How do I reconfigure log4j2 in code with a specific configuration file?

 

See the below example. Be aware that this LoggerContext class is not part of the public API so your code may break with any minor release.

1. // import org.apache.logging.log4j.core.LoggerContext;
2.  
3. LoggerContext context = (org.apache.logging.log4j.core.LoggerContext) LogManager.getContext(false);
4. File file = new File("path/to/a/different/log4j2.xml");
5.  
6. // this will force a reconfiguration
7. context.setConfigLocation(file.toURI());
