     logger.setLevel(Level.OFF); }
