StructureMap異常202沒有定義默認實例（版本2.61）

Question

初始化容器的：

public override void Initialize() 
     { 

      ObjectFactory.Initialize(x => 
             { 
              x.Scan(s => 
                 { 
                  s.TheCallingAssembly(); 
                  s.AssemblyContainingType<IRegistar>(); 
                  s.WithDefaultConventions(); 

                 }); 

             }); 

     } 

Global.asax.xc

var dependencyContainer = new DependencyContainer(); 
      dependencyContainer.Initialize(); 

      ControllerBuilder.Current.SetControllerFactory(new DependencyControllerFactory()); 

的獲取實例：

public class DependencyControllerFactory : DefaultControllerFactory 
{ 
protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) 
     { 
      if (controllerType == null) 
      { 
       return base.GetControllerInstance(requestContext, controllerType); 
      } 

      try 
      { 
       return ObjectFactory.GetInstance(controllerType) as Controller; 
      } 
      catch (StructureMapException exception) 
      { 
       Debug.WriteLine(ObjectFactory.WhatDoIHave()); 
       throw; 
      } 
     } 
    } 

控制器

私人IBabyRepository _babyReposoitory; {

public BabyController(IBabyRepository babyRepository) 
    { 
     _babyReposoitory = babyRepository; 
    } 

類試圖DI/Ioc的

public class BabyRepository : IBabyRepository, IRepository<Baby>, IRegistar 
{ 
    Just a Default constructor here(); 
    code... 
} 

的錯誤：

StructureMap異常代碼：202 沒有默認實例PluginFamily Domain.Repository.IBabyRepository定義，域，版本= 1.0.0.0，文化=中立，PublicKeyToken = null

我在做什麼錯？

你不告訴StructureMap如何創建BabyRepository。

我覺得您的掃描需要是這樣的：

 Scan(y => 
     { 
      y.AssemblyContainingType<IRegistar>(); 
      y.Assembly(Assembly.GetExecutingAssembly().FullName); 
      y.With(new RepositoryScanner()); 
     }) 

然後需要編寫了自定義RepositoryScanner：

public class RepositoryScanner : IRegistrationConvention 
{ 
    public void Process(Type type, Registry registry) 
    { 
     if (type.BaseType == null) return; 

     if (type.GetInterface(typeof(IRepository).Name) != null) 
     { 
      var name = type.Name; 

      registry 
       .For<IRepository>() 
       .AddInstances(y => y.Instance(new ConfiguredInstance(type).Named(name))); 
     } 
    } 
}
