Flex 对Java端返回Collection的处理

Flex 对Java端返回Collection的处理方法 将Flex与Spring集成后（BlazeDS 与Spring集成指南 ），
第一个面临的问题就是：对于Java端返回的各种Java类型的对象，Flex中能否有相应的数据类型来映射处理，尤其是List、Set、Map及POJO对象值。
在 BlazeDS 与Spring集成指南 例子的基础上，调整相关的测试代码如下：

一、java端
1）JavaSendList.java

import java.util.ArrayList;
import java.util.HashMap;
import java.util.HashSet;
import java.util.List;
import java.util.Map;
import java.util.Set;

public class JavaSendList {

	public String hello(String var1) {
		return "hello " + var1;
	}

	public String world(String var1) {

		return "world " + var1;
	}

	public Map<String, List> getMap() {
		ArrayList list1 = new ArrayList();
		list1.add("value11");
		list1.add("value12");
		list1.add("value13");

		ArrayList list2 = new ArrayList();
		list2.add("value21");
		list2.add("value22");
		list2.add("value23");
		ArrayList list3 = new ArrayList();
		list3.add("value31");
		list3.add

		("value32");
		list3.add("value33");
		HashMap<String, List> map = new HashMap<String, List>();
		map.put("key1", list1);
		map.put("key2", list2);
		map.put("key3", list3);
		return

		map;
	}

	public ArrayList getList() {
		ArrayList list = new ArrayList();
		Person p1 = new Person();
		p1.setName("name1");
		p1.setPass("pass1");
		Person p2 = new Person();

		p2.setName("name2");
		p2.setPass("pass2");
		Person p3 = new Person();
		p3.setName("name3");
		p3.setPass("pass3");
		list.add(p1);
		list.add(p2);
		list.add(p3);
		return list;
	}

	public Set getSet() {
		HashSet set = new HashSet();
		Person p1 = new Person();
		p1.setName("name1");
		p1.setPass("pass1");
		Person p2 = new Person();
		p2.setName("name2");

		p2.setPass("pass2");
		Person p3 = new Person();
		p3.setName("name3");
		p3.setPass("pass3");
		set.add(p1);
		set.add(p2);
		set.add(p3);
		return set;
	}
}

2)Person.java

public class Person {

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getPass() {
		return pass;
	}

	public void setPass(String pass) {
		this.pass = pass;
	}

	private String name;
	private String pass;
}

二、flex端
1）flexAcceptList.mxml

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

		<s:BasicLayout/>
	</s:layout>
	<fx:Declarations>
		<!-- 将非可视元素（例如服务、值对象）放在此处 -->
	</fx:Declarations>
	
	<fx:Script>
		<![CDATA[

			function sayHello(event:Event):void { 
//				var inputVar:String=inputStr.text;

			private function getMapResult(event:ResultEvent):void {

					var list:ArrayCollection=event.result[key] as ArrayCollection; 
					for (var key1:Object in list) { 
						Alert.show("map item key is: " + key + " value is: " + key1); 
					} 
				} 
			} 
			
			private function getList():void { 
//				test1.getList(); 
			} 
			
			private function getListResult(event:ResultEvent):void { 
				var ac:ArrayCollection=event.result as ArrayCollection; 
				for (var i:int=0; i < ac.length; i++) { 
					var p1:Person=ac.getItemAt(i) as Person; 
					Alert.show("list item name is: " + p1.name+" \n another usage : "+ac.getItemAt(i).name);

					Alert.show("set item name is: " + p1.name); 
				} 
			} 
		]]>

</s:Application>

2)Person.as

package
{
	[Bindable] 
	[RemoteClass(alias="com.yeeach.Person")] 
	public class Person
	{
		public var name:String; 
		public var pass:String; 
		
		public function Person()
		{
		}
	}
}
