/**
 * @作者 趙昌峻
 * 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. 
 * 上面這段英文大體上說的是struts2的來龍去脈
 * 它是struts與webwork的結晶，可以說與struts1沒有太大的關系
 * 
 * 所有Action都繼承ActionSupport， 好像還有別的方法，我也還沒搞懂，哈哈
 * 先這樣理解吧！
 * 
 * 實現Preparable是可以在您的action中進行一些初始化之類的操作
