Question

如何在每次创建会话时初始化应用程序因为我面临的问题是当一个用户登录我的应用程序时，会创建新会话当另一个用户尝试在同一时间登录时，他看到第一个用户已登录，我需要知道如何为第二个用户初始化App而两个用户之间没有任何冲突我的班级是

@Component
public class MyHttpSessionEventPublisher extends HttpSessionEventPublisher {

    @Autowired
    LoginBean loginBean;
   @Override
   public void sessionCreated(HttpSessionEvent event) {
      super.sessionCreated(event);
      event.getSession().getId();
    //  loginBean.setLoginDao(null);
      System.out.println("Session id is : "+ event.getSession().getId());
      System.out.println(">>>>>>>>>>>>>>>>>>>>>>> session created <<<<<<<<<<<<<<<<<<<<<<<<<");
   }

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

      System.out.println(">>>>>>>>>>>>>>>>>>>>>>> session destroyed <<<<<<<<<<<<<<<<<<<<<<<<<");
   }

}

为了允许多个用户同时使用相同的用户名登录，我们可以使用http元素的并发控制功能，请参阅in the docs page 15：

<http>
    <session-management>
        <concurrency-control max-sessions=2 />
    </session-management>
</http>

通过将此添加到web.xml来注意常见的陷阱，否则并发登录将不起作用：

<listener>
    <listener-class>org.springframework.security.ui.session.HttpSessionEventPublisher</listener-class>
</listener>
