How do I turn logging off using log4j?

Question

I am using a third-party library which has a log4j.xml configuration - what's the best way to turn off the logging?

Answer 1

Or directly from code:

Logger.getRootLogger().removeAllAppenders();

Answer 2

I think all that is required is to set the threshold parameter to OFF

<log4j:configuration threshold="OFF">
    <root>
        <priority value ="off" />
        <appender-ref ref="console" />
        <appender-ref ref="rolling-file" />
    </root>
</log4j:configuration>

Answer 3

With log4j.xml the minimal solution looks like this:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration threshold="off">
</log4j:configuration>

Note that in threshold="off", "off" must be in lower case.

Answer 4

You could also try setting the logging level to "Severe" if you only want to log game-breaking events.

Answer 5

Depends on configuration. Try something like:

<log4j:configuration>
    <root>
        <priority value ="off" />
        <appender-ref ref="console" />
        <appender-ref ref="rolling-file" />
    </root>
</log4j:configuration>
