最终效果：



首先把 flex_security.swc 放进你项目的lib文件中。

 

如图：


 

 

四种权限控制方式：

 

 

1. styleName

 

 

<?xml version="1.0" encoding="utf-8"?>
<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" 
			   width="100%" height="100%"
			   viewSourceURL="http://code.google.com/p/flex-security/source/browse/trunk/flex_security_demo/src/helloworld_by_styleName.mxml"
			   creationComplete="creationComplete()">
	<s:layout>
		<s:VerticalLayout horizontalAlign="center"/>
	</s:layout>
	<fx:Script>
		<![CDATA[
			import cn.org.rapid_framework.flex_security.SecurityControler;
			
			import mx.collections.ArrayCollection;
			import mx.events.FlexEvent;

			[Bindable]
			private var permissionList : Array = ['cc','sq','lb','ta_input'];
			
			protected function creationComplete():void
			{
				//启动权限控制
				SecurityControler.start(null,'visible');
			}

		]]>
	</fx:Script>
	
	<s:HGroup>
		<mx:HBox>
			<mx:ComboBox id="permInput" dataProvider="{permissionList}"/>
			<mx:Button click="SecurityControler.addPerm(permInput.selectedLabel)" label="添加权限" />
			<mx:Button click="SecurityControler.removePerm(permInput.selectedLabel)" label="移除权限" />
			<mx:Button click="SecurityControler.addAllPerms(new ArrayCollection(permissionList))" label="添加所有权限" />
			<mx:Button click="SecurityControler.removeAllPerms()" label="移除所有权限" />	
		</mx:HBox>
	</s:HGroup>
	
	<s:HGroup>
		<!-- 通过styleName增加需要权限保护的组件,没有权限将不能进行相关操作 -->
		<mx:HBox>
			<!-- id要和声明的对应,enabled表示显现出来，由于受到权限的控制，不可启用-->
			<mx:Button label="曹操" id="cc" styleName="security(null,enabled)" />
			<!-- 没有声明id，那么在security内要写上 -->
			<mx:Button label="孙权" styleName="security(sq)"/>
			<!-- 注意这个remove属性，这里声明了remove，那么下面的组件就不受security的控制而会显现出来了 -->
			<mx:Button label="刘备" styleName="security(lb,remove)"/>
			<!-- 这个算是容易点的写法吧 -->
			<mx:TextArea id="ta_input" styleName="security"/>
		</mx:HBox>
	</s:HGroup>
</s:Application>

	</s:HGroup>
	
	<s:HGroup>
		<!-- 被权限控制的按钮,没有权限将看不见下面的相关按钮 -->
		<mx:HBox>
			<!-- 看见没有，主要还是id和permissionList声明的对应 -->
			<mx:Button label="曹操" id="cc"/>

插件内部的SecurityActionCache是个单例模式，其类变量actions引用了外部定义的对象，且没有释放，导致外部对象不需要再使用的时候，无法垃圾回收，最终导致该对象的所有父对象也无法回收，使程序崩溃，希望插件开发者能考虑下这个问题


呵呵，学习了，这个Demo我是参考http://code.google.com/p/flex-security/source/browse/trunk/flex_security_demo/src/helloworld_by_annotation.mxml 这份文档的。可能是因为demo的关系吧，所以没完美处理。

这个插件用了静态方法，并给方法内部赋对象，使得该对象引用无法释放，存在很严重的内存泄露问题
