AS3 IOC框架Spring Actionscript 的使用總結

Spring Actionscript 是衆多圍繞依賴注入提供解決方案的Flex控制反轉框架之一

AS3 下經典的IOC框架有Spring ActionScript、Parsley、Flicc和Swiz，因爲我對JAVA spring IOC機制較爲熟悉，因此選擇了 Spring ActionScript。

主要有XML配置（XML）和註釋元數據（Metadata）配置兩種方式，下面一一介紹，例子是基於spring AS 2.0.1版本展開的。--流子

1.從Spring Actionscript 主頁下載依賴包 

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

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

另有as3commons依賴包須要下載。建議下載這個 

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"/> 構造函數時引入 -->
	</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>

 

程序載入：

 

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

 

對容器中對象讀取:

 

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

2.2 註釋元數據（Metadata）配置方式

 

優勢:把application-context.xml 徹底幹掉，徹底經過註釋方式實現。它是對加載進來的SWF文件進行類掃描把[Component] 或者[Configuration] 讀取並解析進IOC容器。

 

首先，要添加編譯參數 -keep-as3-metadata+=Component,Invoke,Inject,Autowired

程序載入：

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

對象配置:

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

注意注入進去的對象必須是public,不然注不進去。

對象讀取:

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

2.3 如何注入第三方庫中的對象

建立一個對象，好比AppConfig

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