org.apache.struts.actions.DispatchAction, 子类
org.apache.struts.actions.LookupDispatchAction, 子类
org.apache.struts.actions.MappingDispatchAction, 子类
DispatchAction, LookupDispatchAction, MappingDispatchAction都是l承的Actionc?
DispatchAction
定义
public abstract class DispatchAction extends Action
q是一个抽象的Action,它会Ҏrequest 中的parameter来执行相应的Ҏ。通个q个Actioncd以将不同的Action集中C个Action文g中来?/p>
Struts-config.xml:
<action path="/saveSubscription" type="org.apache.struts.actions.DispatchAction" name="subscriptionForm" scope="request" input="/subscription.jsp" parameter="method"/>
在Action中要有相应的Ҏ:
Public class demoAction extends DispatchAction{
public ActionForward delete(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception
public ActionForward insert(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception
public ActionForward update(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception
}
你就可以通过q样的方法来讉K你的E序:
http://localhost:8080/myapp/saveSubscription.do?method=update
如果parameter中参CؓI，则执行Action中unspecifiedҎ
LookupDispatchAction
public abstract class LookupDispatchAction extends DispatchAction
通过q个Action抽象cȝ承DispatchActionQ它的相应方法的执行?ActionMapping中parameter属性决定。它适合在一个form中有很多按钮Q按不同的按钮则执行不同的操作?/p>
struts-config.xml:
<action path="/test"
type="org.example.MyAction"
name="MyForm"
scope="request"
input="/test.jsp"
parameter="method"/>
ApplicationResources.properties:
button.add=Add Record
button.delete=Delete Record
JSP:
<html:form action="/test">
<html:submit property="method">
<bean:message key="button.add"/>
</html:submit>
<html:submit property="method">
<bean:message key="button.delete"/>
</html:submit>
</html:form>
在Action 中必d现getKeyMethodMap:
protected Map getKeyMethodMap() {
Map map = new HashMap();
map.put("button.add", "add");
map.put("button.delete", "delete");
return map;
}
public ActionForward add(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
// do add
return mapping.findForward("success");
}
public ActionForward delete(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
// do delete
return mapping.findForward("success");
}
MappingDispatchAction
public class MappingDispatchAction extends DispatchAction
它的相应Ҏ的执行由 ActionMapping中parameter名决?注意q里和LookupDispatchAction不同QLookupDispatchAction的相应方法的执行?ActionMapping中parameter属性决定，
struts-config.xml:
<action path="/saveSubscription"
type="org.example.SubscriptionAction"
name="subscriptionForm"
scope="request"
input="/subscription.jsp"
parameter="method"/>
Action:
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
for which you would create corresponding <action> configurations that reference this class:
<action path="/createSubscription"
type="org.example.SubscriptionAction"
parameter="create">
<forward name="success" path="/editSubscription.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>
DispatchAction,LookupDispatchAction,MappingDispatchAction
1) DispatchAction是在struts-config中用parameter参数配置一个表单字D名,q个字段的值就是最l替代execute被调用的Ҏ. 例如parameter="method"而request.getParameter("method")="save"Q其?save"是MethodName。struts的请求将Ҏparameter被分发到"save"或?edit"或者什么。但是有一点，save()或者edit(){方法的声明和execute必须一模一栗?/p>
2) LookupDispatchActionl承DispatchAction, 用于对同一个页面上的多个submit按钮q行不同的响应。其原理是，首先用MessageResource按钮的文本和ResKey相关联，例如button.save=保存Q然后再复写getKeyMethodMap(), ResKey和MethodName对应h, 例如map.put("button.save", "save"); 光|方法和DispatchAction是一L, 使用时要q么?
3) MappingDispatchAction?.2新加? 也承自DispatchAction. 它实现的功能和上面两个区别较? 是通过struts-config.xml多个action-mapping映射到同一个Actioncȝ不同Ҏ? 典型的配|就?
然后UserActionl承MappingDispatchActionQ其中有Q?br />
public ActionForward save(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception
public ActionForward edit(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception
{方?/p>
可以看到, 不管怎么变化, 其实q些c都是把executel分解开, 不管是save, editq是其他什么方? 其实都是和原来的execute是等L, save和edit之间没有M直接的关p? 而事实呢Q它们是同一个业务模型的两种不同操作?我觉得这是一个问题，对于save和editq两U请? 我后台逻辑有可能只是调用service的方法那一句不一P其他代码是完全一致的(例如错误处理, 日志记录{?。因此我惛_了这个小东西Q在executeҎ内部q行局部分?/p>
2.打开eclipse,先徏立一个Web目.然后把这个urlrewrite-3.0.4.jar复制到项目重中的lib文g下面.
