I inject a session as a ctor dependency like this
class Service
{
private readonly ISession session;
public Service(ISession session)
{
this.session = session;
}
public void DoWork(int id)
{
var entity = session.Load<Entity>(id);
session.Delete(entity)
}
}
class SessionResolver : ISubDependencyResolver
{
private readonly ISessionFactory factory;
public SessionResolver(ISessionFactory factory)
{
this.factory = factory;
}
public object Resolve(...)
{
return new SessionAdapter(factory);
}
public bool CanResolve(...)
{
return typeof(ISession).IsAssignableFrom
(dependency.TargetType);
}
}
class SessionAdapter : ISession
{
private readonly ISessionFactory factory;
public SessionAdapter(ISessionFactory factory)
{
this.factory = factory;
}
private ISession session { get { return factory.GetCurrentSession
(); } }
private T Load<T>(object id)
{
return session.Load<T>(id);
}
private Delete(object entity)
{
return session.Delete(entity);
}
//the rest of the ISession members...
}
