Struts2中的Result类型应用(action...etc跳转)
概况Result类型 是在Action执行完,一个结果返回后决定发生什么事的类。开发者可以自由的根据他们的应用和环境的需要创建自己的Result类型。例如在WebWork2中，Servlet和Velocity结果类型已经被创建用来显示web应用程序的画面。
注意: 所有的webwork内建的Result类型都实现了com.opensymphony.xwork.Result接口. 这个接口是所有action执行结果的通用接口,不管这个结果是用来显示一个网页还是产生一个email,发送一个JMS消息,等.
Result类型配置中定义了一些类,把它们映射为action配置中可以引用的名字. 也就是为这些类创建便于记忆的键-值对.
