SessionListner 를 이용한 세션이벤트 감지하기

===========SessionListner.java========================

package com.martmunja.controller;

import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSessionListener;
import org.springframework.web.servlet.ModelAndView;

 

public class SessionListner implements HttpSessionListener{

 

@Override

public void sessionCreated(HttpSessionEvent arg0) {

 
// 세션 생성시 호출

HttpSession session = arg0.getSession();

long time = session.getCreationTime();

String id = session.getId();

System.out.println(time + "에 생성된 세션" + id);


}



@Override

public void sessionDestroyed(HttpSessionEvent arg0) {

// 세션 만료시 호출

HttpSession session = arg0.getSession();

long time = session.getCreationTime();

long last_time = session.getLastAccessedTime();

long now_time = System.currentTimeMillis();

String id = session.getId();

System.out.println((now_time - last_time) + "ms 만에 세션이 죽음"  + id);


}



}
