"Session is Closed!" - NHibernate
- by Alexis Abril
This is in a web application environment:
An initial request is able to successfully complete, however any additional requests return a "Session is Closed" response from the NHibernate framework. I'm using a HttpModule approach with the following code:
public class MyHttpModule : IHttpModule
{
public void Init(HttpApplication context)
{
context.EndRequest += ApplicationEndRequest;
context.BeginRequest += ApplicationBeginRequest;
}
public void ApplicationBeginRequest(object sender, EventArgs e)
{
CurrentSessionContext.Bind(SessionFactory.Instance.OpenSession());
}
public void ApplicationEndRequest(object sender, EventArgs e)
{
ISession currentSession = CurrentSessionContext.Unbind(
SessionFactory.Instance);
currentSession.Dispose();
}
public void Dispose() { }
}
SessionFactory.Instance is my singleton implementation, using FluentNHibernate to return an ISessionFactory object.
In my repository class, I attempt to use the following syntax:
public class MyObjectRepository : IMyObjectRepository
{
public MyObject GetByID(int id)
{
using (ISession session = SessionFactory.Instance.GetCurrentSession())
return session.Get<MyObject>(id);
}
}
This allows code in the application to be called as such:
IMyObjectRepository repo = new MyObjectRepository();
MyObject obj = repo.GetByID(1);
I have a suspicion my repository code is to blame, but I'm not 100% sure on the actual implementation I should be using.
I found a similar issue on SO here. I too am using WebSessionContext in my implementation, however, no solution was provided other than writing a custom SessionManager. For simple CRUD operations, is a custom session provider required apart from the built in tools(ie WebSessionContext)?
