复杂工厂的介绍
如图所示，ArtifactProcessorExtensionPoint接口表明这是是个插件板，它有两个子插件板，分别为URLArtifactProcessorExtensionPoint 和StAXArtifactExtensionPoint，另外还有两个缺省实现类DefaultURLArtifactProcessorExtensionPoint 和 DefaultStAXArtifactExtensionPoint，从上面工厂类模式的扩展类似（为了简化，没有画文件包及处理文件的类ServiceConfigUtil），在META-INF/services/下面有两个文件：
org.apache.tuscany.sca.contribution.processor.URLArtifactProcessorExtensionPoint
org.apache.tuscany.sca.contribution.processor.DefaultURLArtifactProcessorExtensionPoint
org.apache.tuscany.sca.contribution.processor.StAXArtifactProcessorExtensionPoint
org.apache.tuscany.sca.contribution.processor.DefaultStAXArtifactProcessorExtensionPoint
分别标明是两个子插件板的实现插件板。它们都继承了DefaultArtifactProcessorExtensionPoint，也就是说提供类型（ArtifactProcessor）相似的插孔。更具体地说是继承类型（ArtifactProcessor的两个子类型URLArtifactProcessor和StAXArtifactProcessor），这儿可以很清楚地看出JDK1.5后的泛型的应用是多么大的威力。
同样在在META-INF/services/下面有两个相对应的文件，分别表示两种类似的插件：

类似上面所说明的，在Hash Map中依然是保存着ArtifactProcessor的延迟加载封装类，同样是采用代理模式来实现延迟加载功能的，在这儿不再赘述。
