WebApp ServletContext 초기화 및 소멸

웹서버의 최초 구동시와 정지시에 수행하게 되는 클래스가 있다

ServletContextListener.java

이를 이용하여 서버 시작시나 정지시에 수행해야 할 작업을 정의할 수 있다

import javax.servlet.ServletContextEvent;  
import javax.servlet.ServletContextListener;

public class CompileListener implements ServletContextListener {  
 
    private ServletContext context = null;  
 
    /* 
     * This method is invoked when the Web Application has been removed and is 
     * no longer able to accept requests 
     */ 
 
    public void contextDestroyed(ServletContextEvent event) {  
          
        // Output a simple message to the server's console  
        System.out.println("The Simple Web App. Has Been Removed");  
        this.context = null;  
 
    }
