我真的不明白我在这里做错了什么 - 由于某种原因,IControllerFactory我没有使用注册,我最终得到System.ArgumentException

类型“Company.WebApi.Controllers.AController”没有默认构造函数

在 System.Linq.Expressions.Expression.New(Type 类型) 在 System.Web.Http.Internal.TypeActivator.Create[TBase](Type instanceType) 在 System.Web.Http.Dispatcher.DefaultHttpControllerActivator.GetInstanceOrActivator(HttpRequestMessage 请求,类型在 System.Web.Http.Dispatcher.DefaultHttpControllerActivator.Create(HttpRequestMessage request, HttpControllerDescriptor controllerDescriptor, Type controllerType) 的 controllerType, Func`1& activator)

在 Global.asax.cs

protected void Application_Start()
{
    //DI-setup
    var container = new WindsorContainer().Install(new WebWindsorInstaller());

    //set custom controller factory
    var controllerFactory = container.Resolve<IControllerFactory>();
    ControllerBuilder.Current.SetControllerFactory(controllerFactory);

    //register cors
    container.Resolve<ICorsConfig>().RegisterCors(GlobalConfiguration.Configuration);

    //routes
    RegisterRoutes(RouteTable.Routes);
}

IControllerFactory的基于这篇文章http://keyvan.io/custom-controller-factory-in-asp-net-mvc实现如下

public class ControllerFactory : IControllerFactory
    {
        private readonly IWindsorContainer _container;

        public ControllerFactory(IWindsorContainer container)
        {
            if(container == null)
                throw new ArgumentNullException("container");

            _container = container;
        }

        public IController CreateController(RequestContext requestContext, string controllerName)
        {
            if (string.IsNullOrEmpty(controllerName))
                throw new ArgumentNullException("controllerName");

            var componentName = GetComponentNameFromControllerName(controllerName);

            return _container.Resolve<IController>(componentName);
        }

        public SessionStateBehavior GetControllerSessionBehavior(RequestContext requestContext, string controllerName)
        {
            throw new NotImplementedException();
        }

        public void ReleaseController(IController controller)
        {
            _container.Release(controller);
        }

        static string GetComponentNameFromControllerName(string controllerName)
        {
            var controllerNamespace = typeof (CrudController<>).Namespace;
            return string.Format("{0}.{1}Controller", controllerNamespace, controllerName);
        }
    }

我已经盯着这个看了好几个小时,真的不明白为什么这不起作用。调试时,ControllerFactory除了构造函数外,任何方法都不会命中。有人看到这里有什么问题或遗漏吗?

设置 ASP.NET MVC ControllerFactory 没有效果并不能回答我的问题)

            _installComplete = true;
        }

从您问题中的错误消息看来,您实际上想要注册 WebAPI 控制器。重要的是要注意这些与 MVC 控制器不同,并且不要使用相同的控制器工厂(您正在尝试使用)。

有关如何为 Web API 控制器执行此操作的详细信息,请参阅 Mark Seeman 的博文在 ASP.NET Web API 中使用 Castle Windsor 进行依赖注入。
