Asp.net mvc 使用Unity错误在ASP.NET Web API中进行依赖项注入

我试图按照Unity实现依赖注入，但我在boostrapper.cs（我使用Unity.MVC4库）中遇到了一个错误。有人能告诉我我缺少什么吗

错误：IoCContainer不存在 似乎实施 Microsoft.Practices.ServiceLocation.IServiceLocator。参数名称： 公共服务提供者

这是IoCContainer类

public class ScopeContainer : IDependencyScope
    {
        protected IUnityContainer container;

        public ScopeContainer(IUnityContainer container)
        {
            if (container == null)
            {
                throw new ArgumentNullException("container");
            }
            this.container = container;
        }

        public object GetService(Type serviceType)
        {
            if (container.IsRegistered(serviceType))
            {
                return container.Resolve(serviceType);
            }
            else
            {
                return null;
            }
        }

        public IEnumerable<object> GetServices(Type serviceType)
        {
            if (container.IsRegistered(serviceType))
            {
                return container.ResolveAll(serviceType);
            }
            else
            {
                return new List<object>();
            }
        }

        public void Dispose()
        {
            container.Dispose();
        }
    }

    class IoCContainer : ScopeContainer, IDependencyResolver
    {
        public IoCContainer(IUnityContainer container)
            : base(container)
        {
        }

        public IDependencyScope BeginScope()
        {
            var child = container.CreateChildContainer();
            return new ScopeContainer(child);
        }
    }

我也有一种感觉，它可能与路由有关，我实际上在配置中添加了经典的MVC路由，因为我读到webapi和MVC使用不同的“激活器”之类的东西

 public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

            config.Routes.MapHttpRoute(
              name: "RestApi",
              routeTemplate: "api/{controller}/{action}/{id}",
              defaults: new { id = RouteParameter.Optional }
            );

找到了答案，看起来博客已经过时了，因为我甚至不需要创建IoCContainer，因为我只需要安装

Unity.WebAPI

，然后将

DependencyResolver

设置为

new Unity.WebAPI.UnityDependencyResolver（容器）

信用证：
并删除所有直接无关的代码以使问题更清楚，请//这抛出“似乎没有实现Microsoft.Practices.ServiceLocation.IServiceLocator…错误”，同样值得Unity团队注意：和。因此，可以在控制器中使用GlobalConfiguration.Configuration.DependencyResolver吗？
protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();

            WebApiConfig.Register(GlobalConfiguration.Configuration);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);

            Bootstrapper.Initialise();
        }

 public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

            config.Routes.MapHttpRoute(
              name: "RestApi",
              routeTemplate: "api/{controller}/{action}/{id}",
              defaults: new { id = RouteParameter.Optional }
            );

public static class Bootstrapper
  {
    public static IUnityContainer Initialise()
    {
      var container = BuildUnityContainer();

      DependencyResolver.SetResolver(new UnityDependencyResolver(container));

      GlobalConfiguration.Configuration.DependencyResolver = new Unity.WebApi.UnityDependencyResolver(container);

      return container;
    }
