java.lang.Object
  org.apache.logging.log4j.core.web.Log4jServletFilter

All Implemented Interfaces:

Filter

public class Log4jServletFilter
extends Object
implements Filter

This is responsible for the following:

• Clearing the logger context when the application has finished starting up.
• Setting the logger context before processing a request and clearing it after processing a request.
• Setting the logger context when the application is starting to shut down.

This filter is a once-per-request filter. It is capable of filtering all the different types of requests (standard, asynchronous, error, etc.) but will not apply processing if the filter matches multiple times on the same logical request.
