/**
 * @作者 赵昌峻
 * Apache Struts 2 was originally known as WebWork 2. 
 * After working independently for several years, 
 * the WebWork and Struts communities joined forces 
 * to create Struts2. This new version of Struts is simpler
 *  to use and closer to how Struts was always meant to be. 
 * 上面这段英文大体上说的是struts2的来龙去脉
 * 它是struts与webwork的结晶，可以说与struts1没有太大的关系
 * 
 * 所有Action都继承ActionSupport， 好像还有别的方法，我也还没搞懂，哈哈
 * 先这样理解吧！
 * 
 * 实现Preparable是可以在您的action中进行一些初始化之类的操作
