Question

我的网站是MVC和WebAPI的混合体。当我第一次加载网站时，似乎我的控制器正在我的IOC容器完全加载之前构建。我第一次调试网站时出现以下错误：

 An exception of type 'Microsoft.Practices.ServiceLocation.ActivationException' occurred in Microsoft.Practices.ServiceLocation.dll but was not handled in user code

 Additional information: Activation error occured while trying to get instance of type PendingCoursesController, key ""

我正在使用StructureMap作为我的容器，并从nuget中删除了包的'structuremap'和'StructureMap.MVC4'。抛出错误的控制器是WebAPI控制器。如果我刷新页面，则控制器构造正确，并且所有内容都按预期加载到页面上。这只是引发错误的初始加载，因此我的页面缺少数据。

public static class IoC {
    public static IContainer Initialize() {
        ObjectFactory.Initialize(x =>
                    {
                        x.Scan(scan =>
                                {
                                    scan.TheCallingAssembly();
                                    scan.WithDefaultConventions();
                                });
                    });
        return ObjectFactory.Container;
    }
}

[assembly: WebActivator.PreApplicationStartMethod(typeof(App_Start.StructuremapMvc), "Start")]
public static class StructuremapMvc {
    public static void Start() {
        IContainer container = IoC.Initialize();
        DependencyResolver.SetResolver(new StructureMapDependencyResolver(container));
        GlobalConfiguration.Configuration.DependencyResolver = new StructureMapDependencyResolver(container);
    }
}
