I've been trying for ages to figure this our. when i try to bind my class with an interceptor i'm getting the following exception on the line
Kernel.Bind<MyClass>().ToSelf().Intercept().With<ILoggerAspect>();
Error loading Ninject component IAdviceFactory. No such component has been registered in the kernel's component container
I've tried with and without LoadExtensions, With about with using a Module to set up my bindings and my last attempt looks like this
internal class AppConfiguration
{
internal AppConfiguration( )
{
var settings = new NinjectSettings() { LoadExtensions = false };
Kernel = new StandardKernel(settings);
Load();
}
internal StandardKernel Kernel { get; set; }
public static AppConfiguration Instance
{
get { return _instance ?? (_instance = new AppConfiguration()); }
}
private static AppConfiguration _instance;
private void Load()
{
Kernel.Bind<ILoggerAspect>().To<Log4NetAspect>().InSingletonScope();
Kernel.Bind<MyClass>().ToSelf().Intercept().With<ILoggerAspect>();
}
internal static StandardKernel Resolver()
{
return Instance.Kernel;
}
}
My Logger Attribute looks like this
public class LogAttribute : InterceptAttribute
{
public override IInterceptor CreateInterceptor(IProxyRequest request)
{
return request.Context.Kernel.Get<ILoggerAspect>();
}
}
And my interceptor like this
public class Log4NetAspect : SimpleInterceptor, ILoggerAspect
{
protected override void BeforeInvoke(IInvocation invocation)
{
Debug.WriteLine("Running " + invocation.ReturnValue);
base.BeforeInvoke(invocation);
}
public new void Intercept(IInvocation invocation)
{
try
{
base.Intercept(invocation);
}
catch (Exception e)
{
Debug.WriteLine("Exception: " + e.Message);
}
}
protected override void AfterInvoke(IInvocation invocation)
{
Debug.WriteLine("After Method");
base.AfterInvoke(invocation);
}
}
Most likely you didn't deploy Ninject.Extensions.Interception.DynamicProxy
or Ninject.Extensions.Interception.Linfu
alongside your application [and Ninject.Extensions.Interception
]. You have to pick exactly one of them.
With the code as you have it right now (LoadExtensions=false
) it will fail to pick up the specific interception library - you should remove that and the normal extensions loading should wire the extension into the Kernel on creation for the interception bits to pick it up.
