web容器中用jmx监控hibernate sessionFactory

以tomcat为例，加入一个listner监听容器启动：

 

    <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。
