1.添加pom.xml依赖
org.springframework.boot
spring-boot-starter-data-redis
org.springframework.session
spring-session-data-redis
2.添加RedisSessionConfig.java配置
import org.springframework.context.annotation.Configuration;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;
/**
* @EnableRedisHttpSession 开启Redis Session缓存
* maxInactiveIntervalInSeconds: session过期时间
*
* */
@Configuration
@EnableRedisHttpSession(maxInactiveIntervalInSeconds = 30)
public class RedisSessionConfig {
}
3.添加application.yml配置
spring:
redis:
database: 0
host: localhost
port: 6379
password:
4.添加controller测试代码
@RestController
@RequestMapping("/user-info")
public class UserInfoController {
//测试
@GetMapping("/list2")
public Map setSession(HttpServletRequest request) {
Map map = new HashMap<>();
request.getSession().setAttribute("request Url", request.getRequestURL());
map.put("request Url", request.getRequestURL());
return map;
}
@GetMapping("/list3")
public Map getSession(HttpServletRequest request) {
Map map = new HashMap<>();
map.put("sessionIdUrl", request.getSession().getAttribute("request Url"));
map.put("sessionId", request.getSession().getId());
return map;
}
}
5.修改idea配置 启动多个节点项目
第一个节点正常启动就可以了，我application.yml里面配了8771
第二个节点需要改端口号，我这里设置8772
6.依次访问地址
http://127.0.0.1:8771/user/user-info/list2
http://127.0.0.1:8771/user/user-info/list3
http://127.0.0.1:8772/user/user-info/list3
发现：
两个节点获取到的SessionId是一致的，表明多节点实现Session共享
