統一自動註冊類

Question

我正在使用Unity進行依賴注入。我有一堆以文本「Mapper」結尾的類，例如。

HomeMapper，ContactMapper，EmployeeMapper

目前即時通訊註冊這些類使用Unity作爲

conatiner.RegisterType<HomeMapper>; 
conatiner.RegisterType<ContactMapper>; 
conatiner.RegisterType<EmployeeMapper>; 

我想使用Unity的自動註冊功能來註冊與「映射」結束，這是所有類在某些組裝中。

我已經添加了參考`Unity.AutoRegistration.dll'程序集，但即時查找語法？

public class HomeMapper 
{ 
    private readonly MyService _service; 
    public HomeMapper(MyService service) 
    { 
     _service = service; 
    } 

    public MyModel Map(MyEntity entity) 
    { 
     // do mapping here 
    } 
} 

我可以註冊HomeMapper爲單身？注意它需要MyService實例作爲構造函數的參數和MyService被註冊爲

container.RegisterType<MyService, MyService>();

使用Unity你do not need to register具體類（不同於新的ASP.NET核心的依賴注入框架，所有registrations need to be explicit）。下面的測試成功創建了接收HomeMapper作爲一個依賴的HomeController的一個實例：

public class ResolveControllerTest 
{ 
    [Xunit.Fact] 
    public void ResolveHomeControllerWithoutRegistration() 
    { 
     var container = new UnityContainer(); 
     var controller = container.Resolve<HomeContoller>(); 
     Assert.NotNull(controller); // pass 
    } 
} 

public class HomeContoller 
{ 
    public HomeContoller(HomeMapper mapper) 
    { 
    } 
} 

public class HomeMapper 
{ 
} 

您可能要註冊的具體類，比如，當你需要定製的壽命。

編輯：

假設映射是無國籍，所有以「映射」可以註冊爲Singletones結束等級：

var container = new UnityContainer(); 
container.RegisterTypes(
    AllClasses.FromLoadedAssemblies() 
     .Where(t => t.Name.EndsWith("Mapper")), 
    WithMappings.None, 
    WithName.Default, 
    WithLifetime.ContainerControlled); 

// controllers are 'transient' - new instance per resolve 
var controller1 = container.Resolve<HomeContoller>(); 
var controller2 = container.Resolve<HomeContoller>(); 

// mapper is a singleton. Same instance returned 
var mapper1 = container.Resolve<HomeMapper>(); 
var mapper2 = container.Resolve<HomeMapper>();
