flex与Java的交互方式及举例

flex4出来一段时间了,去年看了一段时间flex3,后来由于暂时没有项目需求.所以flex遗忘了很多.这次使用flex4+myeclipse8.5录制了一个视频.以免时间长了遗忘.
        软件环境:windows7+flex4+myeclipse8.5+blazeds
        功能描述:分别用代码实现了三种flex4与Java通信
        三种方式:
                       1 flex 与普通java类通信RemoteObject
                       2 flex 与服务器交互HTTPService
                       3 flex与webservice交互WebService
        1 flex 与普通java类通信RemoteObject
       普通Java类:

package com.flex.demo;

/**

* 功能描述:该类用来实现flex与普通java类中的方法通信

* @author Administrator

public class SimpleService {

public String sayHello(String name){

return "Hello, "+name;

}

配置说明:配置remoting-config.xml

<source>com.flex.demo.SimpleService</source>

</properties>

</destination>

调用

<s:RemoteObject id="serv" destination="myservice" fault="serv_faultHandler(event)" result="serv_resultHandler(event)">

</s:RemoteObject>

2flex 与服务器交互HTTPService
servlet代码

package com.flex.demo;

import java.io.IOException;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

/**

* 功能描述:该servlet用来与flex进行交互

* @author Administrator

@SuppressWarnings("serial")

public class SimpleServiceServlet extends HttpServlet {

@Override

protected void service(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

request.setCharacterEncoding("utf-8");

response.setCharacterEncoding("utf-8");

response.getWriter().write("我是服务器");

}

调用

<s:HTTPService id="service" fault="service_faultHandler(event)" result="service_resultHandler(event)" url="http://localhost:8080/flexdemo/simpleServiceServlet">

</s:HTTPService>

3flex与webservice交互WebService

<s:WebService id="ws"

wsdl="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl"

fault="ws_faultHandler(event)"

result="ws_resultHandler(event)"

showBusyCursor="true">

<s:operation name="getWeatherbyCityName">

<s:request>

{city.text}

</theCityName>

</s:request>

</s:operation>

</s:WebService>

三种方式完整的配置例子

<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"

creationComplete="service.send()"

<fx:Script>

<![CDATA[

import mx.controls.Alert;

import mx.rpc.events.FaultEvent;

import mx.rpc.events.ResultEvent;

//错误处理函数

protected function serv_faultHandler(event:FaultEvent):void

{

Alert.show("调用失败了:"+event.fault.message as String,"提示");

}

//成功调用函数

protected function serv_resultHandler(event:ResultEvent):void

{

Alert.show("调用成功了:"+event.result as String,"提示");

}

protected function service_faultHandler(event:FaultEvent):void

{

Alert.show("调用失败了:"+event.fault.message as String,"提示");

}

protected function service_resultHandler(event:ResultEvent):void

{

Alert.show("调用成功了:"+event.result as String,"提示");

}

protected function ws_faultHandler(event:FaultEvent):void

{

Alert.show("调用失败了:"+event.fault.message as String,"提示");

}

//调用成功了

protected function ws_resultHandler(event:ResultEvent):void

{

trace(event.result);

lbl.text=(String)(event.result);

}

//第一种调用webservice的方法

//此方法调用webservice

protected function btn_clickHandler(event:MouseEvent):void

{

//ws.getWeatherbyCityName(city.text);

//第二中调用webservice的方法

ws.getWeatherbyCityName.send();

}

初次接触flex的朋友,看上面的肯定很迷惑,因此这里录制了视频教程,视频的质量是蛮好的,该视频从头至尾演示了flex4整合Java的过程.为了方便在windows平台下播放,该视频默认导出格式为exe,在此说明该文件并非病毒,实乃视频文件,大家可放心观看.点我下载flex4与Java交互演示视频
