The problem I'd like to solve is sharing an ISessionProvider between IXyzRepositories (where ISess开发者_如何学JAVAionProvider holds the current NHibernate ISession).
I'm tweaking the "Setting up session per presenter" recipe from NHibernate 3 Cookbook, and would like to keep StructureMap (brownfield project).
I think you would have to create a custom Lifecyle to do that, although I am not sure what exactly you are trying to accomplish...
To create a custom Lifecycle, you just have to implement the ILifecycle interface and the use it in your registration. Here is an example you can look at: http://blog.mikeobrien.net/2010/01/creating-structuremap-lifecycle-for-wcf.html.
In a web application I use Singleton for the sessionFactory and HybridHttpOrThreadLocalScoped for the session: This is my structuremap registry:
public class NhibernateRegistry: Registry
{
public NhibernateRegistry()
{
For<ISessionFactory>()
.Singleton()
.Use(new NHibernateSessionFactory(connectionString).SessionFactory);
For<ISession>()
.HybridHttpOrThreadLocalScoped()
.Use(o => o.GetInstance<ISessionFactory>().CurrentSession);
}
}
My NHibernateSessionFactory is similar to SessionProvider class used in the book. Everything is disposed at the end of the request (web app):
protected void Application_EndRequest(object sender, EventArgs e)
{
ObjectFactory.ReleaseAndDisposeAllHttpScopedObjects();
}
I use a generic repository:
public class GenericRepository<T> : IGenericRepository<T> where T : class
{
private readonly ISession _session;
public GenericRepository(ISession session)
{
_session = session;
}
public T Load(Guid Code)
{
return (_session.Load<T>(Code));
}
}
but you can easily change it with your own implementation. I register the repository here:
public class RepositoriesRegistry : Registry
{
public RepositoriesRegistry()
{
For <Data.IRepository<Domain.Reminder, Guid>>()
.HybridHttpOrThreadLocalScoped()
.Use<Data.NH.Repository<Domain.Reminder, Guid>>();
}
}
