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"

?destination

?fault
="serv_faultHandler(event)"
?result

</

????????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(
"

)
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

?fault
="service_faultHandler(event)"
?result
="service_resultHandler(event)"
?url

????????3flex与webservice交互WebService
<!--

??????????????????????result

?
??????????????????????showBusyCursor
="true"

????????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.
