我目前正在尝试通过 LCDS 映射带有 Flex ArrayCollection 的 java ArrayList。我的 Flex 应用程序确实调用了返回 ArrayList 的 Java 方法，但我还没有设法检索 ArrayList 以在 Flex 端的 DataGrid 中显示它。
JavaSide：我有 2 个类： - Jco_test.java：它包含方法 public ArrayList all() - Customclass.java：它包含一个初始化一些变量的构造函数
public class CustomClass {
String airline;
String cityFrom;
String cityTo;
Date flightDate;
BigDecimal price;
public CustomClass(String s1, String s2, String s3, Date d, BigDecimal bd){
airline = s1;
cityFrom = s2;
cityTo = s3;
flightDate = d;
price = bd;
}
}
弹性边：
测试.mxml：
import mx.messaging.AbstractConsumer; import mx.collections.ArrayCollection; import mx.rpc.events.FaultEvent; import mx.rpc.events.ResultEvent; import mx.controls.Alert; public var flightList:ArrayCollection; public function ResultHandler(event:ResultEvent):void{ flightList = (event.result as ArrayCollection); } public function FaultHandler(event:FaultEvent):void{ flightList = new ArrayCollection(); ta.text = "Error id: " + event.fault.errorID + "\n"; ta.text += "String: " + event.fault.faultString + "\n"; ta.text += "Code: " + event.fault.faultCode + "\n"; ta.text += "Detail: " + event.fault.faultDetail + "\n"; ta.text += "Stack: \n" + event.fault.getStackTrace() + "\n"; }
RemoteObject id="ro" 目的地="jco" 结果="ResultHandler(event);" 故障=“故障处理程序（事件）；”
<mx:Panel title="monTest" width="699" height="549" x="10">
<mx:Button label="go" click="ro.all();"/>
<mx:DataGrid dataProvider="flightList">
<mx:columns>
<mx:DataGridColumn dataField="AIRLINE" headerText="Airline" />
<mx:DataGridColumn dataField="CITYFROM" headerText="From" />
<mx:DataGridColumn dataField="CITYTO" headerText="To" />
<mx:DataGridColumn dataField="FLIGHTDATE" headerText="Date" />
<mx:DataGridColumn dataField="PRICE" headerText="Price" />
</mx:columns>
</mx:DataGrid>
<mx:TextArea id="ta" width="100%" height="219"/>
</mx:Panel>
CustomClass.as：
[Bindable] [RemoteClass(alias="utils.CustomClass")] public class CustomClass{ public var airline:String; public var cityFrom:String; public var cityTo:String; public var flightDate:Date; public var price:String; }
难道我做错了什么？我仍然有一些疑问......我的 ArrayList 没有标题。如何检索 DataGridColumn 中的数据？
感谢您的任何帮助，您可以提供。问候。
（对不起格式问题...）
我确实忘记了 getter 和 setter。现在，我可以在服务器日志中看到我正在寻找的值。但 Flex 仍然无法显示数据。
这是日志：

我不确定 DataGridColumn 的数据字段是否区分大小写，所以我更改了数据字段以匹配每个字段。
