ASP.NET MVC项目中的Ninject数据注入

Question

我正在开发一个web应用程序，该应用程序在我的ASP.NET MVC5项目中使用Ninject Data注入。我设置了一个从IDdependencyResolver继承的NinjectDependencyResolver:

public class NinjectDependencyResolver : IDependencyResolver
{
private IKernel kernel;
public NinjectDependencyResolver(IKernel kernelParam)
{
kernel = kernelParam;
AddBindings();
}
public object GetService(Type serviceType)
{
return kernel.TryGet(serviceType);
}
public IEnumerable<object> GetServices(Type serviceType)
{
return kernel.GetAll(serviceType);
}
private void AddBindings()
{

// here I have all my bindings set up
kernel.Bind<ProConnect.Domain.Abstract.IMyRepository>().To<MyRepository>();

}
}

这里是NinjectWebCommon类，它在应用程序启动时启动并注册服务：

[assembly: WebActivatorEx.PreApplicationStartMethod(typeof(MyApp.WebUI.App_Start.NinjectWebCommon), "Start")]
[assembly: WebActivatorEx.ApplicationShutdownMethodAttribute(typeof(MyApp.WebUI.App_Start.NinjectWebCommon), "Stop")]
namespace ProConnect.WebUI.App_Start
{
using System;
using System.Web;
using Microsoft.Web.Infrastructure.DynamicModuleHelper;
using Ninject;
using Ninject.Web.Common;
using Ninject.Web.Common.WebHost;
public static class NinjectWebCommon 
{
private static readonly Bootstrapper bootstrapper = new Bootstrapper();
/// <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();
try
{
kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();
RegisterServices(kernel);
return kernel;
}
catch
{
kernel.Dispose();
throw;
}
}
/// <summary>
/// Load your modules or register your services here!
/// </summary>
/// <param name="kernel">The kernel.</param>
private static void RegisterServices(IKernel kernel)
{
// creating the bridge between the NinjectDependencyResolver class and the MVC support for dependency injection.
System.Web.Mvc.DependencyResolver.SetResolver(new
MyApp.WebUI.Infrastructure.NinjectDependencyResolver(kernel));
// maybe I have to add some code here to create the bridge between
// NinjectDependencyResolver class and my standard classes that 
// have nothing to do with MVC????
}
}
}

我使用它将来自域的Repository对象注入到我的MVC控制器中，这一切都非常好。

我遇到的问题是，我想将一些其他存储库对象注入到一个设置类中，该设置类将从数据库中检索一些设置数据。由于我的设置类不是MVC控制器，而只是一个普通的旧类，所以它不知道如何注入数据。

有人能帮我做这个吗？我试着再次设置这样的数据注入，但没有成功：

public class Settings
{

private Domain.Abstract.ISettingRepository settingRepository;
private StandardKernel kernel;

public Settings()
{
this.kernel = new StandardKernel();

// I don't know if this loads a new kernel or the one that is used in the rest of the MVC application
kernel.Load(Assembly.GetExecutingAssembly());

// I tryed re-specifying the bindings but this didn't help
kernel.Bind<Domain.Abstract.ISettingRepository>().To<Domain.Concrete.SettingRepository>();
this.settingRepository = kernel.Get<Domain.Abstract.ISettingRepository>();
}

public void DoSomethigWithSettings(){
this.settingRepository.Settings()......
}
}

好的，多亏了https://stackoverflow.com/a/19585471/11011693

我只是从Application Start 上设置的当前MVC DependencyResolver中获得了要注入到非MVC类中的对象

public class Settings
{
private Domain.Abstract.ISettingRepository settingRepository;
public Settings()
{
// simply get the object you want to inject in a non MVC class 
// from the current MVC DependencyResolver that is set up on Application Start
this.settingRepository = (Domain.Abstract.IAppSettingService)System.Web.Mvc.DependencyResolver.Current.GetService(typeof(Domain.Abstract.IAppSettingService));
}

public void DoSomethigWithSettings(){
this.settingRepository.Settings()......
}
}
