? ? ? ? 总结一下Flex与Servlet之间数据的交互：
? ? ? ??代码1—Flex代码：

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="sendRequest();">
	<mx:Script>
		<![CDATA[
		  	import mx.controls.Alert;
		           
		  	public function sendRequest():void{
			  	var request:URLRequest=new URLRequest("http://localhost:8080/flexAndServlet/TestServlet");//首先发送servlet请求：flexAndServlet为Java Web工程名、TestServlet为处理Flex发送过来的数据的Servlet
			    request.method=URLRequestMethod.POST;
			    request.data = new URLVariables("name=高焕杰"); //name为传向Servlet的参数名
			    var loader:URLLoader=new URLLoader();
			    loader.load(request);
			    loader.addEventListener(Event.COMPLETE,onLoaderComplete);
		  	}
		
		  	private function onLoaderComplete(event:Event):void{
		    	var responseResult:String = ((event.target) as URLLoader).data;//servlet端传回来的数据
		    	Alert.show(responseResult,"");
		  	}
		]]>
	</mx:Script>
</mx:Application>

? ? ? ??代码2—Servlet代码：

package com.ghj.packageofservlet;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class TestServlet extends HttpServlet {

	private static final long serialVersionUID = -2928176190622974743L;

	public void doGet(HttpServletRequest request,HttpServletResponse response)throws ServletException,IOException {
		doPost(request,response);
	}

	public void doPost(HttpServletRequest request,IOException {
		request.setCharacterEncoding("UTF-8");
		response.setContentType("text/pain;charset=UTF-8");
		PrintWriter out = response.getWriter();
		try {
			String name = request.getParameter("name");//获取Flex发送回来的名为name的参数对应的参数值
			System.out.print("name：" + name);
			out.println("Servlet获取的值为" + name);
		} finally {
			out.close();
		}
	}
}

? ? ? ??代码3—web.xml代码：

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