使用Asp.Net MVC和Web Api配置Ninject

前端之家收集整理的这篇文章主要介绍了使用Asp.Net MVC和Web Api配置Ninject前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我已经设置了我的项目与Ninject IoC。
我的项目有常规的Asp.Net MVC控制器和Web Api控制器。现在,Ninject使用Web Api,但Ninject不工作与常规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,当我尝试与Web Api相同的代码,它的工作原理

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

我的界面保存差异存储库(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类;

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类;

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());
    }
}

Global.asax的Ninject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);
    }
}

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();
}

解决方法

我已经写了一些要点来帮助配置Ninject与MVC和Web Api。只需包括文件

> https://gist.github.com/odytrice/5821087(for MVC)
> https://gist.github.com/odytrice/5842010(适用于WebApi)

要为具体类型添加绑定,只需将它们放在MainModule的Load()方法中。您可以创建尽可能多的模块,以保持绑定的组织。但您还必须将它们添加到Modules属性中返回的数组。

然后添加到Application_Start()方法

> NinjectContainer.RegisterModules(NinjectModules.Modules)(for MVC)
> NinjectHttpContainer.RegisterModules(NinjectHttpModules.Modules)(适用于WebApi)

注意,您可以为MVC和WebApi注册使用相同的NinjectModules.Modules。我只是分开它为了清楚

更新:记住从您的项目中删除NinjectWebCommon.cs,因为它加载和引导一个新的内核在运行时,不幸的是只有为MVC。

更新:你也可以使用

> NinjectContainer.RegisterAssembly()(for MVC)
> NinjectHttpContainer.RegisterAssembly()(用于WebApi)

这将扫描所有模块的当前装配。这样,您可以将模块放置在项目的任何位置,它将被注册
