贴个Flex-Jsp-Mysql简单结合例子

数据库表
这个sql是用pd生成的，具体内容大家自己看一下好了，很简单，数据也自己填充一下。标题上说是用mysql，其实无所谓用啥数据库了，这里我推荐Postgresql，现在有for win平台了，不用cygwin来模拟unix环境，这个Postgresql一来小巧，二来功能齐全，看起来有点象Oracle，当然速度也很快了。

create table tblmobile
(
id integer(11) not null default 0,
categoryid integer(11),
name varchar(255),
image varchar(255),
price decimal(12,2),
addtime datetime,
primary key (id)
);

create index i_tblMobile_categoryid on tblmobile
(
categoryid
);

create unique index pk_tblmobile on tblmobile
(
id
);

create index i_tblmobile_addtime on tblmobile
(
addtime
);


phonselist.jsp
Jsp服务器用的是Tomcat，顺便做flex的服务器，版本没啥大关系，我现在用的是5.0.28，Jsp功能是按手机分类id从mysql数据库获取手机列表，这里为方便起见直接在jsp页面里进行数据库访问，正确的做法应该由javabean来分工，其后总jsp生成的是一个xml文件。

<?xml version="1.0" encoding="utf-8"?>
<%@ page contentType="text/html;charset=utf-8"%>
<%@ page import="java.sql.*"%>
<phonelist>
<%
String sql = "";
String url = "";

String categoryID = request.getParameter("categoryID");

try {
<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="http://www.macromedia.com/2003/mxml"
verticalGap="10"
backgroundColor="#FFFFFF"
pageTitle="手机"
initialize="initApp()">

<mx:Style source="main.css"/>

<mx:HTTPService id="phoneService" url="phonelist.jsp" resultFormat="xml">
<mx:request>
<categoryID>{categoryId}</categoryID>
</mx:request>
</mx:HTTPService>

<mx:Model id="phonelist">
{phoneService.result.phonelist.phone}
</mx:Model>

<mx:Script>
<![CDATA[

var categoryId = 2;
var categoryName = "Moto";

function initApp() {
phoneService.send();
}

]]>
</mx:Script>

<mx:HBox>
<mx:LinkBar styleName="title" width="500" click="" >
<mx:dataProvider>
<mx:Array>

<mx:Button label="下一页" click=""/>
<mx:Button label="refresh" click="initApp()"/>

</mx:Panel>
</mx:HBox>

<mx:HBox horizontalAlign="center">
<mx:Label text="Copy Right 2004 dannyr's Studio "/>
</mx:HBox>
</mx:Application>

最后：配置Flex服务器
flex-config.xml
