Struts 1 学习笔记-4-4（Struts中ActionForward的测试）

这次主要测试了ActionForward的redirect 属性以及静态和动态的ActinForward

1.struts-config.xml：

<? xml version="1.0" encoding="ISO-8859-1"  ?>

<! DOCTYPE struts-config PUBLIC
          "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
          "http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd" >

< struts-config >
    
     < form-beans >
         < form-bean  name ="loginActionForm"  type ="com.ycringfinger.struts.LoginActionForm" ></ form-bean >
     </ form-beans >
    
     < global-forwards >
         < forward  name ="login"  path ="/login.jsp"  redirect ="true" ></ forward >
     </ global-forwards >
    
     < action-mappings >
         < action  path ="/login"  type ="com.ycringfinger.struts.LoginAction"  name ="loginActionForm"  scope ="request" >
             < forward  name ="success"  path ="/login_success.jsp" ></ forward >
             < forward  name ="error"  path ="/login_error.jsp" ></ forward >
         </ action >
         < action  path ="/mustlogin"  type ="com.ycringfinger.struts.MustLoginAction"  scope ="request" >
             < forward  name ="success"  path ="/mustlogin.jsp" ></ forward >
         </ action >
         < action  path ="/staticactionforward"  type ="com.ycringfinger.struts.StaticActionForwardTestAction"  scope ="request" >
             < forward  name ="success"  path ="/staticactionforward.jsp" ></ forward >     
         </ action >
         < action  path ="/dynamicactionforward"  type ="com.ycringfinger.struts.DynamicActionForwardTestAction"  scope ="request" >
         </ action >
     </ action-mappings >
    
</ struts-config >

 

2.索引界面index.jsp：

<% ... @ page language="java" import="java.util.*" pageEncoding="GB18030" %>
<! DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" >
< html >
   < head >
   </ head >
  
   < body >
    
     < h1 > 测试ActionForward </ h1 >
    
     < hr >
     < li > 测试ActionForward的redirect属性 </ li >< br >
     < a  href ="mustlogin.do" > 访问受保护的界面 </ a >
    
     < hr >
     < li > 测试静态的ActionForward </ li >< br >
     < a  href ="staticactionforward.do" > 这是一个静态的ActionForward </ a >
    
     < hr >
     < li > 测试动态的ActionForward </ li >< br >
     < form  action ="dynamicactionforward.do" >
        页面: < input  type ="text"  name ="page" >
         < input  type ="submit"  value ="browse" >
     </ form >
    
   </ body >
</ html >

 

3.StaticActionForwardTestAction.java：

package  com.ycringfinger.struts;

import  javax.servlet.http.HttpServletRequest;
import  javax.servlet.http.HttpServletResponse;

import  org.apache.struts.action.Action;
import  org.apache.struts.action.ActionForm;
import  org.apache.struts.action.ActionForward;
import  org.apache.struts.action.ActionMapping;

public   class  StaticActionForwardTestAction  extends  Action  ... {

    public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception ...{
        ActionForward af = mapping.findForward("success");
        //af.setRedirect(true); 不能在这里修改ActionForward的属性,否则将会出错
        return af;
    }

}

 

4.DynamicActionForwardTestAction.java：

 

package  com.ycringfinger.struts;

import  javax.servlet.http.HttpServletRequest;
import  javax.servlet.http.HttpServletResponse;

import  org.apache.struts.action.Action;
import  org.apache.struts.action.ActionForm;
import  org.apache.struts.action.ActionForward;
import  org.apache.struts.action.ActionMapping;

public   class  DynamicActionForwardTestAction  extends  Action  ... {

    public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception ...{
        
        String page = request.getParameter("page");
        ActionForward af = new ActionForward("/" + page + ".jsp", true);
        
        return af;
    }

}
