struts之MappingDispatchAction的使用
jsp:<%--这里根据action的不同值（与struts-config.xml中path值对应）调用不同的方法--%><%--<html:form action="/mapDelete.do">--%><%--<html:form action="/mapSave.do">--%><html:form action="/mapSearch.do">age : <html:text property="age"/><html:errors property="age"/><br/>name : <html:text property="name"/><html:errors property="name"/><br/><input type="submit" name="method" value="search"/> </html:form>
action:
public class MapAction extends MappingDispatchAction {...public ActionForward saveAction(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) {MapForm mapForm = (MapForm) form;// TODO Auto-generated method stubSystem.out.println("MapAction...save(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)");return mapping.findForward("succ");}public ActionForward deleteAction(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) {MapForm mapForm = (MapForm) form;// TODO Auto-generated method stubSystem.out.println("MapAction...delete(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)");return mapping.findForward("succ");}public ActionForward searchAction(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) {MapForm mapForm = (MapForm) form;// TODO Auto-generated method stubSystem.out.println("MapAction...search(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)");return mapping.findForward("succ");}
struts-config.xml
<action attribute="mapForm" input="/jsp/map.jsp" name="mapForm" path="/mapSave" parameter="saveAction" scope="request" type="com.zhangl.struts.action.MapAction"> <forward name="succ" path="/jsp/succeed.jsp"></forward> </action> <action attribute="mapForm" input="/jsp/map.jsp" name="mapForm" path="/mapDelete" parameter="deleteAction" scope="request" type="com.zhangl.struts.action.MapAction"> <forward name="succ" path="/jsp/succeed.jsp"></forward> </action> <action attribute="mapForm" input="/jsp/map.jsp" name="mapForm" path="/mapSearch" parameter="searchAction" scope="request" type="com.zhangl.struts.action.MapAction"> <forward name="succ" path="/jsp/succeed.jsp"></forward> </action>
DispatchAction继承Action
LookupDispatchAction MappingDispatchAction都是继承DispatchAction
三者都可以实现一个action类对应多个应用
struts-config.xml中
DispatchAction一个配置
LookupDispatchAction一个配置
MappingDispatchAction多个配置
parameter＝“”前两者对应为参数名，第三者为方法名。
继承LookupDispatchAction的action需覆盖方法protected Map getKeyMethodMap()
并配置ApplicationResources.properties。
ie地址栏
DispatchAction显示方法名
LookupDispatchAction MappingDispatchAction隐藏方法名
