Fluent Nhibernate - asp.net-mvc

Question

I am trying to use Fluent NHibernate with ASP.NET MVC 3 and I cannot seem to find a tutorial that explains how to get it all configured with ASP.NET MVC. I mainly am wondering where to put the ISession building function and how to call it when I need it. I see so many different implementations but none of them specify where they put this code. So if anyone can explain how to get it all configured to work with MVC 3 or where a very detailed tutorial is, that would be greatly appreciated.

Answer 1

You can have a look at S#arp Architecture.
It's a pretty solid architectural framework to work with ASP.NET MVC & NHibernate. They have a decent documentation and there's some sample projects to look at.

If you are not using dependency injection you can try something like this
public class MvcApplication : System.Web.HttpApplication
{
public static ISession CurrentSession
{
get { return (ISession)HttpContext.Current.Items["current.session"]; }
set { HttpContext.Current.Items["current.session"] = value; }
}
private static ISessionFactory _session_factory;
private static object _session_factory_lock = new object();
protected static ISessionFactory CreateSessionFactory()
{
if (_session_factory != null) return _session_factory;
if (ConfigurationManager.ConnectionStrings["DbConnection"] != null)
{
var conn = ConfigurationManager.ConnectionStrings["DbConnection"];
SqlServerSessionFactoryBuilder fb = new SqlServerSessionFactoryBuilder(conn.ConnectionString);
_session_factory = fb.GetSessionFactory();
return _session_factory;
}
throw new Exception("Cannot build session factory, connection string is not defined.");
}
public MvcApplication()
{
_session_factory = CreateSessionFactory();
BeginRequest += delegate
{
try
{
CurrentSession = _session_factory.OpenSession();
}
catch (FluentConfigurationException ex)
{
logger.FatalException(string.Format("Error configuring the database {0}", ex.Message), ex);
}
};
EndRequest += delegate
{
if (CurrentSession != null)
{
if (CurrentSession.Transaction != null && CurrentSession.Transaction.IsActive)
{
logger.Error("Rolling back uncommited transaction");
CurrentSession.Transaction.Rollback();
}
else
{
CurrentSession.Flush();
}
CurrentSession.Close();
}
};
Error += delegate
{
var error = this.Server.GetLastError();
logger.ErrorException(string.Format("Unhandled error : {0}", error.Message), error);
};
}
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterRoutes(RouteTable.Routes);
}
}
