web器皿中用jmx监控hibernate sessionFactory

web容器中用jmx监控hibernate sessionFactory
<listener> <description>ServletContextListener</description> <listener-class>com.my.listener.StartupListener</listener-class> </listener>

?Listener中的内容：

@Override    public void contextInitialized(ServletContextEvent sce) {        SessionFactory sf = HibernateUtil.getSessionFactory();        MBeanServer ms = ManagementFactory.getPlatformMBeanServer();                Hashtable tb = new Hashtable();        tb.put("type", "statistics");        tb.put("sessionFactory", "myHibernateApp");        try {            ObjectName on = new ObjectName("hibernate",tb);            StatisticsService mBean = new StatisticsService();            mBean.setSessionFactory(sf);            mBean.setStatisticsEnabled(true);            ms.registerMBean(mBean, on);        } catch (Exception ex) {            Logger.getLogger(StartupListener.class.getName()).log(Level.SEVERE, null, ex);        }     }

tomcat启动需要添加一行jvm参数：-Dcom.sun.management.jmxremote.port=1090?-Dcom.sun.management.jmxremote.ssl=false?-Dcom.sun.management.jmxremote.authenticate=false

用来启动tomcat的jmx服务管理。

启动后通过jconsole访问tomcat的jmx监听端口。
