flex 绑定properties文件做国际化，以及ant编译

 1.首先要想在flex builder 3里编辑properties文件，先要下载插件，步骤如下：
    Help->Software Updates->Find and Install...->Search for new features to install 点击next.
点击"New Remote Site...",输入name:Arbitrary input, URL: http://propedit.sourceforge.jp/eclipse/updates/

一路回车安装之后会自动重启。ok，你现在就可以编辑properties文件了。

2.建议将国际化文件properties文件放到一个统一的目录，我这里放到property文件夹里，同时将此文件夹加入到flex build path的source path中



 



zh.properties代码如下

 

#注释

#

flex_label1=欢迎大家

flex_label2=各位好啊

flex_message={0}赶在{1}之前到的.

 3.编写一个工具类来读取properties文件如下：

public class ResourceUtil extends EventDispatcher{

     private static var _instance : ResourceUtil;

     private var _language : String;

    [ResourceBundle("en")]    

    private var lang_en:ResourceBundle;    

          

    [ResourceBundle("zh")]    

    private var lang_zh:ResourceBundle;       

//    [Bindable] 

//    private var localResources:ResourceBundle;

          

     public static function getInstance() : ResourceUtil {    

      if (_instance == null) {    

                _instance = new ResourceUtil();    

   }

         return _instance;    

  }

     [Bindable(event="languageChange")]    

     public function getString(key:String):String {    

             return ResourceManager.getInstance().getString(_language,key);//localResources.getString(key);    

    }

    /**

      * get the substitute properties by key and other parameter

      */

     [Bindable(event="languageChange")]    

   public function ResourceUtil(){

          this.language = "zh";

   }

   public function set language(language : String):void {    

            this._language = language;    

           /*     

            if (_language == "en") {    

                this.localResources = lang_en;    

            } else if (_language == "zh") {    

                this.localResources = lang_zh;    

            } else {    

                this.localResources = lang_en;    

            } */    

            dispatchEvent(new Event("languageChange"));    

    } 

   }

4.在应用中就可以使用了

     public function getSubstitute(key : String, ... rest):String
    {
         return StringUtil.substitute(ResourceManager.getInstance().getString(_language,key),rest);
    }

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

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" >   

   

    <mx:Script>   

        <![CDATA[

            import mx.resources.ResourceManager;    

            import com.ResourceUtil; 

               

            [Bindable]   

            private var ru : ResourceUtil = ResourceUtil.getInstance();                         

            

            private function changeLanguage(language:String):void {   

                ru.language = language;   

            }   

        ]]>

    </mx:Script>   

    <mx:Label id="label1" x="10" y="10" text="{ru.getString('flex_label1')}" />   

    <mx:Label id="label2" x="10" y="38" text="{ru.getString('flex_label2')}"/>   

    <mx:Label id="label3" x="10" y="58" text="{ru.getSubstitute('flex_message','Anant', 'Nick')}" />   

    <mx:Button x="10" y="88" label="Chinese" click="changeLanguage('zh')"/>   

    <mx:Button x="88" y="88" label="English" click="changeLanguage('en')"/>   

</mx:Application> 
 5.还要注意ant build 的时候

<target name="buildMain" depends="init">

        <mxmlc file="${src.dir}/ResourceTest.mxml" output="${dest.dir}/ResourceTest.swf">

            <load-config filename="${FLEX_CONFIG_FILE}"/>

            <source-path path-element="${basedir}/property" />

        </mxmlc>

    </target>
