Ninject从OnApplicationStarted注入​​依赖项

Question

我在我的Global.ascx.cs文件中使用来自OnApplicationStarted的服务。有没有办法从那里依赖注入存储库？

我的代码：

public class MvcApplication : NinjectHttpApplication 
{ 
    //Need to dependency inject this. 
    private IBootStrapService bootService; 

    protected override void OnApplicationStarted() 
    { 
     //Used to set data such as user roles in database on a new app start. 
     bootService.InitDatabase(); 

     base.OnApplicationStarted(); 

     AreaRegistration.RegisterAllAreas(); 
     RegisterGlobalFilters(GlobalFilters.Filters); 
     RegisterRoutes(RouteTable.Routes); 
    } 

    internal class SiteModule : NinjectModule 
    { 
     public override void Load() 
     { 
      //I set my bindings here. 
      Bind<IBootStrapService>().To<BootStrapService>(); 
      Bind<IUserRepository>().To<SqlServerUserRepository>() 
       .WithConstructorArgument("connectionStringName", "MyDb"); 
     } 
    } 
} 

所以我怎么ninject做DI权的内部应用程序启动？正如你所看到的，我在SiteModule类中设置了我的绑定。

您可以覆盖CreateKernel方法，你会注册模块：

protected override IKernel CreateKernel() 
{ 
    return new StandardKernel(
     new INinjectModule[] 
     { 
      new SiteModule() 
     } 
    ); 
} 

这不会自动尽管注入bootService领域。你可以像这样实例化：

protected override void OnApplicationStarted() 
{ 
    base.OnApplicationStarted(); 

    //Used to set data such as user roles in database on a new app start. 
    var bootService = Kernel.Get<IBootStrapService>(); 
    bootService.InitDatabase(); 

    AreaRegistration.RegisterAllAreas(); 
    RegisterGlobalFilters(GlobalFilters.Filters); 
    RegisterRoutes(RouteTable.Routes); 
}
