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。
/*==============================================================*/
/**//* Table: tblmobile */
/**//*==============================================================*/
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)
);
/**//*==============================================================*/
/**//* Index: i_tblMobile_categoryid */
/**//*==============================================================*/
create index i_tblMobile_categoryid on tblmobile
(
categoryid
);
/**//*==============================================================*/
/**//* Index: pk_tblmobile */
/**//*==============================================================*/
create unique index pk_tblmobile on tblmobile
(
id
);
/**//*==============================================================*/
/**//* Index: i_tblmobile_addtime */
/**//*==============================================================*/
create index i_tblmobile_addtime on tblmobile
(
addtime
);
phonselist.jspJsp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 {
Class .Class.forName("com.mysql.jdbc.Driver").newInstance();
url = "jdbc:mysql://localhost/web?user=flex&password=flex&useUnicode=true&characterEncoding=gb2312";
Connection conn = DriverManager.getConnection(url);
Statement stmt = conn.createStatement();
sql = "select id, name, price, image from tblMobile where categoryid=" + categoryID;
ResultSet rs = stmt.executeQuery(sql);
while (rs.next()){
out.println("<phone id=\"" + rs.getString(1) + "\">");
out.println("<id>" + rs.getString(1) + "</id>");
out.println("<name>" + rs.getString(2) + "</name>");
out.println("<price>" + rs.getString(3) + "</price>");
out.println("<image>" + rs.getString(4) + "</image>");
out.println("</phone>");
}
rs.close();
stmt.close();
conn.close();
} catch (Exception e) {
out.println(e);
}
%>
</phonelist>
mobile.mxml这里要注意一下
<mx:HTTPService>中的
resultFormat="xml"的设置，在这里应该把这个取掉（我原来是用来做Tree用的）。phonelisg.jsp和mobile.mxml放在相同的目录下，当然你也可以修改
url的路径。
