NServiceBus Transport ist NULL, wenn ein benutzerdefiniertes ServiceHostFactory verwendet wird, WAS

Question

Wir versuchen derzeit, NServiceBus 3.0 in unseren WCF-Diensten zu implementieren.

Wir verwenden eine benutzerdefinierte ServiceHostFactory, um unsere Dienste in WAS zu initialisieren. Wir verwenden net.tcp auf die Dienste zuzugreifen und den folgenden Code, um es einzurichten:

public class DoServiceServiceHostFactory : DefaultServiceHostFactory 
{ 
    private static IWindsorContainer _container; 

    public DoServiceServiceHostFactory() 
     : base(CreateKernel()) 
    { 
    } 

    private static IKernel CreateKernel() 
    { 
     _container = new WindsorContainer(); 

     IocModules.Configure(_container, new WcfConfigurationModule()); 
     IocModules.Configure(_container, new WcfAdapterModule()); 
     IocModules.Configure(_container, new ManagerModule()); 
     IocModules.Configure(_container, new FactoryModule()); 

     IBus bus = Configure.WithWeb() 
       .DefineEndpointName("OurProjectPublisher") 
       .DefiningEventsAs(t => t.Namespace != null && t.Namespace.StartsWith("MY.Bus.Contracts.Events")) 
       .CastleWindsorBuilder() 
       .Log4Net() 
       .XmlSerializer() 
       .MsmqTransport() 
       .UnicastBus() 
       .CreateBus() 
       .Start(() => Configure.Instance.ForInstallationOn<NServiceBus.Installation.Environments.Windows>().Install()); 
     //_container.Register(Component.For<IBus>().Instance(bus).LifeStyle.Singleton); 

     WindsorServiceLocator serviceLocator = new WindsorServiceLocator(_container); 
     ServiceLocator.SetLocatorProvider(() => serviceLocator); 

     return _container.Kernel; 
    } 
} 

wenn wir den Service rufen erhalten wir diesen Fehler:

diese Irgendwelche Ideen über?

Answer 1

Normalerweise (mindestens in 2.6) würden Sie die Implementierung Ihres Windsor Containers an die .CastleWindsorBuilder Konfiguration übergeben. Dadurch kann NSB beim Initialisieren das richtige Objektdiagramm erstellen. So würde es wie folgt aussehen:

 _container = new WindsorContainer(); 

     IocModules.Configure(_container, new WcfConfigurationModule()); 
     IocModules.Configure(_container, new WcfAdapterModule()); 
     IocModules.Configure(_container, new ManagerModule()); 
     IocModules.Configure(_container, new FactoryModule()); 

     IBus bus = Configure.WithWeb() 
       .DefineEndpointName("OurProjectPublisher") 
       .DefiningEventsAs(t => t.Namespace != null && t.Namespace.StartsWith("MY.Bus.Contracts.Events")) 
       .CastleWindsorBuilder(_container) // added here 
       .Log4Net() 
       .XmlSerializer() 
       .MsmqTransport() 
       .UnicastBus() 
       .CreateBus() 
       .Start(() => Configure.Instance.ForInstallationOn<NServiceBus.Installation.Environments.Windows>().Install()); 
     //_container.Register(Component.For<IBus>().Instance(bus).LifeStyle.Singleton);
