我正在讨论Sanderson的Pro ASP.NET MVC框架,在第4章他讨论了
Creating a Custom Controller Factory,看来用于注册控制器的原始方法AddComponentLifeStyle或AddComponentWithLifeStyle现在已被弃用:
public class WindsorControllerFactory : DefaultControllerFactory { IWindsorContainer container; public WindsorControllerFactory() { container = new WindsorContainer(new XmlInterpreter(new ConfigResource("castle"))); // register all the controller types as transient var controllerTypes = from t in Assembly.GetExecutingAssembly().GetTypes() where typeof(IController).IsAssignableFrom(t) select t; //[Obsolete("Use Register(Component.For<I>().ImplementedBy<T>().Named(key).Lifestyle.Is(lifestyle)) instead.")] //IWindsorContainer AddComponentLifeStyle<I,T>(string key,LifestyleType lifestyle) where T : class; foreach (Type t in controllerTypes) { container.Register(Component.For<IController>().ImplementedBy<???>().Named(t.FullName).LifeStyle.Is(LifestyleType.Transient)); } } // Constructs the controller instance needed to service each request protected override IController GetControllerInstance(Type controllerType) { return (IController)container.Resolve(controllerType); } }
新的建议是使用Register(Component.For< I>().ImplementedBy< T>().Named(key).Lifestyle.Is(lifestyle)),但我无法弄清楚如何呈现实现控制器输入ImplementedBy< ???>()方法.我尝试了ImplementedBy< t>()和ImplementedBy< typeof(t)>(),但我找不到传递实现类型的适当方法.有任何想法吗?
解决方法
我正在使用
ControllerBuilder.SetControllerFactory
以及您可以在开源项目
MvcContrib中找到的代码执行此操作:
的Global.asax.cs
protected void Application_Start() { ... IWindsorContainer windsorContainer = new WindsorContainer(); windsorContainer.RegisterControllers(Assembly.GetExecutingAssembly()); ControllerBuilder.Current.SetControllerFactory(new WindsorControllerFactory(windsorContainer)); ... }
WindsorControllerFactory
public class WindsorControllerFactory : DefaultControllerFactory { private readonly IWindsorContainer _container; public WindsorControllerFactory(IWindsorContainer container) { if (container == null) { throw new ArgumentNullException(); } _container = container; } protected override IController GetControllerInstance(RequestContext requestContext,Type controllerType) { if (controllerType == null) { throw new HttpException(); } if (!typeof(IController).IsAssignableFrom(controllerType)) { throw new ArgumentException(); } try { return (IController)_container.Resolve(controllerType); } catch (Exception ex) { throw new InvalidOperationException(); } } public override void ReleaseController(IController controller) { IDisposable disposable = controller as IDisposable; if (disposable != null) { disposable.Dispose(); } _container.Release(controller); } }
WindsorExtensions(见MvcContrib)
public static class WindsorExtensions { public static IWindsorContainer RegisterController<T>(this IWindsorContainer container) where T : IController { container.RegisterControllers(typeof(T)); return container; } public static IWindsorContainer RegisterControllers(this IWindsorContainer container,params Type[] controllerTypes) { foreach (Type type in controllerTypes) { if (ControllerExtensions.IsController(type)) { container.Register(Component.For(type).Named(type.FullName).LifeStyle.Is(LifestyleType.Transient)); } } return container; } public static IWindsorContainer RegisterControllers(this IWindsorContainer container,params Assembly[] assemblies) { foreach (Assembly assembly in assemblies) { container.RegisterControllers(assembly.GetExportedTypes()); } return container; } }
ControllerExtensions(见MvcContrib)
public static class ControllerExtensions { public static bool IsController(Type type) { return type != null && type.Name.EndsWith("Controller",StringComparison.OrdinalIgnoreCase) && !type.IsAbstract && typeof(IController).IsAssignableFrom(type); } }
