How to dispose NHibernate ISession in an ASP.NET MVC App
- by Joe Young
I have NHibernate hooked up in my asp.net mvc app.
Everything works fine, if I DON'T dispose the ISession. I have read however that you should dispose, but when I do, I get random "Session is closed" exceptions.
I am injecting the ISession into my other objects with Windsor.
Here is my current NHModule:
public class NHibernateHttpModule : IHttpModule
{
public void Init(HttpApplication context)
{
context.BeginRequest += context_BeginRequest;
context.EndRequest += context_EndRequest;
}
static void context_EndRequest(object sender, EventArgs e)
{
CurrentSessionContext.Unbind(MvcApplication.SessionFactory);
}
static void context_BeginRequest(object sender, EventArgs e)
{
CurrentSessionContext.Bind(MvcApplication.SessionFactory.OpenSession());
}
public void Dispose()
{
// do nothing
}
}
Registering the ISession:
container
.Register(Component.For<ISession>()
.UsingFactoryMethod(() => MvcApplication.SessionFactory.GetCurrentSession()).LifeStyle.Transient);
The error happens when I tack the Dispose on the unbind in the module. Since I keep getting the session is closed error I assume this is not the correct way to do this, so what is the correct way?
Thanks,
Joe
