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();
对象配置:
[Component(id="roleDataTemplateManager",initMethod="initialize")]
public class RoleDataTemplateManager implements IResourceLoader
{
[Autowired]
public var resourceManager:ResourceManager;
public function initialize():void
{
resourceManager.register(this);
}
}
注意注入进去的对象必须是public,否则注不进去。
var configManager:ConfigManager=context.getObject("configManager");
2.3 如何注入第三方库中的对象
[Configuration]
public final class AppConfig {
public var stageAutowireProcessor:DefaultAutowiringStageProcessor;
public var eventHandlerMetadataProcessor:EventHandlerMetadataProcessor;
public var routeEventsMetadataProcessor:RouteEventsMetaDataProcessor;
}
