使用Asp.Net配置Ninject MVC& Web Api [英] Configuring Ninject with Asp.Net MVC & Web Api

问题描述

我已经使用 Ninject IoC 设置我的项目。

我的项目具有常规的 Asp.Net MVC 控制器和 Web Api 控制器。现在， Ninject 使用 Web Api 但 Ninject t定期使用 Asp.MVC 控制器。


我的常规MVC控制器实现;

i have setup my project with Ninject IoC.
My project has regular Asp.Net MVC controllers and Web Api controllers. Now, Ninject works with Web Api but Ninject doesn't work with regular Asp.MVC controllers.
My regular MVC controller implementation;

public class GalleryController : BaseController
{
    public GalleryController(IUow uow)
    {
        Uow = uow;
    }
    ........
}

使用常规控制器时出错

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，当我尝试相同的代码 Web Api

However, when i try the same code with Web Api, it works

public class GalleryController : BaseApiController
{
    public GalleryController(IUow uow)
    {
        Uow = uow;
    }
    ......
}

我的存储不同存储库（工厂模式）的接口

my interface which holds difference repositories (the factory pattern)

public interface IUow
{
    // Save pending changes to the data store.
    void Commit();

    //Repositoryries
    IRepository<Gallery> Gallery { get; }
    IMenuRepository Menus { get; }
}

NinjectDependencyScope class ;

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 class;

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 配置为Global.asax;

Ninject configuration for Global.asax;

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);
    }
}

Global.asax

Global.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();
}

推荐答案

搜索很多，原来我们不能用网络api和普通的mvc使用Ninject。我的意思是，我们必须分别配置存储库。

After searching a lot, it turns out there we can't use Ninject with web api and regular mvc. I mean, we have to configure the Repositories separately.

然后，我发现一篇很好的文章，解释了如何使用Ninject与asp.net mvc& web api： http：/ /www.codeproject.com/Articles/412383/Dependency-Injection-in-asp-net-mvc4-and-webapi-us

I then found a nice article which explains how you can use Ninject with asp.net mvc & web api: http://www.codeproject.com/Articles/412383/Dependency-Injection-in-asp-net-mvc4-and-webapi-us

而现在，我没有得到错误，它的工作：D

And now, I don't get the error and it's working :D

更新1：

另请尝试使用.NET Framework 4.5在MVC 4 Web API中编写依赖注入的简单实现
