用flex连接jsp应用

创建sendData.as文件

java 代码

// ActionScript file
package com.firebow.flex {

import flash.events.Event;
import flash.events.HTTPStatusEvent;
import flash.events.IOErrorEvent;
import flash.events.ProgressEvent;
import flash.events.SecurityErrorEvent;
import flash.net.URLLoader;
import flash.net.URLLoaderDataFormat;
import flash.net.URLRequest;
import flash.net.URLRequestMethod;
import flash.net.URLVariables;

import mx.controls.DataGrid;
import mx.controls.List;

import mx.controls.Label;
import mx.controls.CheckBox;



//

// 配置 URLVariables, 设置传递到

//


public class SendData
{
    var loader:URLLoader = new URLLoader();
    var list:Array=new Array();
    var isFinish:Boolean=new Boolean(false);
    var dataGrid:DataGrid;
    public function getUsers(userName:String,dg:DataGrid):void{
        var variables:URLVariables = new URLVariables();

        variables.userName = userName;

        //

        // 配置 URLRequest, 设置目标路径, 设置提交的数据, 方法 (POST / GET)

        //
        var request:URLRequest = new URLRequest("http://127.0.0.1/admin/ajaxQueryUserList.do");

        request.data = variables;

        request.method = URLRequestMethod.POST;

        //

        // 配置 URLLoader, 注册侦听器等

        //

        //

        // 服务端将要返回的是纯文本数据

        //
        loader.dataFormat = URLLoaderDataFormat.TEXT;

        loader.addEventListener(Event.COMPLETE, loader_complete);

        loader.addEventListener(Event.OPEN, loader_open);

        loader.addEventListener(HTTPStatusEvent.HTTP_STATUS, loader_httpStatus);

        loader.addEventListener(ProgressEvent.PROGRESS, loader_progress);

        loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, loader_security);

        loader.addEventListener(IOErrorEvent.IO_ERROR, loader_ioError);

        loader.load(request);


        dataGrid=dg;
    }


    function loader_complete (e:Event):void {

         trace("Event.COMPLETE");

         trace("目标文件的原始数据 (纯文本) : \n" + loader.data);
         var result:XML=new XML(loader.data);

         var datas:Array=[];
         for each ( var element:XML in result.elements(  ) ) {

            trace(element.child("userName"));
            var rec:Object = {col1:false,col2:element.child("userName"), col3:element.child("cnName")};
            datas.push(rec);

        }
        dataGrid.dataProvider=datas;

    }

    function loader_open (e:Event):void {

         trace("Event.OPEN");

         trace("读取了的字节 : " + loader.bytesLoaded);

    }

    function loader_httpStatus (e:HTTPStatusEvent):void {

         trace("HTTPStatusEvent.HTTP_STATUS");

         trace("HTTP 状态代码 : " + e.status);

    }

    function loader_progress (e:ProgressEvent):void {

         trace("ProgressEvent.PROGRESS");

         trace("读取了的字节 : " + loader.bytesLoaded);

         trace("文件总字节 : " + loader.bytesTotal);

    }

    function loader_security (e:SecurityErrorEvent):void {

        trace("SecurityErrorEvent.SECURITY_ERROR");

    }

    function loader_ioError (e:IOErrorEvent):void {

        trace("IOErrorEvent.IO_ERROR");

    }
}
}

创建text.mxml文件

xml 代码

xml version="1.0" encoding="GBK"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" initialize="loadStyles()" layout="absolute" updateComplete="showApp()" >

    <mx:Button x="169" y="10" label="你好" fontFamily="Arial" fontWeight="bold"  click="doClick()"/>

    <mx:Script>
        <!---->
    <!---->mx:Script>
    <mx:TextInput x="10" y="10" id="inputTxt"/>
    <mx:DataGrid y="33" x="10" id="tb">
        <mx:columns>
            <mx:DataGridColumn headerText="选择" textAlign="center" dataField="col1"  itemRenderer="mx.controls.CheckBox" />
            <mx:DataGridColumn headerText="帐号" textAlign="center" sortable="true" dataField="col2" itemRenderer="mx.controls.Label" />
            <mx:DataGridColumn headerText="姓名" textAlign="center" dataField="col3" itemRenderer="mx.controls.Label" />
        <!---->mx:columns>

    <!---->mx:DataGrid>
<!---->mx:Application>

建立样式表文件mycss.css

js 代码

/* CSS file */
Button{

   fontSize:12px;
   fontFamily:"宋体";
}
Label{
   color:red;
   fontSize:12px;
   fontFamily:"宋体";
}

运行 mxmlc style.css
jsp中返回xml数据
