Question

我阅读了有关Casle Windsor的this文章。所以我有类BusinessLogicInstaller.cs，ControllersInstaller，IocContainer和WindsorControllerFactory。这是一个例子：

public class ControllersInstaller : IWindsorInstaller
{
    public void Install(IWindsorContainer container, IConfigurationStore store)
    {
        container.Register(AllTypes.FromThisAssembly()
            .Pick().If(t => t.Name.EndsWith("Controller"))
            .Configure(configurer => configurer.Named(configurer.Implementation.Name))
            .LifestylePerWebRequest());
    }
}

public class BusinessLogicInstaller : IWindsorInstaller
{
    public void Install(IWindsorContainer container, IConfigurationStore store)
    {
        container.Register(
            Component
            .For<IUser>()
            .ImplementedBy<User>());
    }
}

public static class IocContainer
{
    private static IWindsorContainer _container;

    public static void Setup()
    {
        _container = new WindsorContainer().Install(FromAssembly.This());

        WindsorControllerFactory controllerFactory = new WindsorControllerFactory(_container.Kernel);
        ControllerBuilder.Current.SetControllerFactory(controllerFactory);
    }
}

public class WindsorControllerFactory : DefaultControllerFactory
{
    private readonly IKernel _kernel;

    public WindsorControllerFactory(IKernel kernel)
    {
        this._kernel = kernel;
    }

    public override void ReleaseController(IController controller)
    {
        _kernel.ReleaseComponent(controller);
    }

    protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
    {
        if (controllerType == null)
        {
            throw new HttpException(404, string.Format("The controller for path '{0}' could not be found.", requestContext.HttpContext.Request.Path));
        }
        return (IController)_kernel.Resolve(controllerType);
    }
}

在Global.asax类我有

public class MvcApplication : HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);

        // Add this line to Application_Start in Global.asax.cs to setup the IoC Container.
        IocContainer.Setup();
    }
}

问题出在这行代码中的WindsorControllerFactory.cs类中：

return (IController)_kernel.Resolve(controllerType);

错误是没有组件支持服务Controllers.HomeController被找到。错误在哪里？

我找到了解决方案......首先，我没有提到我的MVC项目中的一个重大区别（因为我不知道为什么这么重要） - 我为控制器提供了单独的程序集。因此，ControllerInstallers.cs中的这部分代码出现了错误：

.FromThisAssembly()

应该是：

.FromAssemblyNamed("Controllers")

我要感谢@Jan Muncinsky，因为你的答案，以及你对一个问题所在的课程的暗示。

没有找到支持HomeController服务的组件 - Castle Windsor错误
