编写service类：

package services {    import com.adobe.serialization.json.JSON;        import log.LogUtil;        import mx.collections.ArrayCollection;    import mx.collections.XMLListCollection;    import mx.controls.Alert;    import mx.rpc.events.ResultEvent;    import mx.rpc.http.mxml.HTTPService;            public class CategoryService extends HTTPService {        [Bindable]        public var categoryArray:ArrayCollection;        public var testFlag:Boolean = true;                public function CategoryService(rootURL:String=null, destination:String=null) {            super(rootURL, destination);            this.url = "http://192.168.1.210:8081/xxx.action";//url为远程请求接口            addEventListener(ResultEvent.RESULT, handleCategoryResult);                    }                private function handleCategoryResult(event:ResultEvent):void{            var rawData:String =  String(event.result);            trace(rawData);            LogUtil.debug("CategoryService",rawData);            var o:Object = com.adobe.serialization.json.JSON.decode(rawData);//对结果进行json转换              categoryArray = new ArrayCollection(o.result);        }                                        }}

结果集接收之后进行json格式转换，需要导入as3corelib.swc

在XML中引入：

　　

在方法中调用：
