使用LookupDispatchAction类犯的错误

    今天使用LookupDispatchAction时,由于编写的类继承LookupDispatchAction,同时也覆盖其execute()方法,结果导致自己编写的逻辑函数不起作用,把覆盖execute()方法的代码去掉即可实现同名按钮提交分别处理的效果,下面是代码:

 

JSP文件

 

<% @ page contentType = " text/html; charset=GBK "   %>
    <% @ include file = " taglib.jsp "   %>
    < html >
    < head >
    < title >
     jsp7
    </ title >
    </ head >
    < body bgcolor = " #ffffff " >
      < html:form action = " /processCheckoutAction.do " >
        < html:text property = " abc " >
        </ html:text >
        < html:submit property = " action " >< bean:message  
             key = " welcome.user " /></ html:submit >
        < html:submit property = " action " >< bean:message 
             key = " goodbye.user " /></ html:submit >
      </ html:form >
    </ body >
    </ html >
 

扩展的LookupDispatchAction

public   class  ProcessCheckoutAction  extends  LookupDispatchAction  ... {
    
    protected Map getKeyMethodMap()...{
        Map map=new HashMap();
        map.put("welcome.user","saveorder");
        map.put("goodbye.user","checkout");
        return map;
    }
    public ActionForward saveorder(ActionMapping mapping, 
                                 ActionForm form,
                                 HttpServletRequest request,
                                 HttpServletResponse response)...{
        System.out.println("saveorder");
        return (mapping.findForward("success1"));
    }
    public ActionForward checkout(ActionMapping mapping, 
                                 ActionForm form,
                                 HttpServletRequest request,
                                 HttpServletResponse response)...{
        System.out.println("checkout");
        return (mapping.findForward("success2"));
    }
}

Struts-config.xml相应的配置

 

< action  name ="untitled2ActionForm"  parameter ="action"   
 path ="/processCheckoutAction"  scope ="request"  
 type ="test.ProcessCheckoutAction"  validate ="true" >
       < forward  name ="success1"  path ="/jsp5.jsp"   />
       < forward  name ="success2"  path ="/jsp6.jsp"   />
  </ action >
