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>

</global-forwards>

<action-mappings>

</action>

</action>

</action>

</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>

页面:<input type="text" name="page">

</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;

}
