我第一次打电话给我的服务一切正常。之后我收到此错误: "加载Ninject组件ICache \ r \ n时出错\ n此类组件已在内核的组件容器中注册。
我正在调用的控制器在其构造函数中将IKernel作为参数,我的猜测是这就是问题所在。
我应该如何将内核对象传递给我的服务?
我的控制器构造函数:
public MyController(IKernel diContainer)
{
_diContainer = diContainer;
}
我的Global.asax文件的一部分:
var kernel = NinjectWebApi.Kernel;
kernel.Bind<IMyController().To<MyController();
//Set the dependency resolver to use ninject
GlobalConfiguration.Configuration.DependencyResolver = new NinjectDependencyResolver(kernel);
我正在使用Ninject 3.2。
对于我没有将内核传递给服务的其他服务,这种方法可以正常工作。
public class NinjectDependencyScope : IDependencyScope
{
private IResolutionRoot _resolver;
public NinjectDependencyScope(IResolutionRoot resolver)
{
_resolver = resolver;
}
public object GetService(Type serviceType)
{
if (_resolver == null)
{
throw new ObjectDisposedException("this", "This scope has been disposed.");
}
return _resolver.TryGet(serviceType);
}
public IEnumerable<object> GetServices(Type serviceType)
{
if (_resolver == null)
{
throw new ObjectDisposedException("this", "This scope has been disposed.");
}
return _resolver.GetAll(serviceType);
}
public void Dispose()
{
var disposable = _resolver as IDisposable;
disposable?.Dispose();
_resolver = null;
}
}
public class NinjectDependencyResolver : NinjectDependencyScope, IDependencyResolver
{
private readonly IKernel _kernel;
public NinjectDependencyResolver(IKernel kernel) : base(kernel)
{
_kernel = kernel;
}
public IDependencyScope BeginScope()
{
return new NinjectDependencyScope(_kernel.BeginBlock());
}
}

您似乎在NinjectDependenvyResolver Dispose方法中部署了容器。
