Spring Actionscript 是众多围绕依赖注入提供解决方案的Flex控制反转框架之一

AS3 下经典的IOC框架有Spring ActionScript、Parsley、Flicc和Swiz，由于我对JAVA
spring IOC机制较为熟悉，所以选择了 Spring ActionScript。

主要有XML配置（XML）和注释元数据（Metadata）配置两种方式，下面一一介绍，例子是基于spring AS 2.0.1版本展开的。--流子

1.从Spring
Actionscript 主页下载依赖包 

spring-actionscript-core-X.X.X.swc

spring-actionscript-flex-X.X.X.swc

另有as3commons依赖包需要下载。建议下载这个 

Spring
Actionscript X.X.X Full (with dependencies and Flex extensions)

2.1 XML配置方式

配置文件application-context.xml

<?xml version="1.0" encoding="UTF-8"?>
<objects xmlns="http://www.springactionscript.org/schema/objects"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springactionscript.org/schema/objects
	http://www.springactionscript.org/schema/objects/spring-actionscript-objects-2.0.xsd">
	<object id="ConfigManager" class="com.yimi.fairy.client.ConfigManager"
		init-method="initialize">
		<!--<constructor-arg ref="authenticationService"/> 构造函数时引入 -->
	</object>
	<object id="RoleManager" class="com.yimi.fairy.client.service.role.RoleManager"
		init-method="initialize">
		<property name="configManager" ref="ConfigManager" />
	</object>
	<object id="ResourceManager" class="com.yimi.fairy.client.res.ResourceManager"></object>
	<object id="JobManager" class="com.yimi.fairy.client.job.JobManager"></object>
	<object id="RoleDataTemplateManager" class="com.service.role.RoleDataTemplateManager">
	<constructor-arg ref="ResourceManager"/> 
	</object>
</objects>

程序载入：

var context:XMLApplicationContext=new XMLApplicationContext("application-context.xml");
context.addEventListener(Event.COMPLETE, this.handleComplete);  
context.load();  

对容器中对象读取:

var configManager:ConfigManager=context.getObject("ConfigManager");

2.2 注释元数据（Metadata）配置方式

优点:把application-context.xml 完全干掉，完全通过注释方式实现。它是对加载进来的SWF文件进行类扫描把[Component] 或者[Configuration] 读取并解析进IOC容器。

var rootViews:Vector.<DisplayObject> = new <DisplayObject>[display];
var context:MetadataApplicationContext= new MetadataApplicationContext(rootViews);
context.addEventListener(Event.COMPLETE, this.handleComplete);
context.load();

[Component(id="roleDataTemplateManager",initMethod="initialize")]
public class RoleDataTemplateManager implements IResourceLoader
{
	[Autowired]
	public var resourceManager:ResourceManager;
	public function initialize():void
	{
		resourceManager.register(this);
	}
}

var configManager:ConfigManager=context.getObject("configManager");

[Configuration]
public final class AppConfig {
	public var stageAutowireProcessor:DefaultAutowiringStageProcessor;
	public var eventHandlerMetadataProcessor:EventHandlerMetadataProcessor;
	public var routeEventsMetadataProcessor:RouteEventsMetaDataProcessor;
	}
