model-view-controller - SportsStore : MVC programming issue [CaSTLe WindsorControllerFactory]

Question

所以我一直在关注 Steven Sanderson 的名为 Pro ASP.NET MVC Framework 的书，但我遇到了一个异常:

No parameterless constructor defined for this object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.MissingMethodException: No parameterless constructor defined for this object.

Source Error:

Line 16:             HttpContext.Current.RewritePath(Request.ApplicationPath, false);
Line 17:             IHttpHandler httpHandler = new MvcHttpHandler();
Line 18:             httpHandler.ProcessRequest(HttpContext.Current);
Line 19:             HttpContext.Current.RewritePath(originalPath, false);
Line 20:         }

这是我的 WindsorControllerFactory 代码:

public class WindsorControllerFactory : DefaultControllerFactory
{
    WindsorContainer container;

    // The constructor
    // 1. Sets up a new IoC container
    // 2. Registers all components specified in web.config
    // 3. Registers all controller types as components
    public WindsorControllerFactory()
    { 
        // Instantiate a container, taking configuration from web.config
        container = new WindsorContainer(
                        new XmlInterpreter(new ConfigResource("castle"))
                    );

        // Also register all the controller types as transient
        var controllerTypes = from t in Assembly.GetExecutingAssembly().GetTypes()
                              where typeof(IController).IsAssignableFrom(t)
                              select t;

        foreach (Type t in controllerTypes)
            container.AddComponentWithLifestyle(t.FullName, t, Castle.Core.LifestyleType.Transient);
    }

    // Constructs the controller instance needed to service each request
    protected override IController GetControllerInstance(Type controllerType)
    {
        return (IController)container.Resolve(controllerType);
    }
}

我的 Global.asax.cs 代码:

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

和 web.config 值:

<configSections>
    <section name="castle"
             type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler,
                   Castle.Windsor"/>
</configSections>
<castle>
    <properties>
      <myConnStr>Server=.\SQLEXPRESS;Database=SportsStore;Trusted_Connection=yes;</myConnStr>
    </properties>
    <components>
      <component id="ProdsRepository"
                 service="DomainModel.Abstract.IProductsRepository, DomainModel"
                 type="DomainModel.Concrete.SqlProductsRepository, DomainModel">
        <parameters>
          <connectionString>#{myConnStr}</connectionString>
        </parameters>
      </component>
    </components>
</castle>

谢谢大家!

namespace WebUI
{
    public class WindsorControllerFactory:DefaultControllerFactory
    {
        WindsorContainer container;

        public WindsorControllerFactory()
        {
            container = new WindsorContainer(new XmlInterpreter(new ConfigResource("castle")));

            container.Register(AllTypes
                .FromThisAssembly()
                .BasedOn<IController>()
                .If(Component.IsInSameNamespaceAs<Controllers.ProductsController>())
                .If(t => t.Name.EndsWith("Controller"))
                .Configure(c=>c.LifeStyle.Transient.Named(c.Implementation.Name)));
        }

        protected override IController GetControllerInstance(RequestContext ctx, Type controllerType)
        {
            if (controllerType == null) { return null; }
            return (IController)container.Resolve(controllerType);            
        }
    }
 }
