Load Log4j2 configuration file programmatically

Question

I want to load Log4j2 XML configuration file programmatically from my application.

Tried this:

ConfigurationSource source = new ConfigurationSource()         


        

Answer 1

For the newest version of log4j, here is what should work for loading an external log4j2.xml:

String log4jConfigFile = System.getProperty("user.dir") + File.separator + "log4j2.xml";
ConfigurationSource source = new ConfigurationSource(new FileInputStream(log4jConfigFile));
Configurator.initialize(null, source);
