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

添加依赖

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