外部控制器和城堡

Question

已修复：如果其他 Joe Schmo 需要它，我会留下它。

在控制器工厂中，您需要注册控制器，以便在调用时可以找到它。 container.Kernel.AddComponent("ExternalResources", typeof(InteSoft.Web.ExternalResourceLoader.ExternalResourceController), LifestyleType.Transient); 这样做：

// 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,
            LifestyleType.Transient);

        // Register controllers in external assemblies
        container.Kernel.AddComponent("ExternalResources", typeof(InteSoft.Web.ExternalResourceLoader.ExternalResourceController), LifestyleType.Transient);

我正在使用MVC Resource loader 来压缩和缩小我的 CSS 和 JS。我还使用 WindsorControllerFactory 进行依赖注入。 MVC 资源加载器使用位于 InteSoft.Web.ExternalResourceLoader 命名空间中的控制器，该命名空间位于单独的程序集中。

问题似乎是 Castle 无法找到（并解决）该控制器，因为它位于不同的程序集中。我对 DI 和 Castle 还很陌生，所以我什至不知道从哪里开始。

城堡配置文件

<component id="MVCResourceLoader"
             service="System.Web.Mvc.ITempDataProvider, System.Web.Mvc"
             type="InteSoft.Web.ExternalResourceLoader.NullTempDataProvider, InteSoft.Web.ExternalResourceLoader"
             lifestyle="PerWebRequest">           
</component>

温莎控制器工厂

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,
            LifestyleType.Transient);

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

如果我需要提供更多调试信息，请告诉我。

更新 如果我直接访问 url，它会返回压缩文件，例如http://localhost:3826/Shared/ExternalResource?name=MinScript&version=20080811&display=Show

Answer 1

很可能 NullTempDataProvider 所在的程序集是 InteSoft.Web 而不是 InteSoft.Web.ExternalResourceLoader。如果是这种情况，注册应该是：

<component id="MVCResourceLoader"
             service="System.Web.Mvc.ITempDataProvider, System.Web.Mvc"
             type="InteSoft.Web.ExternalResourceLoader.NullTempDataProvider, InteSoft.Web"
             lifestyle="PerWebRequest">           
</component>

Answer 2

仅供参考，这是我使用 Castle 的 ControllerFactory：

Why is Castle Windsor trying to resolve my 'Content' and 'Scripts' folder as a controller?

请注意，我使用的是 Assembly.GetCallingAssembly().GetTypes()，因为我的自定义 ControllerFactory 位于单独的程序集中。如果是放在主mvc项目中，改成getExecutingAssembly()即可。

Answer 3

我认为您无法通过调用Assembly.GetExecutingAssembly().GetTypes() 在外部组件中获得服务。

尝试使用Assembly.LoadFrom("Assembly_Name")，然后用"ExternalResources"注册组件。
