ASP.NET MVC 範例專案「Suteki.Shop」分析：Castle Windsor IOC 容器整合

專案採用 Castle Windsor 實現控制反轉（IOC），核心概念：

• Container：微核心掃描類別依賴並自動注入。
• Component：實作服務介面的具體類別。
• Service：介面契約，支援多實作切換。
• Facilities：擴充容器功能（如交易、啟動器）。

啟動初始化：Global.asax

protected void Application_Start() {
  RouteManager.RegisterRoutes(RouteTable.Routes);
  InitializeWindsor();
}
protected virtual void InitializeWindsor() {
  if (container == null) {
    container = ContainerBuilder.Build("Configuration\\Windsor.config");
    WcfConfiguration.ConfigureContainer(container);
    ServiceLocator.SetLocatorProvider(() => container.Resolve<IServiceLocator>());
    ControllerBuilder.Current.SetControllerFactory(new WindsorControllerFactory(container));
  }
}

ContainerBuilder.Build 註冊重點

public static IWindsorContainer Build(string configPath) {
  var container = new WindsorContainer(new XmlInterpreter(configPath));
  container.Kernel.AddHandlerSelector(new UrlBasedComponentSelector(
    typeof(IBaseControllerService), typeof(IImageFileService), typeof(IConnectionStringProvider)));
  container.Register(AllTypes.Of<Controller>().FromAssembly(Assembly.GetExecutingAssembly())
    .Configure(c => c.LifeStyle.Transient.Named(c.Implementation.Name.ToLower())));
  container.Register(
    Component.For<IUnitOfWorkManager>().ImplementedBy<LinqToSqlUnitOfWorkManager>().LifeStyle.Transient,
    Component.For<IFormsAuthentication>().ImplementedBy<FormsAuthenticationWrapper>(),
    Component.For<IServiceLocator>().Instance(new WindsorServiceLocator(container)),
    Component.For<AuthenticateFilter>().LifeStyle.Transient,
    Component.For<UnitOfWorkFilter>().LifeStyle.Transient,
    Component.For<DataBinder>().LifeStyle.Transient,
    Component.For<LoadUsingFilter>().LifeStyle.Transient,
    Component.For<CurrentBasketBinder>().LifeStyle.Transient,
    Component.For<ProductBinder>().LifeStyle.Transient,
    Component.For<OrderBinder>().LifeStyle.Transient,
    Component.For<IOrderSearchService>().ImplementedBy<OrderSearchService>().LifeStyle.Transient,
    Component.For<IEmailBuilder>().ImplementedBy<EmailBuilder>().LifeStyle.Singleton
  );
  return container;
}

展示了 Controller 自動註冊、Filter/Binder 作為 Component 註冊、ServiceLocator 橋接等進階 IOC 應用模式。
