需要將Castle.Windsor作為Asp.Net MVC ControllerFactory的幫助

Question

我正在嘗試從他的親Asp.Net MVC框架書（很棒的書，btw）中實現史蒂文·桑德森的WinsorControllerFactory，而我正陷入一個問題。 我不確定您還需要知道什么才能提出回應，但對此我將不勝感激。 謝謝！

這是代碼：

溫莎控制器工廠

public class WindsorControllerFactory : DefaultControllerFactory
{
    private WindsorContainer _container;

    public WindsorControllerFactory()
    {
        _container= new WindsorContainer(new XmlInterpreter(new ConfigResource("castle")));
        var controllerTypes = from t in Assembly.GetExecutingAssembly().GetTypes()
                              where typeof (IController).IsAssignableFrom(t)
                              select t;
        foreach(Type t in controllerTypes)
        {
            _container.AddComponentLifeStyle(t.FullName, t, LifestyleType.Transient);
        }
    }
    protected override IController GetControllerInstance(Type controllerType)
    {
        return (IController)_container.Resolve(controllerType);
    }
}

Web配置

  <castle>
    <components>
      <component id="MenuRepository"
                 service="****.IMenuRepository, ****.Model"
                 type="****.FakeMenuRepository, ****.Model">
      </component>
      <component id="NewsRepository"
                 service="****.INewsRepository, ****.Model"
                 type="****.FakeNewsRepository, ****.Model">
      </component>
    </components>
  </castle>

新聞ArticleController

public class NewsArticleController : Controller
{
    private INewsRepository _repository { get; set; }
    public NewsArticleController(INewsRepository repository)
    {
        _repository = repository;
    }

Global.asax

    protected void Application_Start()
    {
        RegisterRoutes(RouteTable.Routes);
        ControllerBuilder.Current.SetControllerFactory((new WindsorControllerFactory()));
    }

錯誤消息找不到支持該服務的組件****。NewsArticleController描述：執行當前Web請求期間發生未處理的異常。 請查看堆棧跟蹤，以獲取有關錯誤及其在代碼中起源的更多信息。

Exception Details: Castle.MicroKernel.ComponentNotFoundException: No component for supporting the service ****.NewsArticleController was found

S＃arpArchitecture項目可以將Windsor用作DI框架（用於控制器或其他任何東西），幾乎不需要添加web.config部分-http: //code.google.com/p/sharp-建築/

代碼示例：

CastleWindsor / ComponentRegistrar.cs：

public class ComponentRegistrar
{
    public static void AddComponentsTo(IWindsorContainer container) {
        AddGenericRepositoriesTo(container);
        AddCustomRepositoriesTo(container);

        container.AddComponent("validator",
            typeof(IValidator), typeof(Validator));
    }

    private static void AddCustomRepositoriesTo(IWindsorContainer container) {
        container.Register(
            AllTypes.Pick()
            .FromAssemblyNamed("Northwind.Data")
            .WithService.FirstNonGenericCoreInterface("Northwind.Core"));
    }

    private static void AddGenericRepositoriesTo(IWindsorContainer container) {
        container.AddComponent("entityDuplicateChecker",
            typeof(IEntityDuplicateChecker), typeof(EntityDuplicateChecker));
        container.AddComponent("repositoryType",
            typeof(IRepository<>), typeof(Repository<>));
        container.AddComponent("nhibernateRepositoryType",
            typeof(INHibernateRepository<>), typeof(NHibernateRepository<>));
        container.AddComponent("repositoryWithTypedId",
            typeof(IRepositoryWithTypedId<,>), typeof(RepositoryWithTypedId<,>));
        container.AddComponent("nhibernateRepositoryWithTypedId",
            typeof(INHibernateRepositoryWithTypedId<,>), typeof(NHibernateRepositoryWithTypedId<,>));
    }
}

Global.asax（di的主要初始化方法）：

protected virtual void InitializeServiceLocator() {
        IWindsorContainer container = new WindsorContainer();
        ControllerBuilder.Current.SetControllerFactory(new WindsorControllerFactory(container));

        container.RegisterControllers(typeof(HomeController).Assembly);
        ComponentRegistrar.AddComponentsTo(container);

        ServiceLocator.SetLocatorProvider(() => new WindsorServiceLocator(container));
    }

MvcContrib提供了一些擴展方法，用於在Windsor中注冊控制器，例如：

windsorContainer.RegisterControllers(Assembly.GetExecutingAssembly());

Mannish的代碼使用相同的擴展方法。

不要忘記WindsorControllerFactory上的ReleaseController函數，否則您的工作進程將耗盡內存，因為未釋放控制器。
