Do some cleanup during server shutting down (Spring app)

To do some work when we forcly stop the web server (wildfly,tomcat etc.)

We need to create a cleanup class which extends ContextCleanupListener which is provided from spring 3+.

Follow the below steps to do some cleanup during server being stopped.

Step-1 Create the cleanup class ApplicationCleanUpListener.java

package com.test;


import org.springframework.web.context.ContextCleanupListener;
import javax.servlet.ServletContextEvent;
import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;


public class ApplicationCleanUpListener extends ContextCleanupListener {
    @Override
    public void contextDestroyed(ServletContextEvent event) {

        //do some cleanup task
        System.out.print("Server is shutting down.....");
    }
}

Step-2

put these lines to web.xml

  com.test.ApplicationCleanUpListener
