1 Conventional way

The following redisOperatoris a tool class, which simply encapsulates the redis api operation. If you are interested, you can download it at the following address:

CSDN download address : https://download.csdn.net/download/qq_15769939/15378282

1.1 Login

 // 登录的时候，token存入redis
  String uniqueToken = UUID.randomUUID().toString().trim();
  redisOperator.set("redis_user_token" + ":" + userId,uniqueToken);

1.2 Exit

 // 退出的时候，redis中移除token
  String uniqueToken = UUID.randomUUID().toString().trim();
  redisOperator.del("redis_user_token" + ":" + userId);

2 springSession way

2.1 Introduce dependencies

<dependency>
  <groupId>org.springframework.session</groupId>
  <artifactId>spring-session-data-redis</artifactId>
</dependency>
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-security</artifactId>
</dependency>

2.2 Configure storage type

spring:
	session:
		store-type: redis

2.3 boot configuration

@SpringBootApplication(exclude = {SecurityAutoConfiguration.class}) // 去除安全自动装配
@EnableRedisHttpSession // 开启使用redis作为spring session

2.4 Sample code

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

/**
 * 类文件: TestController
 * <p>
 * <p>
 * 类描述：测试控制层
 * <p>
 * 作     者： AusKa_T
 * <p>
 * 日     期： 2021/1/20 0010
 * <p>
 * 时     间： 20:19
 * <p>
 */
@RestController
public class TestController {
    
    

    @GetMapping("/setSession")
    public Object setSession(HttpServletRequest request) {
    
    
        HttpSession session = request.getSession();
        session.setAttribute("userInfo","new User");
        session.setMaxInactiveInterval(3600);
        session.getAttribute("userInfo");
//        session.removeAttribute("userInfo");
        return "ok";
    }
