这个简单的Mbean只有一个属性和一个方法，StardBeanDemoMain 为调用类，
main方法中调用下面三个方法，代码中都有详细的注释：
sbean.doRegistBean();
sbean.doManageBean();
sbean.regHtmlAdaptor();
运行后，可以看到控制台打印的信息，
register StandMbean sucess..
Attribute:state -init value
Attribute:state 2 -new state
My service start.....
由于启动了HtmlAdaptor的服务，所以程序一直处于运行状态，（HtmlAdaptor是sun jmx实现自带的一个适配器）测试可以在浏览器中访问：
http://localhost:8082 就可以在浏览器中管理mbean了，在List of MBean operations下面按startService 按钮，可以看到控制台打出的信息，说明startService方法被调用了。
