我在尝试处理消息时将 NServiceBus 4.0.3 与 NHibernate 3.3.1 一起使用时收到错误消息

    INFO  NServiceBus.Unicast.Transport.TransportReceiver [(null)] <(null)> - Failed to process message
Autofac.Core.Registration.ComponentNotRegisteredException: The requested service 'NServiceBus.Impersonation.ExtractIncomingPrincipal' has not been registered. To avoid this exception, either register a component to provide the service, check for service registration using IsRegistered(), or use the ResolveOptional() method to resolve an optional dependency.

我认为我需要实现或注册“ExtractIncomingPrincipal”是相当明显的，但我似乎找不到任何关于如何或是否有我可以使用的默认文档的文档。我不会想到我必须注册任何与 NServiceBus 相关的服务，因为其中许多服务已经在我的 IoC 实现中注册。

根据要求，这是我目前拥有的 EndpointConfig 和支持代码：

[EndpointSLA("00:00:30")]
public class EndpointConfig : IConfigureThisEndpoint, AsA_Server, IWantCustomInitialization {
    public void Init() {
        Configure.With().ObjectBuilderAdapter().UseInMemoryTimeoutPersister().UseInMemoryGatewayPersister().InMemorySagaPersister().InMemorySubscriptionStorage();
   }
}

//public class PrincipalExtractor : ExtractIncomingPrincipal {
//    public IPrincipal GetPrincipal(TransportMessage message) {
//        return Thread.CurrentPrincipal;
//    }
//}

public class ObjectBuilderAdapter : IContainer {
    readonly IDependencyInjector injector;

    public ObjectBuilderAdapter(IDependencyInjectionBuilder dependencyInjectionBuilder) {
        injector = dependencyInjectionBuilder.Create(); //This method does all the common service registrations that I am trying to re-use
        //injector.RegisterType<ExtractIncomingPrincipal, PrincipalExtractor>();
    }

    public void Dispose() {
        injector.Dispose();
    }

    public object Build(Type typeToBuild) {
        return injector.Resolve(typeToBuild);
    }

    public IContainer BuildChildContainer() {
        return new ObjectBuilderAdapter(new DependencyInjectorBuilder());
    }

    public IEnumerable<object> BuildAll(Type typeToBuild) {
        return injector.ResolveAll(typeToBuild);
    }

    public void Configure(Type component, DependencyLifecycle dependencyLifecycle) {
        injector.RegisterType(component);
    }

    public void Configure<T>(Func<T> component, DependencyLifecycle dependencyLifecycle) {
            injector.RegisterType(component);
    }

    public void ConfigureProperty(Type component, string property, object value) {
        if (injector is AutofacDependencyInjector) {
          ((AutofacDependencyInjector)injector).ConfigureProperty(component, property, value);
        } else {
            Debug.WriteLine("Configuring {0} for property {1} but we don't handle this scenario.", component.Name, property);
        }
    }

    public void RegisterSingleton(Type lookupType, object instance) {
        injector.RegisterInstance(lookupType, instance);
    }

    public bool HasComponent(Type componentType) {
        return injector.IsRegistered(componentType);
    }

    public void Release(object instance) { }
}

public static class Extensions {
    public static Configure ObjectBuilderAdapter(this Configure config) {
        ConfigureCommon.With(config, new ObjectBuilderAdapter(new DependencyInjectorBuilder()));
        return config;
    }
}

我删除了类上的 IWantCustomInitialization（我之前尝试过的其他东西留下的）接口实现，我的服务现在处理消息。仍然存在错误（与尝试连接到 Raven 相关[即使我认为我正在使用内存中的所有内容），但它正在处理消息。
