在Action中要有相应的方法：
public class SubscriptionAction extends LookupDispatchAction {
public ActionForward save(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {}
public ActionForward back(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {}
public ActionForward recalculate(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {}
}
MappingDispatchAction
public class MappingDispatchAction extends DispatchAction
它的相应方法的执行由ActionMapping中parameter名决定,注意这里和LookupDispatchAction不同，LookupDispatchAction的相应方法的执行由ActionMapping中parameter属性决定。
struts-config.xml：
<action path="/createSubscription" type="org.example.SubscriptionAction" parameter="create">
<forward name="success" path="/createSubscription.jsp"/>
</action>
<action path="/editSubscription" type="org.example.SubscriptionAction" parameter="edit">
<forward name="success" path="/editSubscription.jsp"/>
</action>
<action path="/saveSubscription" type="org.example.SubscriptionAction" parameter="save"
name="subscriptionForm" validate="true" input="/editSubscription.jsp" scope="request">
<forward name="success" path="/savedSubscription.jsp"/>
</action>
<action path="/deleteSubscription" type="org.example.SubscriptionAction" name="subscriptionForm"
scope="request" input="/subscription.jsp" parameter="delete">
<forward name="success" path="/deletedSubscription.jsp"/>
</action>
<action path="/listSubscriptions" type="org.example.SubscriptionAction" parameter="list">
<forward name="success" path="/subscriptionList.jsp"/>
</action>
在Action中要有相应的方法：
public class SubscriptionAction extends MappingDispatchAction {
public ActionForward create(ActionMapping mapping, ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {}
public ActionForward edit(ActionMapping mapping, ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {}
public ActionForward save(ActionMapping mapping, ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {}
public ActionForward delete(ActionMapping mapping, ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {}
public ActionForward list(ActionMapping mapping, ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {}
}
然后可以通过这样的方法来访问你的程序：
http://localhost:8080/myapp/create.do
http://localhost:8080/myapp/edit.do
http://localhost:8080/myapp/save.do
http://localhost:8080/myapp/delete.do
http://localhost:8080/myapp/list.do
如果parameter中参数为空，则调用Action中的unspecified方法
