flex 整合 struts 的一个简单示例(使用Httpservice)

关于在Eclipse下 flex整合java的配置请参考： http://aaacd.blog.hexun.com/15758049_d.html

这里是一个flex整合struts的一个基本的例子

1. testFlex10.mxml

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute"
backgroundColor="#FFFFFF"
backgroundAlpha="0" horizontalCenter="true" >
<mx:HTTPService id="info" url="test.do">
<mx:request>
<username>
{userId.text}
</username>
<userpwd>
{password.text}
</userpwd>
</mx:request>
</mx:HTTPService>
<mx:TitleWindow id ="loginWindow" xmlns:mx="http://www.adobe.com/2006/mxml" title="Logon" x="350" y="80">
<mx:Form>
<mx:FormItem label="LUserId" required="true">
<mx:TextInput id="userId" width="150">
</mx:TextInput>
</mx:FormItem>
<mx:FormItem label="LPassword" required="true">
<mx:TextInput id="password" width="150"/>
</mx:FormItem>
<mx:FormItem>
<mx:HBox horizontalGap="30">
<mx:Button label="Logon" click="info.send();" />
<mx:Button label="Cancel" click="info.send();"/>
</mx:HBox>
</mx:FormItem>
</mx:Form>
</mx:TitleWindow>
<mx:DataGrid dataProvider="{info.lastResult.userinfo.user}" width="60%" x="160" y="300" >
<mx:columns>
<mx:Array>
<mx:DataGridColumn headerText="姓名" dataField="username"/>
<mx:DataGridColumn headerText="密码" dataField="userpwd"/>
<mx:DataGridColumn headerText="邮件" dataField="useremail"/>
<mx:DataGridColumn headerText="年龄" dataField="userage"/>
</mx:Array>
</mx:columns>
</mx:DataGrid>
</mx:Application>

核心代码：

<mx:HTTPService id="info" url="test.do">
<mx:request>
<username>
{userId.text}
</username>
<userpwd>
{password.text}
</userpwd>
</mx:request>
</mx:HTTPService>

以及

dataProvider="{info.lastResult.userinfo.user}"

2.struts.config.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN" "http://struts.apache.org/dtds/struts-config_1_2.dtd">

<struts-config>
<data-sources />
<form-beans >
<form-bean name="testForm" type="com.yourcompany.struts.form.TestForm" />

</form-beans>

<global-exceptions />
<global-forwards />
<action-mappings >
<action
attribute="testForm"
input="/form/test.jsp"
name="testForm"
path="/test"
scope="request"
type="com.yourcompany.struts.action.TestAction" >
<forward name="success" path="/MyJsp.jsp"></forward>
</action>
</action-mappings>

<message-resources parameter="com.yourcompany.struts.ApplicationResources" />
</struts-config>

3.Action: TestAction.java

package com.yourcompany.struts.action;

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;
import com.yourcompany.struts.form.TestForm;

public class TestAction extends Action {

public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
TestForm testForm = (TestForm) form;// TODO Auto-generated method stub
String name = testForm.getUsername();
System.out.println("fadf : " + name);
return (mapping.findForward("success"));
}
}

4. MyJsp.jsp

<%@page import="
java.util.List"%>
<%
response.setContentType("text/xml");
out.println("<?xml version=/"1.0/" encoding=/"utf-8/"?>");
out.println("<userinfo>");

out.println("<user userId=/""+3123+"/">");
out.println("<username>"+42314+"</username>");
out.println("<userpwd>"+3123+"</userpwd>");
out.println("<useremail>"+4231+"</useremail>");
out.println("<userage>"+2+"</userage>");
out.println("<regdate>"+4231+"</regdate>");
out.println("</user>");

out.println("</userinfo>");
%>
