8.controller

  1. package com.yl.securitydemo.controller;
  3. import org.springframework.beans.factory.annotation.Value;
  4. import org.springframework.web.bind.annotation.GetMapping;
  5. import org.springframework.web.bind.annotation.RestController;
  7. import javax.servlet.http.HttpSession;
  9. @RestController
  10. public class HelloController {
  12.     @GetMapping("/hello")
  13.     public String hello() {
  14.         return "hello";
  15.     }
  16.     @Value("${server.port}")
  17.     Integer port;
  19.     @GetMapping("/get")
  20.     public String get(HttpSession session) {
  21.      return session.getAttribute("name") + ":" + port;
  22.     }
  24.     @GetMapping("/set")
  25.     public String set(HttpSession session){
  26.         session.setAttribute("name","yl");
  27.         return String.valueOf(port);
  28.     }
  29. }

9.测试

1.打包项目，并且以8080和8081两个端口号启动两个实例

2.在客户端A登录admin账号，并且访问8080端口的hello接口

3.在客户端B再登录admin账号，访问8081端口的hello接口，登录发现账号已经登录了，成功限制用户的登录个数为1
