Log4j 2 can reconfigure itself when its configuration file changes by using the monitorInterval attribute, for example:
<Configuration name="ConfigTest" status="ERROR" monitorInterval="5"> See https://logging.apache.org/log4j/2.x/manual/configuration.html For programmatic reconfiguration, you can use org.apache.logging.log4j.core.config.Configurator. I hope that gives you a place to start.
