3:配置session共享,方式很多,這里用的redis的session共享(兼容jdk版本至少1.7):
    tomcat的lib包加commons-pool2-2.0.jar,jedis-2.5.2.jar,tomcat-redis-session-manager1.2.jar;
    tomcat配置文件context.xml,在標簽<Context>內添加配置:
        <Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
4:項目里面區分session的代碼:
    (1):放session的接口(執行一次);
    (2):取session數據(不斷刷新),看tomcat打印信息;
5:效果,http://www.nimenhaihaoma.com/redis3.2/getRedis.action (狂刷session值相同)
