前提:你已经部署了Redis,还没有学会的,能够移步这里:http://blog.csdn.net/caiwenfeng_for_23/article/details/45511007 java

其实很简单,就几个步骤:
1.配置Tomcat的conf目录下的context.xml文件: github
<!-- 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: redis
<!-- 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" />
3.测试 tomcat
1>
存储Session: 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;若是保存在Redis下,Tomcat重启对Session无影响 测试
3>取出Session: this
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,测试时能够关闭本地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便可: spa
<!-- Uncomment this to disable session persistence across Tomcat restarts --> <!-- <Manager pathname="" /> -->
