PS:截止到2015-05-12前是不支持Tomcat8的,详情见官网:https://github.com/jcoleman/tomcat-redis-session-manager

前提:你已经部署了Redis,尚未学会的,可以移步这里:http://blog.csdn.net/caiwenfeng_for_23/article/details/45511007

其实很简单,就几个步骤: 
1.配置Tomcat的conf目录下的context.xml文件:

1> 单点Reids配置

    <!-- 
    Jedis save session
    -->
    <Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />        
    <Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager" 
        host="localhost" 
        port="6379" 
        database="0" 
        maxInactiveInterval="60"/>

 

2> Sentinel集群配置:

        <!-- Sentinel 配置 -->
     <Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />        
    <Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager" 
        maxInactiveInterval="60"
        sentinelMaster="mymaster"
        sentinels="127.0.0.1:26379,127.0.0.1:26380,127.0.0.1:26381,127.0.0.1:26382"
        />

2.添加jar

3.测试

1> 
存储Session:

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        System.out.println("hello");
           //取得Session对象
        HttpSession session=request.getSession(); 
        //设置Session属性
        for(int i=0;i<100000;i++){
            session.setAttribute("name"+i, "Magci_"+i); 
        }
    }

2>重启Tomcat:假如Session保存在tomcat下,重启后Session不存在;如果保存在Redis下,Tomcat重启对Session无影响

3>取出Session:

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        System.out.println("hello");
           //取得Session对象
        HttpSession session=request.getSession(); 
        //取出Session属性
        for(int i=0;i<100000;i++){
            System.out.println(session.getAttribute("name"+i));
        }
    }

注意事项:从Tomcat6开始默认开启了Session持久化设置,测试时可以关闭本地Session持久化,其实也很简单,在Tomcat的conf目录下的context.xml文件中,取消注释下面那段配置即可:

    <!-- Uncomment this to disable session persistence across Tomcat restarts -->
    <!--
    <Manager pathname="" />
    -->

详见这篇博客:Session持久化的实例分析
