对于建立一个flex web应用的步骤我就不多说了哈。
首先要求大家到数据库建立一个数据库，在我这例子中数据库名为userDb，建立一个表userInfo，里面设置两个字段一个为id，一个为name.第二，创建以下java代码在src目录下
User.java
package
org.rjb.java;
public
class
User
{
private
Stringname;
public
StringgetName()
{
return
name;
}
public
void
setName(Stringname)
{
this
.name
=
name;
}
}
UserDao.java
package
org.rjb.java;
import
java.sql.Connection;
import
java.sql.DriverManager;
import
java.sql.ResultSet;
import
java.sql.SQLException;
import
java.sql.Statement;
import
java.util.ArrayList;
import
java.util.List;
public
class
UserDao
{
public
static
ConnectiongetConnection()
{
Connectionc
=
null
;
try
{
Stringdriver
=
"
com.mysql.jdbc.Driver
"
;
Stringurl
=
"
jdbc:mysql://localhost:3306/userDb
"
;
Stringusername
=
"
root
"
;
Stringpassword
=
"
1235
"
;
Class.forName(driver);
c
=
DriverManager.getConnection(url,username,password);
}
catch
(Exceptione)
{
System.out.println(e.getMessage());
}
return
c;
}
public
ListgetAllUser()
throws
SQLException
{
Connectionc
=
getConnection();
Statementst
=
c.createStatement();
ResultSetrs
=
st.executeQuery(
"
select*fromUserInfo
"
);
ArrayListuserList
=
new
ArrayList
<
User
>
();
while
(rs.next())
{
Useru
=
new
User();
u.setName(rs.getString(
"
name
"
));
userList.add(u);
}
return
userList;
}
}
|
以上是java端的全部代码了，下面是flex端的代码。
第三，创建以下代码在flex_src下：
|
User.as
package
org.rjb.flex
{
[RemoteClass(alias
=
"
org.rjb.java.User
"
)]
public
class
User
{
private
var_name:String;
public
functionUser()
{
}
public
functiongetname():String
{
return
this
._name;
}
public
functionsetname(name:String):
void
{
this
._name
=
name;
}
}
}
User.as
package
org.rjb.flex
{
[RemoteClass(alias
=
"
org.rjb.java.User
"
)]
public
class
User
{
private
var_name:String;
public
functionUser()
{
}
public
functiongetname():String
{
return
this
._name;
}
public
functionsetname(name:String):
void
{
this
._name
=
name;
}
}
}
|
接下来是mxml代码，也就是我们真正展示我们数据的界面
|
FlexWith
Java
.mxml
<?
xmlversion="1.0"encoding="utf-8"
?>
<
mx:Application
xmlns:mx
="http://www.adobe.com/2006/mxml"
layout
="vertical"
>
<
mx:RemoteObject
id
="ud"
destination
="UserDao"
result
="onResult(event)"
fault
="onFault()"
/>
<
mx:DataGrid
dataProvider
="{users}"
>
<
mx:columns
>
<
mx:DataGridColumn
dataField
="name"
headerText
="name"
/>
</
mx:columns
>
</
mx:DataGrid
>
<
mx:Label
id
="info"
/>
<
mx:Button
label
="click"
click
="clickFun()"
/>
<
mx:Script
>
<![CDATA[
importmx.collections.ArrayCollection;
importmx.rpc.events.ResultEvent;
[Bindable]
publicvarusers:ArrayCollection=newArrayCollection();
publicfunctionclickFun():void{
ud.getAllUser();
}
publicfunctiononResult(event:ResultEvent):void{
users=ArrayCollection(event.result);
info.text="getdatasuccessfully";
}
publicfunctiononFault():void{
info.text="Error";
}
]]>
</
mx:Script
>
</
mx:Application
>
|
第四，配置remoting-config.xml，在里面加上如下配置文件：
<
destination
id
="UserDao"
>
<
properties
>
<
source
>
org.rjb.java.UserDao
</
source
>
</
properties
>
</
destination
>
