エンティティフレームワーク6で.NET MVC 5アプリケーションを開発中です。 私は既にデータベースを作成しています。単純なViewModelを作成し、それをHomeControllerで使用しました。これは私にHomeControllerあるAutoMapper使用時にIConfigurationProviderをアクティブ化できません
Error activating IConfigurationProvider No matching bindings are available, and the type is not self-bindable. Activation path: 3) Injection of dependency IConfigurationProvider into parameter configurationProvider of constructor of type Mapper 2) Injection of dependency IMapper into parameter mapper of constructor of type HomeController 1) Request for HomeController
Suggestions: 1) Ensure that you have defined a binding for IConfigurationProvider. 2) If the binding was defined in a module, ensure that the module has been loaded into the kernel. 3) Ensure you have not accidentally created more than one kernel. 4) If you are using constructor arguments, ensure that the parameter name matches the constructors parameter name. 5) If you are using automatic module loading, ensure the search path and filters are correct.
：
：public ActionResult Index()
{
var ads = this.adService
.GetAll()
.ToList()
.Select(x => this.mapper.Map<AdViewModel>(x));
var viewModel = new MainViewModel()
{
Ads = ads,
};
return View(viewModel);
//return View();
}
これは私のAutoMapperConfigurationされるコントローラでのデータベースモデルとViewModelには、私はこのエラーを取得します
public class AutoMapperConfig
{
public static IMapperConfigurationExpression Configuration { get; private set; }
public void Execute(Assembly assembly)
{
Mapper.Initialize(
cfg =>
{
var types = assembly.GetExportedTypes();
LoadStandardMappings(types, cfg);
LoadCustomMappings(types, cfg);
Configuration = cfg;
});
}
private static void LoadStandardMappings(IEnumerable<Type> types, IMapperConfigurationExpression mapperConfiguration)
{
var maps = (from t in types
from i in t.GetInterfaces()
where i.IsGenericType && i.GetGenericTypeDefinition() == typeof(IMapFrom<>) &&
!t.IsAbstract &&
!t.IsInterface
select new
{
Source = i.GetGenericArguments()[0],
Destination = t
}).ToArray();
foreach (var map in maps)
{
mapperConfiguration.CreateMap(map.Source, map.Destination);
mapperConfiguration.CreateMap(map.Destination, map.Source);
}
}
private static void LoadCustomMappings(IEnumerable<Type> types, IMapperConfigurationExpression mapperConfiguration)
{
var maps = (from t in types
from i in t.GetInterfaces()
where typeof(IHaveCustomMappings).IsAssignableFrom(t) &&
!t.IsAbstract &&
!t.IsInterface
select (IHaveCustomMappings)Activator.CreateInstance(t)).ToArray();
foreach (var map in maps)
{
map.CreateMappings(mapperConfiguration);
}
}
}
}
NinjectConfig：
private static void RegisterServices(IKernel kernel)
{
kernel.Bind(x =>
{
x.FromThisAssembly()
.SelectAllClasses()
.BindDefaultInterface();
});
kernel.Bind(x =>
{
x.FromAssemblyContaining(typeof(IService))
.SelectAllClasses()
.BindDefaultInterface();
});
kernel.Bind(typeof(IEfRepository<>)).To(typeof(EfRepository<>));
kernel.Bind(typeof(DbContext), typeof(MsSqlDbContext)).To<MsSqlDbContext>().InRequestScope();
kernel.Bind<ISaveContext>().To<SaveContext>();
kernel.Bind<IMapper>().To<Mapper>();
}
とのGlobal.asax：
protected void Application_Start()
{
Database.SetInitializer(new MigrateDatabaseToLatestVersion<MsSqlDbContext, Configuration>());
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
var mapper = new AutoMapperConfig();
mapper.Execute(Assembly.GetExecutingAssembly());
}
私はこのエラーを解決するためのアイデアを見て楽しみにしています、そしてどのように注入するためにこのIConfigurationProvider？
