6，以下是flex端，UserFlex.as

? package com.flex??
{??
??? [Bindable]??
???
[RemoteClass(alias="com.datainfo.User")]??
??? public class UserFlex??

??? {??
//????? public function UserFlex{??
//????????????

//????? }??
??????? public var id:int;??
??????? public var
username:String;??
??????? public var password:String;??

//????? 如果用private，就需要写上get/set??

//????????
//????? public function get id():int{??

//????????? return this.id;??
//????? }??
//????? public function
set id():int{??
//????????? this.id = id;??
//????? }??
//????????

//????? public function get username():String{??
//????????? return
this.username;??
//????? }??
//????? public function set
username():String{??
//????????? this.username = username;??
//????? }??

//????????
//????? public function get password():String{??

//????????? return this.password;??
//????? }??
//????? public
function set password():String{??
//????????? this.password = password;??

//????? }??
??? }??
}?
