Flex+J2EE实例（cairngorm+blazeDS+hibernate+spring） part2

1.编写后台Java 处理方法：

在src文件下建一个包com

在com下建class文件，命名为Hello

添加处理代码：

package com;

?

public class Hello {

??? ?public String hello(String name){

??? ? System.out.println("flex 调用Java！name="+name);

??? ? return "hello "+name;

??? ?}

}

?

2.配置remoting-config.xml

添加代码

??? ?<destination id="hello">

??? ??????? <properties>

??? ??????????? <source>

??? ??????????????? com.Hello

??? ??????????? </source>

??? ??????? </properties>

??? ?</destination>

如下

3. 修改flex_src?? 下 FlexJ2ee.mxml文件

?

<?xml version="1.0" encoding="utf-8"?>

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"

              xmlns:s="library://ns.adobe.com/flex/spark"

              xmlns:mx="library://ns.adobe.com/flex/mx" 

minWidth="955" minHeight="600">

    <fx:Declarations>

       <!-- 将非可视元素（例如服务、值对象）放在此处 -->

       <s:RemoteObject destination="hello" id="hell_RO" result="gg(event)"                   endpoint="http://localhost:8089/FlexJ2ee/messagebroker/amf">

       </s:RemoteObject>

    </fx:Declarations>

    <fx:Script>

       <![CDATA[

           import mx.rpc.events.ResultEvent;

           import mx.controls.Alert;

           

           private function gg(e:ResultEvent):void{

              var backText:String = e.result as String;

              backTxt.text = backText;

           }

           

           protected function RemotingSayHello(event:MouseEvent):void

           {

              var sname:String = nameInput.text;

              hell_RO.hello(sname);

           }

       ]]>

    </fx:Script>

    

    <s:TextArea id="backTxt" x="109" y="122" height="99"/>

    <s:Button label="send" click="RemotingSayHello(event)" x="110" y="243"/>

    <s:TextInput id="nameInput" x="109" y="73"/>

    <s:Label x="47" y="75" text="Rieciver:"/>

    <s:Label x="47" y="36" text="这是我的第一个FLEXJ2EE项目    

            欢迎大家访问我的BLOG

            http://blog.csdn.net/kkkloveyou"/>

</s:Application>

4. 打开http://localhost:8089/FlexJ2ee/flex/FlexJ2ee.html

在Rieciver输入框中填入 May

点击“send”

返回如下“hello May”，说明flex 与java 通信成功

5．控制台输出如下
