@EnableRedisHttpSession来开启spring session支持

spring.redis.host=localhost
spring.redis.port=6379
spring.redis.password=123

@RestController
public class RedisController {


    @RequestMapping("/first")
    public Map<String,Object> getMap(HttpServletRequest request){
        Map<String,Object> map=new HashMap<>();
        map.put("url",request.getRequestURL());
        return map;
    }


    @RequestMapping("/sessions")
    public Map<String,Object> getSession(HttpServletRequest request){
        Map<String,Object> map=new HashMap<>();
        map.put("sessionId",request.getSession().getId());
        return map;
    }
}

    @Configuration  
    @EnableRedisHttpSession  
    public class RedisSessionConfig {  
    }  

项目启动两次 端口号分别是8080，8081

访问8080 端口

获取session

在获取8081端口session和8080端口session一致 已经实现session共享
