How can I implement NHibernate session per request without a dependency on NHibernate?
- by Ben
I've raised this question before but am still struggling to find an example that I can get my head around (please don't just tell me to look at the S#arp Architecture project without at least some directions).
So far I have achieved near persistance ignorance in my web project. My repository classes (in my data project) take an ISession in the constructor:
public class ProductRepository : IProductRepository
{
private ISession _session;
public ProductRepository(ISession session) {
_session = session;
}
In my global.asax I expose the current session and am creating and disposing session on beginrequest and endrequest (this is where I have the dependency on NHibernate):
public static ISessionFactory SessionFactory = CreateSessionFactory();
private static ISessionFactory CreateSessionFactory() {
return new Configuration()
.Configure()
.BuildSessionFactory();
}
protected MvcApplication() {
BeginRequest += delegate {
CurrentSessionContext.Bind(SessionFactory.OpenSession());
};
EndRequest += delegate {
CurrentSessionContext.Unbind(SessionFactory).Dispose();
};
}
And finally my StructureMap registry:
public AppRegistry() {
For<ISession>().TheDefault
.Is.ConstructedBy(x => MvcApplication.SessionFactory.GetCurrentSession());
For<IProductRepository>().Use<ProductRepository>();
}
It would seem I need my own generic implementations of ISession and ISessionFactory that I can use in my web project and inject into my repositories?
I'm a little stuck so any help would be appreciated.
Thanks,
Ben
