有没有办法禁用java.util.logging并在以后将其启用？

Question

I'm using a library that logs a bunch of stuff that I don't want to log. It's using java.util.logging .

I also don't want to completely disable its logging since some of its logs are useful. Since the unwanted lines are logged only when I run a certain task, if there was a global way of disabling and enabling logging it would solve my problem.

Ideally something like:

disableLogging();
taskThatMakesUnnecessaryLogs();
enableLogging();

For a global impact you can use LogManager.reset() as your call to disable logging and to re-enable logging you can LogManager.readConfiguration() . However, there are some major flaws in what actually gets reloaded . The newer JDK9 method LogManager.updateConfiguration should be used instead.

If you know the logger name you can edit your logging.properties to modify the level of that offending logger or create a filter .

From code you can locate the logger and change it's level to OFF or something higher than the log messages you are seeing.

final Logger chatty = Logger.getLogger("somelogger");
final Level oldLevel = chatty.getLevel();
chatty.setLevel(Level.OFF);
try {
  taskThatMakesUnnecessaryLogs();
} finally {
  chatty.setLevel(oldLevel);
}
