flex4与Java交互

  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

< destination id ="myservice" >

< properties >

< 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 >

< theCityName >

{city.text}

</ theCityName >

</ s:request >

</ s:operation >

</ s:WebService >

三种方式完整的配置例子

<? 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"

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
