spring security 없이 중복 로그인 방지

http://www.egovframe.go.kr/wiki/doku.php?id=egovframework:com:v3:cmm:multilogin

 

타임 아웃 설정도 해야 한다.

package com.examples;
import javax.servlet.http.HttpSessionEvent;

import org.springframework.security.web.session.HttpSessionEventPublisher;


public class MyHttpSessionEventPublisher extends HttpSessionEventPublisher {

   @Override
   public void sessionCreated(HttpSessionEvent event) {
      super.sessionCreated(event);
   }

   @Override
   public void sessionDestroyed(HttpSessionEvent event) {
      //do something
      super.sessionDestroyed(event);
   }

}

and then register this listener in your web.xml like this:

<listener>
    <listener-class>com.examples.MyHttpSessionEventPublisher</listener-class>
 </listener>
