Configure the root logger with java logging API

Question

how can I configure the behaviour of the root logger in the logging api? I don't want to configure the behaviour of each logger separately, instead it would be very convenient if I have a single property file where I can set the behaviour of all loggers.

Answer 1

Use the following to get the root logger:

Logger system = Logger.getLogger("");

You can now access the root logger as any other logger.

In my case I was willing to make it quiet. I succeeded to do it with the following code:

private static void setLevel(Logger pLogger, Level pLevel) {
    Handler[] handlers = pLogger.getHandlers(); 
    for (Handler h : handlers) {
        h.setLevel(pLevel);
    }
    pLogger.setLevel(pLevel);
}

...

setLevel(system, Level.OFF);

Hope this helps.
