사용자 지정 ServiceHostFactory, WAS를 사용할 때 NServiceBus 전송이 NULL입니다.

Question

현재 WCF 서비스에 NServiceBus 3.0을 구현하려고합니다.

사용자 정의 ServiceHostFactory를 사용하여 WAS에서 서비스를 초기화합니다. 우리는 서비스에 액세스 할 수 net.tcp 사용하고 다음 코드를 설정 :

Object reference not set to an instance of an object. 

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

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

     return _container.Kernel; 
    } 
} 

우리가이 오류가 .config

어떤 아이디어가 있습니까?

Answer 1

보통 (적어도 2.6 이상) Windsor Container 구현을 .CastleWindsorBuilder 구성으로 전달합니다. 이를 통해 NSB는 초기화 할 때 올바른 객체 그래프를 생성 할 수 있습니다. 그러면 다음과 같이 보입니다 :

 _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); 

그게 도움이 되나요?
