Question

我在使用NServiceBus 4.0.3和NHibernate 3.3.1时尝试处理消息时收到错误

    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，但我似乎无法找到有关如何或是否存在我可以使用的默认文档的任何文档。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IWantCustomInitialization（从我之前尝试的其他东西遗留下来的）接口实现，我的服务现在处理消息。还有错误（与尝试连接到Raven有关[尽管我以为我正在使用内存中的所有内容]，但它正在处理消息。

NServiceBus无法处理消息：请求的服务'NServiceBus.Impersonation.ExtractIncomingPrincipal'尚未注册
