我在我的项目MVC4 Unity中有这个配置,并且在驱动程序中有一个通用的配置。
Bootstrapper.cs
namespace MyProyect.Web
{
public static class Bootstrapper
{
public static void Initialise()
{
var container = BuildUnityContainer();
ServiceLocator.SetLocatorProvider(() => new UnityServiceLocator(container));
DependencyResolver.SetResolver(new UnityDependencyResolver(container));
GlobalConfiguration.Configuration.DependencyResolver = new Unity.WebApi.UnityDependencyResolver(container);
}
private static IUnityContainer BuildUnityContainer()
{
var container = new UnityContainer();
container.RegisterType<MyProyect.Model.DataAccessContract.ICountryDao, MyProyect.DataAccess.CountryDao>();
container.RegisterType<MyProyect.Model.DataAccessContract.IContactDao, MyProyect.DataAccess.ContactDao>();
return container;
}
}
}
的Global.asax:
protected void Application_Start()
{
...
Bootstrapper.Initialise();
...
}
GenericModelBinder.cs:
namespace MyProyect.Web.ModelBinder
{
public class GenericModelBinder : DefaultModelBinder//, IValueProvider
{
protected override object CreateModel(ControllerContext controllerContext, ModelBindingContext bindingContext, Type modelType)
{
var resolver = (Unity.Mvc4.UnityDependencyResolver)DependencyResolver.Current;
if (modelType == null)
{
return base.CreateModel(controllerContext, bindingContext, null);
}
return resolver.GetService(modelType);
}
}
}
现在我需要解决解决方案中另一个项目的依赖关系。我的问题是如何识别Unity在另一个项目中的设置?我目前有这个类,但当前配置没有引入MVC项目。
namespace MyProyect.Model.ListData
{
public abstract class ListDataGenericResolver
{
protected T ResolverType<T>()
{
IUnityContainer container = new UnityContainer();
UnityServiceLocator locator = new UnityServiceLocator(container);
ServiceLocator.SetLocatorProvider(() => locator);
//return unity.Resolve<T>();
return (T)container.Resolve(typeof(T));
}
}
}
这是一个如何使用ListDataGenericResolver
:
namespace MyProyect.Model.ListData.Types
{
public class CountryListData : ListDataGenericResolver, IGetListData
{
private readonly ICountryDao countryDao;
private string defaultValue;
public CountryListData(object defaultValue)
{
// Resolver
this.countryDao = this.ResolverType<ICountryDao>();
this.defaultValue = defaultValue == null ? string.Empty : defaultValue.ToString();
}
public IList<SelectData> GetData()
{
var data = this.countryDao.GetAllCountry(new Entity.Parameters.CountryGetAllParameters());
return data.Select(d => new SelectData
{
Value = d.CountryId.ToString(),
Text = d.Description,
Selected = this.defaultValue == d.CountryId.ToString()
}).ToList();
}
}
}
谢谢。

我是这样做的。
在Application_Start中,我创建了Unity容器。我有一个自定义库,我用于我通过NuGet导入的所有MVC项目,因此我调用其configure方法,然后调用其他项目的Configure()方法。您可以简单地省略自定义库并在此处添加该代码。所有这些都使我的Application_Start变得干净整洁。
protected void Application_Start()
{
// Standard MVC setup
// <removed>
// Application configuration
var container = new UnityContainer();
new CompanyName.Mvc.UnityBootstrap().Configure(container);
new AppName.ProjectName1.UnityBootstrap().Configure(container);
new AppName.ProjectName2.UnityBootstrap().Configure(container);
// <removed>
}
这是自定义MVC库的UnityBootstrap类的代码
namespace CompanyName.Mvc
{
/// <summary>
/// Bootstraps <see cref="CompanyName.Mvc"/> into a Unity container.
/// </summary>
public class UnityBootstrap : IUnityBootstrap
{
/// <inheritdoc />
public IUnityContainer Configure(IUnityContainer container)
{
// Convenience registration for authentication
container.RegisterType<IPrincipal>(new InjectionFactory(c => HttpContext.Current.User));
// Integrate MVC with Unity
container.RegisterFilterProvider();
DependencyResolver.SetResolver(new UnityDependencyResolver(container));
return container;
}
}
}
然后,在其他项目中,我在那里有一个UnityBootstrap,它是从Application_Start调用的:
ProjectName1:
namespace AppName.ProjectName1
{
public class UnityBootstrap : IUnityBootstrap
{
public IUnityContainer Configure(IUnityContainer container)
{
return container.RegisterType<IDocumentRoutingConfiguration, DocumentRoutingConfiguration>();
}
}
}
ProjectName2: - 你可以在这里看到,这个依赖于另一个库中的其他一些项目,它正在调用它们的Configure()方法来设置它们......
namespace AppName.ProjectName2
{
public class UnityBootstrap : IUnityBootstrap
{
public IUnityContainer Configure(IUnityContainer container)
{
new CompanyName.Security.UnityBootstrap().Configure(container);
new CompanyName.Data.UnityBootstrap().Configure(container);
container.RegisterSecureServices<AuthorizationRulesEngine>(typeof(UnityBootstrap).Assembly);
return container
.RegisterType<IAuthorizationRulesEngine, AuthorizationRulesEngine>()
.RegisterType<IDateTimeFactory, DateTimeFactory>()
.RegisterType<IDirectoryInfoFactory, DirectoryInfoFactory>()
.RegisterType<IDirectoryWrapper, DirectoryWrapper>()
.RegisterType<IEmailService, EmailService>()
.RegisterType<IEntryPointService, EntryPointService>();
}
}
}
以下是整个上述代码中使用的IUnityBootstrap接口(供您参考)
/// <summary>
/// Defines a standard interface for bootstrapping an assembly into a Unity container.
/// </summary>
public interface IUnityBootstrap
{
/// <summary>
/// Registers all of the assembly's classes to their public interfaces and performs any other necessary configuration.
/// </summary>
/// <param name="container">The Unity container instance to configure.</param>
/// <returns>The same IUnityContainer object that this method was called on.</returns>
IUnityContainer Configure(IUnityContainer container);
}
我希望这可以帮助你。
