have a WCF service instance activated through a ServiceBehavior that
configures Castle Windsor as IoC container as uses it to resolve the
service implementation (and so all its dependency graph).
Windsor container is configured with NHibernateFacility set up through
configuration and these facilities set up in code:
TransactionFacility, TypedFactoryFacility.
The trouble here is that the TransactionInterceptor does not get
invoked around the call to MyTransactionalMethod() made in the body of
Operation() method. If I set the 'Transaction' attribute on the
Operation() method the interceptor gets invoked as expected. It seems
to me as the proxy is created against service interface only.
Moreover, stepping through TransactionFacility code can be noted that
the interceptor is correctly added to the component model during model
inspection. As a note, attached to this service I have also a custom
interceptor registered as last, but I think it is not influent at all.
I'm rather new to Castle Windsor and probably I'm missing something
about DynamicProxy and interceptors implementation, so I ask here for
an explanation to this behavior and how I can obtain the one I need.
Below a skeleton of the components involved. For brevity I omit
explaining the reason why I cannot annotate Operation() with
'Transaction', but it is due to the fact that I need to "do stuff"
after the transaction is closed.
Thanks in advance, Andrea
// Code skeleton
[ServiceContract]
public interface IService {
[OperationContract]
void Operation();
}
[Transactional]
public class ServiceImpl : IService {
public void Operation() {
MyTransactionalMethod();
// do stuff out of transaction scope
}
[Transaction(TransactionMode.Requires)]
protected virtual void MyTransactionalMethod(){
// stuff that deals with Dao(s).
}
}
