DispatchAction的用法

写个Action继承DispatchAction：

public class DoNothingAction extends DispatchAction {

public ActionForward add(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) {
  System.out.println("ADD method was invoked.");
  return mapping.findForward("index");
}

public ActionForward update(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) {
  System.out.println("UPDATE method was invoked.");
  return mapping.findForward("index");
}
}

struts-config.xml中配置：

<action path="/doNothing" type="com.yourcompany.struts.action.DoNothingAction"
   parameter="method"
   scope="request">
   <forward name="index" path="/index.jsp"></forward>
   </action>

页面调用：

<a href="doNothing.do?method=add">Execute ADD method</a><br>
   <a href="doNothing.do?method=update">Execute UPDATE method</a>
