springboot将session存储在redis中，可以实现session共享

添加依赖

        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-data-redisartifactId>
        dependency>
        
        <dependency>
            <groupId>org.springframework.sessiongroupId>
            <artifactId>spring-session-data-redisartifactId>
        dependency>

写一个配置类

package com.jf.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.session.data.redis.config.ConfigureRedisAction;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;

@Configuration
@EnableRedisHttpSession(maxInactiveIntervalInSeconds=60*30)//设置session过期时间,默认也是1800秒
public class HttpSessionConfig {

    //enableRedisKeyspaceNotificationsInitializer
    @Bean
    public static ConfigureRedisAction configureRedisAction() {
        return ConfigureRedisAction.NO_OP;
    }
}

session存取，和以前一样不用变化，还是在httpSession中操作。

redis中存的值
