the first problem is that you should not call new Configuration in
begin request. in it's simplest form the global asax can look like
this
class Global : HttpApplicaiton
{
public static ISessionFactory factory {get; private set;}
public Global()
{
BeginRequest += (o, e) =>
CurrentSessionContext.Bind(factory.OpenSession());
EndRequest += (o, e) =>
CurrentSessionContext.Unbind(factory).Dispose();
}
protected void Application_Start(object sender, EventArgs e)
{
factory = new
Configuration().Configure().BuildSessionFactory();
}
protected void Application_End(object sender, EventArgs e)
{
factory.Dispose();
}
}
create an action filter to manage the transaction
class TransactionFilter : Filter
{
public bool BeforeAction(Context context...)
{
Global.factory.GetCurrentSession().BeginTransaction();
}
public void AfterAction(Context context...)
{
using(var tx = Global.factory.GetCurrentSession()Transaction)
{
if(context.LastError == null)
{
tx.Commit();
}
else
{
tx.Rollback();
}
}
}
}
then your controllers can look like this
class MyController : Controller
{
[TransactionFilter]
public ActionResult Index(long id);
{
var data = Global.factory.GetCurrentSession().Get<Entity>(id);
return ViewResult{Model = data};
}
}
if you're using an IoC container than you can remove of a public
static property on global for the factory. The key is that Session
Factory is a singleton. from this point NH has exhaustive error
checking to ensure the configuration and mappings are correct. follow
the advice of the exception message and you should be able to solve
most problems.
