session监听器

用于监听session销毁

当session销毁时改变数据库内用户登录状态

/**
 * session监听器
 */
public class SessionListener implements HttpSessionListener{


private UserLoginService service;
public SessionListener(){
String[] conf = {"conf/spring-mybatis.xml","conf/spring-mvc.xml"};
ApplicationContext ac = new ClassPathXmlApplicationContext(conf);
service = ac.getBean("userLoginService",UserLoginService.class);
}

public void sessionCreated(HttpSessionEvent hse) {

}

/**
* 监听session销毁，并记录用户登录状况
*/
public void sessionDestroyed(HttpSessionEvent hse) {
HttpSession session = hse.getSession();
User user = (User) session.getAttribute("User");
if(user!=null){
user.setLast_login_time(user.getLogin_time());
user.setLast_login_ip(user.getLogin_ip());
user.setIsOnline("N");
service.recordedLogin(user);
}
}


}
