</dependency>

配置文件

spring:

    host: 114.116.69.230
    port: 16379
    password:
    timeout: 120000
  session:
    store-type: redis #指定redis实现spring session
    timeout: 60 # Session 过期时间，单位s
    redis:
      flush-mode: immediate # Sessions 刷新模式
      namespace: spring-session # Namespace for keys used to store sessions.

编写代码

/**

@RestController
@RequestMapping(value = "/redis")
public class SessionController {

    @GetMapping(value = "/first")
    public Map<String, Object> firstResp(HttpSession session, String name) {
        Map<String, Object> map = new HashMap<>(1);
        TestVO vo = new TestVO();
        vo.setName(name);
        session.setAttribute("account", vo);
        map.put("sessionId", session.getId());
        return map;
    }

    @GetMapping(value = "/sessions")
    public Object sessions(HttpSession session) {
        Map<String, Object> map = new HashMap<>(2);
        map.put("sessionId", session.getId());
        map.put("message", session.getAttribute("account"));
        return map;
    }
}

拿Postman测试，启动两个服务，端口分别为8080，8081。在8080添加session，在8081获取session
