Question

我正在尝试从他的专业Asp.Net MVC框架书（伟大的书，顺便说一句）中实现Steven Sanderson的WinsorControllerFactory，我陷入了一个问题。我不确定为了制定回复你还需要知道什么，但我非常感谢你提供帮助。谢谢！

以下是代码：

WindsorControllerFactory

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);
    }
}

的Web.Config

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

NewsArticleController

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

Global.asax中

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

错误消息 没有用于支持服务的组件****。发现了NewsArticleController 描述：执行当前Web请求期间发生未处理的异常。请查看堆栈跟踪，以获取有关错误及其在代码中的起源位置的更多信息。

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

Source Error:

Line 29:         protected override IController GetControllerInstance(Type controllerType)
Line 30:         {
Line 31:             return (IController)_container.Resolve(controllerType);
Line 32:         }
Line 33:     }

S＃arpArchitecture项目可以很好地使用Windsor作为DI框架（用于控制器或其他任何东西），很少或根本不需要添加web.config部分 - http://code.google.com/p/sharp-architecture/

代码示例：

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));
    }

Answer 2

MvcContrib提供了一些在Windsor中注册控制器的扩展方法，例如：

windsorContainer.RegisterControllers(Assembly.GetExecutingAssembly());

Mannish的代码使用相同的扩展方法。

Answer 3

不要忘记WindsorControllerFactory上的ReleaseController函数，否则你的工作进程将耗尽内存，因为控制器没有被释放。

需要帮助Castle.Windsor作为Asp.Net MVC ControllerFactory
