Question

我正在尝试在我的解决方案中使用DI（即Castle Windsor），但我遇到以下异常：

No component for supporting the service Company.Web.Controllers.DashboardController was found

尝试解析控制器时WindsorControllerFactory.GetControllerInstance()发生此异常（即：(IController)_kernel.Resolve(controllerType);）

然而，当我将DI安装程序和控制器工厂移动到asp.net应用程序并让该Web项目引用我的解决方案中的所有项目时，不会发生异常。

问题：如何解决上面的异常并将依赖注入及其配置放入其自己的程序集中（即：Company.Initialization）？

请随意提供任何可以改进代码的建设性批评。

当前解决方案项目设置

Company.Initialization位于名为Company.Initialization的程序集中。这包含装配包含DI配置和Castle Windosr的参考。
Company.Initialization引用了每个程序集。
Company.Web位于名为Company.Web
Company.Web是一个ASP.NET MVC4应用程序。

ControllersInstaller.cs

namespace Company.Initialization
{
    public class ControllersInstaller : IWindsorInstaller
    {
        /// <summary>
        /// Installs the controllers
        /// </summary>
        /// <param name="container"></param>
        /// <param name="store"></param>
        public void Install(IWindsorContainer container, IConfigurationStore store)
        {
            container.Register(FindControllers().LifestyleTransient());
        }

        /// <summary>
        /// Find controllers within this assembly in the same namespace as HomeController
        /// </summary>
        /// <returns></returns>
        private BasedOnDescriptor FindControllers()
        {
            return AllTypes.FromAssemblyNamed("Company.Web")
                 .BasedOn<IController>()
                 .If(Component.IsInNamespace(@"Company.Web.Controllers"))
                 .If(t => t.Name.EndsWith("Controller"));

        }

    }
}

RepoInstaller.cs

namespace Company.Initialization
{
    public class RepoInstaller : IWindsorInstaller
    {

        public void Install(IWindsorContainer container, IConfigurationStore store)
        {
            container.Register(AllTypes.FromAssemblyNamed("Company.Services")
                .Where(type => type.Name.EndsWith("Service"))
                .WithService.DefaultInterfaces().LifestyleSingleton());

            container.Register(AllTypes.FromAssemblyNamed("Company.NHibernateProvider")
               .Where(type => type.Name.EndsWith("Repository"))
               .WithService.DefaultInterfaces().LifestyleSingleton());

        }
    }
}

WindsorControllerFactory.cs

namespace Company.Initialization
{
    public class WindsorControllerFactory : DefaultControllerFactory
    {
        private readonly IKernel _kernel;

        /// <summary>
        /// Constructor
        /// </summary>
        /// <param name="kernel"></param>
        public WindsorControllerFactory(IKernel kernel)
        {
            _kernel = kernel;
        }

        /// <summary>
        /// Release the controller at the end of it's life cycle
        /// </summary>
        /// <param name="controller">The Interface to an MVC controller</param>
        public override void ReleaseController(IController controller)
        {
            _kernel.ReleaseComponent(controller);
        }

        /// <summary>
        /// Resolve a controller dependency
        /// </summary>
        /// <param name="requestContext">The HTTP context</param>
        /// <param name="controllerType">Type of controller to resolve</param>
        /// <returns>IController</returns>
        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);
        }

    }
}
