SpringBoot的Session并发控制

⒈是什么？

　　即控制业务系统中一个用户只能有一个Session

⒉解决方案

　　1.当这个用户在其它地方登录的时候，把之前的Session失效掉。

65     }

 4 import org.springframework.security.web.session.SessionInformationExpiredStrategy;

 6 import javax.servlet.ServletException;
 7 import java.io.IOException;

10     @Override
11     public void onExpiredSessionDetected(SessionInformationExpiredEvent sessionInformationExpiredEvent) throws IOException, ServletException {
12         sessionInformationExpiredEvent.getResponse().setContentType("application/json;charset=UTF-8");
13         sessionInformationExpiredEvent.getResponse().getWriter().write("并发登录！");
14     }
15 }

　　2.当这个用户已经登陆了，禁止在其它地方登录。
