StructureMap 是一个非常灵巧的IOC框架，与asp.net MVC 更是很好的集成。
准备：
下载StructureMap，基本实例中只需要引用StructureMap.dll文件，并引用命名空间StructureMap
下面是我们需要使用IoC的示例代码，我们要创建TestController，希望通过IoC为TestController的构造函数提供Ants.Provider.ICacheProvider的实例对象。
Step1:
用StructureMapControllerFactory代替默认的DefaultControllerFactory，以及StructureMap的初始化，并在Application_Start()进行注册。
