**本文使用springboot实现session共享，基于spring session实现
想使用基于容器的session共享请搜索其他文章

本文不讲解基础环境搭建，需要使用idea、maven、springboot等相关知识点，不做介绍

 Hello,

 Hello,

整体项目结构与原来保持一致

原pom.xml中加入

        
            org.springframework.boot
            spring-boot-starter-redis
            1.3.8.RELEASE
            
        
        
            org.springframework.session
            spring-session-data-redis
        

将原来的application.properties改名了

加入：

spring:
  redis:
    database: 0
    host: ***
    port: 6379
    password: ***
    timeout: 0
    pool:
      max-active: 8
      max-wait: -1
      max-idle: 8
      min-idle: 0
    session:
      store-type: none

加入新文件RedisHttpSessionConfig.java

package com.xiang.springboot.demo.module1.config;

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

@Configuration
//maxInactiveIntervalInSeconds 默认是1800秒过期，这里测试修改为60秒
@EnableRedisHttpSession(maxInactiveIntervalInSeconds=60)
public class RedisHttpSessionConfig{

}

其他不用变

---------------2018.06.20 更新-----------------------------------------------

使用spring session之后原httpsessionListener的创建和销毁session的监听器会失效
处理方法：https://docs.spring.io/spring...

代码如下：

@Configuration
//maxInactiveIntervalInSeconds 默认是1800秒过期，这里测试修改为60秒
@EnableRedisHttpSession(maxInactiveIntervalInSeconds=180)
public class RedisHttpSessionConfig{

    @Bean
    public SessionEventHttpSessionListenerAdapter getSessionEventHttpSessionListenerAdapter(){
        List listeners = new ArrayList<>();
        listeners.add(getHttpSessionListener());
        return new SessionEventHttpSessionListenerAdapter(listeners);
    }

    @Bean
    public HttpSessionListener getHttpSessionListener(){
        return new MyHttpSessionListener();
    }
}
