ASP.Net : Unity Dependency Injection은 컨트롤러에서 예외를 throw합니다.

Question

기본적으로 제목에서 말하는 내용입니다.

https://github.com/dsidirop/PetTrackerOAuth.git 

단지 (전체 예외가 마지막에 표시됩니다)를 asp.net 스택 내부 예외로 인해 인스턴스를 결코 극복 컨트롤러 :

[RoutePrefix("api/account")] 
public sealed class AccountController : BaseApiController 
{ 
    private IPetTrackerUnitOfWork _repo; 

    public AccountController(IPetTrackerUnitOfWork repo) //this one isn't even getting called 
    { 
     _repo = repo; // System.Web.Mvc.DependencyResolver.Current.GetService(typeof(IPetTrackerUnitOfWork)); //strangely this works just fine 
    } 
} 

유니티 구성 여기에 전체 GitHub의 프로젝트입니다 :

[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(UnityWebActivator), nameof(UnityWebActivator.Start))] 
    [assembly: WebActivatorEx.ApplicationShutdownMethod(typeof(UnityWebActivator), nameof(UnityWebActivator.Shutdown))] 

    namespace AngularJSAuthentication.API.Unity 
    { 
    static public class UnityWebActivator 
    { 
      static public void Start() => StartWithSpecifiedConnection(); 
      static public void StartWithSpecifiedConnection(Type typeOfDbContextToUse = null) 
      { 
       var configuredUnityContainer = ((ConfiguredUnityContainer) ConfiguredUnityContainer.I).Init(typeOfDbContextToUse); 

       FilterProviders.Providers.Remove(FilterProviders.Providers.OfType<FilterAttributeFilterProvider>().First()); 
       FilterProviders.Providers.Add(new UnityFilterAttributeFilterProvider(configuredUnityContainer)); 

       GlobalConfiguration.Configuration.DependencyResolver = new global::Unity.WebApi.UnityDependencyResolver(configuredUnityContainer); 
       DynamicModuleUtility.RegisterModule(typeof(UnityPerRequestHttpModule)); 
      } 

      static public void Shutdown() => ConfiguredUnityContainer.I.Dispose(); 
    } 

    public class ConfiguredUnityContainer : UnityContainer 
    { 
     static public IUnityContainer I => _lazyInstance.Value; 

     static private readonly Lazy<IUnityContainer> _lazyInstance = new Lazy<IUnityContainer>(() => new ConfiguredUnityContainer()); 

     private ConfiguredUnityContainer() 
     { 
     } 

     public IUnityContainer Init(Type typeOfDbContextToUse = null) 
     { 
      this.RegisterType(typeof(IPetTrackerDbContext), typeOfDbContextToUse ?? typeof(PetTrackerDbContextProduction), new PerRequestLifetimeManager()); 
      this.RegisterType<IPetTrackerDbContext, PetTrackerDbContextProduction>(new PerRequestLifetimeManager()); 
      this.RegisterType<IPetTrackerDbContext, PetTrackerDbContextProduction>(new PerRequestLifetimeManager()); 
      this.RegisterType<IPetTrackerUnitOfWork, PetTrackerUnitOfWork>(new PerRequestLifetimeManager()); 
      this.RegisterType<IUserStore<IdentityUser>, PetTrackerUserStore>(new PerRequestLifetimeManager()); 
      this.RegisterType<IRoleStore<IdentityRole, string>, PetTrackerRoleStore>(new PerRequestLifetimeManager()); 
      this.RegisterType<IPetTrackerRoleManager, PetTrackerRoleManager>(new PerRequestLifetimeManager()); 
      this.RegisterType<IPetTrackerUserManager, PetTrackerUserManager>(new PerRequestLifetimeManager()); 
      this.RegisterType<IPetTrackerUserRepository, PetTrackerUserRepository>(new PerRequestLifetimeManager()); 
      this.RegisterType<IPetTrackerRoleRepository, PetTrackerRoleRepository>(new PerRequestLifetimeManager()); 
      this.RegisterType(typeof(IRepository<>), typeof(GenericRepository<>), new PerRequestLifetimeManager()); 
      this.RegisterInstance(typeof(HttpConfiguration), GlobalConfiguration.Configuration);

당신이 프로젝트 당신이 게시 한로받은 예외를 실행하려고 다운로드. 현재 우리는 IOC의 컨테이너로 유니티를 사용하는

. IoC 컨테이너는 컨트롤러 클래스의 초기화를 처리합니다. 컨트롤러의 인스턴스를 생성하는 IoC 컨테이너를 만들려면, 컨트롤러 클래스는 매개 변수없는 public 생성자가 필요 - 때 이제 기본 생성자 우리는 아래에 추가 할 필요가

,

public AccountController() : base() { } 

를 I 내가 라인 (44)에, 아래 점점 제외하고 실행하려고 - 등록 블록
