我在 C# 4.5 项目中使用 Ninject 作为 IoC 容器。我正在尝试使用 Ninject 注入抽象工厂模式，该模式在 MVC 中运行良好，但在 Web Api 中运行良好。
我安装了以下内容：
Ninject 3.0.1.10
Ninject.Extensions.WCF 3.0.0.5
Ninject.MVC3 3.0.0.6
Ninject.Web.Common 3.0.0.7
SignalR.Ninject
我的工厂类如下所示：
public interface IBusinessEngineFactory
{
T GetBusinessEngine<T>() where T : IBusinessEngine;
}
public interface IBusinessEngine
{
}
public class BusinessEngineFactory : IBusinessEngineFactory
{
private IKernel Kernel { get; set; }
public BusinessEngineFactory(IKernel kernel)
{
Kernel = kernel;
}
T IBusinessEngineFactory.GetBusinessEngine<T>()
{
return Kernel.Get<T>();
}
}
我有标准的 NinjectWebCommon：
公共静态类 NinjectWebCommon { 私有静态只读 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();
kernel.Bind<Func<IKernel>>().ToMethod(ctx => () => new Bootstrapper().Kernel);
kernel.Bind<IHttpModule>().To<HttpApplicationInitializationHttpModule>();
RegisterServices(kernel);
// Install our Ninject-based IDependencyResolver into the Web API config
GlobalConfiguration.Configuration.DependencyResolver = new NinjectResolver(kernel);
return kernel;
}
/// <summary>
/// Load your modules or register your services here!
/// </summary>
/// <param name="kernel">The kernel.</param>
private static void RegisterServices(IKernel kernel)
{
kernel.Bind<IUserIdentity>().To<UserIdentity>();
kernel.Bind<IUnitOfWork>().To<UnitOfWork>();
kernel.Bind<IAlarmEngine>().To<AlarmEngine>();
kernel.Bind<IBusinessEngineFactory>().To<BusinessEngineFactory>();
}
}
这是在控制器中设置的
public class UserController : BaseController
{
public UserController(IBusinessEngineFactory businessEngineFactory, IUnitOfWork unitOfWork, UserIdentity userIdentity)
: base(businessEngineFactory, unitOfWork, userIdentity)
{
}
...
public ActionResult Edit(int id = 0)
{
...
var x = BusinessEngineFactory.GetBusinessEngine<IAlarmEngine>();
x.ProcessAlarmEventUpdate("test");
return View(x);
}
}
哪个工作正常。我遇到问题的地方是 WebAPIController 中的相同代码：
public class AlarmWebApiController : ApiController
{
public IBusinessEngineFactory BusinessEngineFactory { get; set; }
public IUnitOfWork UnitOfWork {get; set;}
public IUserIdentity UserIdentity { get; set; }
public AlarmWebApiController(IBusinessEngineFactory businessEngineFactory, IUnitOfWork unitOfWork, IUserIdentity userIdentity)
{
if (businessEngineFactory == null) throw new NullReferenceException("businessEngineFactory");
BusinessEngineFactory = businessEngineFactory;
if (unitOfWork == null) throw new NullReferenceException("unitOfWork");
UnitOfWork = unitOfWork;
if (userIdentity == null) throw new NullReferenceException("userIdentity");
UserIdentity = userIdentity;
}
}
当我运行它时，MVC 控制器处理正常，但 Web API 函数没有，并且我得到了在调用 webapi 的构造函数中的任何代码之前发生的模糊错误消息。
“加载 Ninject 组件 ICache 时出错
内核的组件容器中没有注册组件”
我认为问题在于 MVC 了解内核，但因为 WebAPI 使用它：
GlobalConfiguration.Configuration.DependencyResolver = new NinjectResolver(kernel);
所以它不知道内核。用于创建业务引擎的代码存在于与主 MVC、Web API 和 ninject 创建不同的项目中，如果可以的话，我不希望依赖 System.Web.Http（对于 GlobalConfiguration.Configuration.DependencyResolver 对象）帮助它。有什么方法可以让它同时在 MVC 和 WebAPI 上工作？
