我已经设置了我的项目Ninject IoC
。
我的项目有常规Asp.Net MVC
控制器和Web Api
控制器。现在,Ninject
适用于Web Api
但Ninject
不适用于常规Asp.MVC
控制器。
我的常规 MVC 控制器实现;
public class GalleryController : BaseController
{
public GalleryController(IUow uow)
{
Uow = uow;
}
........
}
与常规控制器一起使用时出错
An error occurred when trying to create a controller of type 'Web.Controllers.HomeController'. Make sure that the controller has a parameterless public constructor.]
但是,当我使用Web Api尝试相同的代码时,它可以工作
public class GalleryController : BaseApiController
{
public GalleryController(IUow uow)
{
Uow = uow;
}
......
}
我的界面包含不同的存储库(工厂模式)
public interface IUow
{
// Save pending changes to the data store.
void Commit();
//Repositoryries
IRepository<Gallery> Gallery { get; }
IMenuRepository Menus { get; }
}
NinjectDependencyScope
班级;
public class NinjectDependencyScope : IDependencyScope
{
private IResolutionRoot resolver;
internal NinjectDependencyScope(IResolutionRoot resolver)
{
Contract.Assert(resolver != null);
this.resolver = resolver;
}
public void Dispose()
{
var disposable = resolver as IDisposable;
if (disposable != null)
disposable.Dispose();
resolver = null;
}
public object GetService(Type serviceType)
{
if (resolver == null)
throw new ObjectDisposedException("this", "This scope has already been disposed");
return resolver.TryGet(serviceType);
}
public IEnumerable<object> GetServices(Type serviceType)
{
if (resolver == null)
throw new ObjectDisposedException("this", "This scope has already been disposed");
return resolver.GetAll(serviceType);
}
}
NinjectDependencyResolver
班级;
public class NinjectDependencyResolver : NinjectDependencyScope, IDependencyResolver
{
private IKernel kernel;
public NinjectDependencyResolver(IKernel kernel)
: base(kernel)
{
this.kernel = kernel;
}
public IDependencyScope BeginScope()
{
return new NinjectDependencyScope(kernel.BeginBlock());
}
}
Ninject
Global.asax 的配置;
public class IocConfig
{
public static void RegisterIoc(HttpConfiguration config)
{
var kernel = new StandardKernel(); // Ninject IoC
//kernel.Load(Assembly.GetExecutingAssembly()); //only required for asp.net mvc (not for webapi)
// These registrations are "per instance request".
// See http://blog.bobcravens.com/2010/03/ninject-life-cycle-management-or-scoping/
kernel.Bind<RepositoryFactories>().To<RepositoryFactories>()
.InSingletonScope();
kernel.Bind<IRepositoryProvider>().To<RepositoryProvider>();
kernel.Bind<IUow>().To<Uow>();
// Tell WebApi how to use our Ninject IoC
config.DependencyResolver = new NinjectDependencyResolver(kernel);
}
}
全球.asax
protected void Application_Start()
{
// Tell WebApi to use our custom Ioc (Ninject)
IocConfig.RegisterIoc(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
GlobalConfig.CustomizeConfig(GlobalConfiguration.Configuration);
AreaRegistration.RegisterAllAreas();
}
