Question

我正在尝试使用Bootstrapper with Ninject。我已经安装Ninject.MVC3来从nuget初始化我的Ninject容器，我已经创建了一个这样的测试模块：

public class TestNinjectModule : NinjectModule
{
    public override void Load()
    {
        Bind<DBEntities>().ToSelf().InRequestScope();
        Bind(typeof(IGenericRepository<>))
              .To(typeof(GenericRepository<>)).InRequestScope();
        Bind<ISystemRepository>().To<SystemRepository>().InRequestScope();
        Bind<IUnitOfWork>().To<UnitOfWork>();
    }
}

我还在Start()

中加入了Global.asax.cs来电

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        WebApiConfig.Register(GlobalConfiguration.Configuration);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);

        Bootstrapper.With.Ninject().Start();
        Bootstrapper.With.AutoMapper().Start();
    }
}

但是当调用具有依赖关系的控制器时，我仍然从Ninject获得ActivationException，并且未调用我的TestNinjectModule.Load()方法。我该如何解决？

异常消息：

激活IUnitOfWork时出错   没有匹配的绑定可用，并且该类型不可自绑定。   激活路径：     2）将依赖项IUnitOfWork注入到类型为＆gt;的构造函数的参数unitOfWork中。 TreasurySystemController     1）对SystemController的请求

建议：     1）确保已为IUnitOfWork定义了绑定。     2）如果在模块中定义了绑定，请确保已将模块加载到＆gt;中。内核。     3）确保您没有意外创建多个内核。     4）如果使用构造函数参数，请确保参数名称与＆gt;构造函数参数名称匹配。     5）如果您使用自动模块加载，请确保搜索路径和过滤器正确无误。

我找到了解决方案。通过将NinjectWebCommon的实施更改为：

public static class NinjectWebCommon 
{
    private static readonly Bootstrapper bootstrapper = new Bootstrapper();
    public static IKernel Kernel { get; private set; } // Expose the kernel through a property

    /// <summary>
    /// Starts the application
    /// </summary>
    public static void Start() 
    {
        DynamicModuleUtility.RegisterModule(typeof(OnePerRequestHttpModule));
        DynamicModuleUtility.RegisterModule(typeof(NinjectHttpModule));
        bootstrapper.Initialize(CreateKernel);
    }

    /// <summary>
    /// Stops the application.
    /// </summary>
    public static void Stop()
    {
        bootstrapper.ShutDown();
    }

    /// <summary>
    /// Creates the kernel that will manage your application.
    /// </summary>
    /// <returns>The created kernel.</returns>
    private static IKernel CreateKernel()
    {
        var kernel = new StandardKernel();
        kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
        kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();

        return Kernel = kernel;
    }
}

然后在Global.asax.cs：

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        WebApiConfig.Register(GlobalConfiguration.Configuration);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);

        Bootstrapper.With.AutoMapper().Start();
        Bootstrapper.With.Ninject()
            .WithContainer(NinjectWebCommon.Kernel) // Use the kernel inside NinjectWebCommon instead of creating a new one
            .Start();
    }
}

然后，从NinjectModule派生的所有类都将调用Load()方法。

Bootstrapper不加载我的NinjectModules
