我有一个 flex Web 应用程序，它请求一个 servlet，而 servlet 发回一个数组列表。我在结果事件中以字符串形式获取数据。我想在 flex 端获取 arraycollection。我该怎么做。同时让我知道，可以像我那样做吗？下面是代码
弯曲端：
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
<fx:Script>
<![CDATA[
import mx.controls.Alert;
import mx.rpc.events.ResultEvent;
import mx.rpc.http.HTTPService;
import mx.utils.ObjectUtil;
protected function callBackEnd(event:MouseEvent):void
{
var params:Object = {name: 'debarshi',password:'banerjee'};
rawFileServlet.send(params);
rawFileServlet.addEventListener(ResultEvent.RESULT,onResult);
}
private function onResult(ev:ResultEvent):void
{
Alert.show(ObjectUtil.toString(ev.result));
}
]]>
</fx:Script>
<fx:Declarations>
<s:HTTPService url="http://192.168.1.66:8484/HelloWorldServlet/TestServlet"
id="rawFileServlet"
method="POST"
showBusyCursor="true"/>
</fx:Declarations>
<s:Button click="callBackEnd(event)" label="Click"/>
</s:Application>
flex 端的对象类：
package
{
[Bindable]
[RemoteClass(alias="com.rit.test.java.model.Employee")]
public class Employee
{
private var id:int;
private var name:String;
private var address:String;
private var salary:int;
public function setId(_id:int):void
{
this.id = _id;
}
public function getId():int
{
return this.id;
}
public function setName(_name:String):void
{
this.name = _name;
}
public function getName():String
{
return this.name;
}
public function setAddress(_address:String):void
{
this.address = _address;
}
public function getAddress():String
{
return this.address;
}
public function setSalary(_sal:int):void
{
this.salary = _sal;
}
public function getSalary():int
{
return this.salary;
}
public function Employee()
{
}
}
}
java servlet 类：
package com.rit.test.java;

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out = response.getWriter();
populateList();

out.println(ast.convert(list, ArrayCollection.class));
out.flush();
}
private void populateList(){
Employee emp = new Employee();

emp.setId(5);
emp.setName("Sanket");
emp.setAddress("keshtopur");
emp.setSalary(40);
list.add(emp);
}
}
object class in java end:

public void setId(int _id)
{

我在 flex 端收到的警报是：“[com.rit.test.java.model.Employee@1ae209, com.rit.test.java.model.Employee@edd06a, com.rit.test.java.model.Employee @10df737，com.rit.test.java.model.Employee@1e17d0b，com.rit.test.java.model.Employee@d89588]
"
我在我的 java lib 文件夹中添加了五个 blaze DS .jar 文件（flex-messaging-common、flex-messaging-core、flex-messaging-opt、flex-messaging-proxy、flex-messaging-remoting）。使用这五个 .jar 文件我在 java 端翻译成 flex arraycollection 并发送。这是我可以接近的正确方法吗？请帮忙
