Spring + Shiro 项目 + HttpSessionListener 【调用springService问题】&【Session失效问题】
功能描述:
当用户退出(主动)或者关闭浏览器(session超时)的时候,利用本次登录Ip更新上次登录IP。有人可能要问,你在用户登录的时候记录不就行了。可是我有两个字段,一个为本次登录IP,另外一个为上次登录IP。当用户退出的时候,本次登录IP也就成了上次登录IP。
首先解决的问题是:在Listener里面访问Service。
因为是基于注解开发,将Listener扫描和将Service成员变量注解@Autowired是不能解决问题的。运行起来会报空指针。
public class UserLeaveListener implements HttpSessionListener { private UserService userService; @Override public void sessionCreated(HttpSessionEvent arg0) { // 记录访问日志:IP } @Override public void sessionDestroyed(HttpSessionEvent arg0) { System.out.println("---SessionListener---"); //调用 session.invalidate(); 后,在这个方法里仍然可以获取到属性值 ApplicationContext applicationContext = WebApplicationContextUtils.getWebApplicationContext( arg0.getSession().getServletContext()); userService = applicationContext.getBean(UserService.class); HttpSession session = arg0.getSession(); User user = (User) session.getAttribute("user"); System.out.println("user:" + user); //如果user不为空,代表超时退出。否则是主动退出 if(user != null){ System.out.println("用户超时退出:" + user.getUserName()); userService.updatePreIp(user.getUserId(), user.getUserCurIP()); }else{ System.out.println("用户已经退出"); } } }
核心代码便是
ApplicationContext applicationContext = WebApplicationContextUtils.getWebApplicationContext( arg0.getSession().getServletContext()); userService = applicationContext.getBean(UserService.class);
第二个问题:在我的登出Controller方法中,我调用
session.invalidate();
后的确能够进入listener,也成功执行了service方法,但是却爆了错。这个错不影响什么,但是看起来难受

看这句:
[org.apache.shiro.session.InvalidSessionException: java.lang.IllegalStateException: getAttribute: Session already invalidated]
可以知道这个shiro啊,他想找这个session玩,但是session已经不在了。经过查阅我猜整合了shiro之后,就得考虑shiro的感受了。那么shiro有没有退出的方法呢?
SecurityUtils.getSubject().logout();
原来有啊,我就在controller方法中把它也加上了。
运行成功之后,又报错了。
java.lang.IllegalStateException: invalidate: Session already invalidated
我很怀疑用了shiro之后,shiro就霸占了session。所以我就把session.invalidate去掉了
果然运行之后啥错误都没有了。
客户端地址:0:0:0:0:0:0:0:1 user:User [userId=14962441362734L7V7MF, userName=博美, ...] 用户主动退出:博美 ---SessionListener--- user:User [userId=14962441362734L7V7MF, userName=博美, ...] 用户超时退出:博美 ---SessionListener--- user:null 用户已经退出
这里说一下,虽然我们调用了让session失效的方法,但是等到session超时时间一到,会再次进入sessionListener中
