Log4jServletContextListener

java.lang.Object
- org.apache.logging.log4j.web.Log4jServletContextListener

All Implemented Interfaces:

jakarta.servlet.ServletContextListener, java.util.EventListener
```
public class Log4jServletContextListener
extends java.lang.Object
implements jakarta.servlet.ServletContextListener
```
In environments older than Servlet 3.0, this initializer is responsible for starting up Log4j logging before anything else happens in application initialization. In all environments, this shuts down Log4j after the application shuts down.
