如何调用使用BlazeDS的只有“long”类型参数的方法？

Question

我不能调用使用Adobe BlazeDS的只有“long”类型参数的方法吗？

这是它。

[Flex的]

var ro:RemoteObject = new RemoteObject(); 
ro.destination = "objectService"; 
ro["getById"].send(3107); 

【JAVA]

public class ObjectServiceImpl implements ObjectService { 
    public ObjectDomain getById(long id) { 
     ・・・ 
    } 
} 

所以，这个错误是发生。

flex.messaging.MessageException: Cannot invoke method 'getById'. 3,107 
arguments were sent but 1 were expected.

[环境] ·BlazeDS的4.0 ·春天BlazeDS集成1.0.3 ·春3.0.5 ·Tomcat的5.0 ·Java 5.0中 ·Flex的4.6

请告诉我任何解决方案。 。

Answer 1

尝试以下操作：

 //The way you defined the RemoteObject 
     var ro:RemoteObject = new RemoteObject(); 
     ro.destination = "objectService"; 

     //The id variable 
     var id:Number = 3107; 
     //The Operation to send over the RemoteBoject 
     var getByIdOperation:Operation = new Operation(); 
     //Name of the method on the server side 
     getByIdOperation.name = "getById"; 
     //The argument in this case the long 3107 (var id:Number= 3107) 
     getByIdOperation.arguments = [id]; 
     //The method to handle the result if needed 
     getByIdOperation.addEventListener(ResultEvent.RESULT, getByIdHandler) 
     //Send the operation through the RemoteObject(ro) 
     ro.operations = [getByIdOperation]; 
     getByIdOperation.send();  

java.lang。 Long在ActionScript-3中表示为Number。当远程电话收到结果时调用的示例方法

private function getByIdHandler(event:ResultEvent):void 
    { 
     myObject = event.result as ObjectDomain; 
    }
