?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

id
="myservice"

="serv"
?destination
="myservice"
?fault
="serv_faultHandler(event)"
?result
="serv_resultHandler(event)"

????????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;

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");
 ????}
 }

?flex?与服务器交互
s:HTTPService?
="service"
="service_faultHandler(event)"
="service_resultHandler(event)"
?url
="http://localhost:8080/flexdemo/simpleServiceServlet"
s:HTTPService
????????3flex与webservice交互WebService
flex与webservice交互这里调用一个天气预报的webservice
s:WebService?
="ws"
?
 ??????????????????????wsdl
="http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl"
?
 ??????????????????????fault
="ws_faultHandler(event)"
?
 ??????????????????????result
="ws_resultHandler(event)"
?
 ??????????????????????showBusyCursor
="true"
?第二种调用webservice的方法<s:operation>
-->
 ????????????
?<s:operation?name="getWeatherbyCityName">?webservice中的方法名
s:operation?
name
="getWeatherbyCityName"
>
 ????????????????
传递的参数
-->
 ????????????????
s:request
>
 ????????????????????
参数名称必须与webservice中定义的参数名一致否则调用不成功报错
-->
 ????????????????????
theCityName
>
 ????????????????????????{city.text}
 ????????????????????

????????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.
