SpringActionscript3 片断

主要的两个类：

1，FlexXMLApplicationContext，XMLApplicationContext，是IOC容器的两个重要类，FlexXMLApplicationContext只是增加了一些flex方面的特性。

2，定义文件模板：

    <?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-1.0.xsd">
         
    <object id="..." class="...">
    <!-- collaborators and configuration for this object go here -->
    </object>
    <object id="..." class="...">
    <!-- collaborators and configuration for this object go here -->
    </object>

    <!-- more object definitions go here -->
    </objects>

3，初始化容器：

　　var applicationContext:XMLApplicationContext = new XMLApplicationContext();

　　applicationContext.addConfigLocation("application-context.xml");
　　applicationContext.addEventListener(Event.COMPLETE, handleComplete);
　　applicationContext.load();

　　application-context.xml路径也可以通过FlashVars来设置

４，组合xml文件定义

　　<import file="services.xml"/>
    　<import file="resources/messageSource.xml"/>
   　 <import file="/resources/themeSource.xml"/>

５，绑定xml数据

      [Bindable]
      [Embed(source="application-context.xml",mimeType ="application/octet-stream")]
      public var contextConfig:Class;

     

      var applicationContext:XMLApplicationContext= new XMLApplicationContext();
     applicationContext.addEmbeddedConfig(contextConfig);
     applicationContext.load();

6, 绑定组合ｘｍｌ

　　[Bindable]
　　[Embed(source="services.xml",mimeType ="application/octet-stream")]
　　public var servicesContext:Class;

　　[Bindable]
　　[Embed(source="resources/messageSource.xml",mimeType ="application/octet-stream")]
　　public var messageSourceContext:Class;

　　[Bindable]
　　[Embed(source="/resources/themeSource.xml",mimeType ="application/octet-stream")]
　　public var themeSourceContext:Class;

　　　

　　<objects>

    　　　<import file="servicesContext" type="class"/>
    　　　<import file="messageSourceContext" type="class"/>
    　　　<import file="themeSourceContext" type="class"/>

    　　　<object id="object1" class="..."/>
   　　　 <object id="object2" class="..."/>

　　</objects>

７，定义属性文件：

　　　 <property file="strings.properties" />
　　　通过${...} 语法来访问。

８，释放容器管理对象

　　（１）实现IDisposable接口，

               public interface IDisposable {
                    function get isDisposed():Boolean;
                    function dispose():void;
              }

　　（２）在配置文件上制定destroy-method.

9, 实例化对象：

　　

１０，静态工厂实例化

　　　

<object id="exampleObject"
      class="examples.ExampleObjectLocator"
      factory-method="getInstance"/>

或者

<object id="exampleFactory"
      class="examples.ExampleObjectFactory"/>

<object id="exampleObject" class="examples.Example"
      factory-object="exampleFactory"
      factory-method="getInstance"/>
And for this the Actionscript equivalent would be:
var exampleFactory:ExampleObjectFactory = new ExampleObjectFactory();

var exampleObject:ExampleObject = exampleFactory.getInstance();

<object id="exampleObject" class="examples.ExampleObject"/>

	<object name="anotherExample" class="examples.ExampleObjectTwo"/>

　　　　　The Actionscript equivalent of which would be:

　　　　　　var exampleObject:ExampleObject;

　　　　　　var anotherExample:ExampleObjectTwo;

var exampleObject:ExampleObject = applicationContext.getObject("exampleObject") as ExampleObject;

Which in regular Actionscript would look like this:

var exampleObject:ExampleObject = new ExampleObject();
