nhibernate sessionfactory instance more than once on web service
- by Manuel
Hello, i have a web service that use nhibernate. I have a singleton pattern on the repositorry library but on each call the service, it creates a new instance of the session factory wich is very expensive. What can i do?
region Atributos
/// <summary>
/// Session
/// </summary>
private ISession miSession;
/// <summary>
/// Session Factory
/// </summary>
private ISessionFactory miSessionFactory;
private Configuration miConfiguration = new Configuration();
private static readonly ILog log = LogManager.GetLogger(typeof(NHibernatePersistencia).Name);
private static IRepositorio Repositorio;
#endregion
#region Constructor
private NHibernatePersistencia()
{
//miConfiguration.Configure("hibernate.cfg.xml");
try
{
miConfiguration.Configure();
this.miSessionFactory = miConfiguration.BuildSessionFactory();
this.miSession = this.SessionFactory.OpenSession();
log.Debug("Se carga NHibernate");
}
catch (Exception ex)
{
log.Error("No se pudo cargar Nhibernate " + ex.Message);
throw ex;
}
}
public static IRepositorio Instancia
{
get
{
if (Repositorio == null)
{
Repositorio = new NHibernatePersistencia();
}
return Repositorio;
}
}
#endregion
#region Propiedades
/// <summary>
/// Sesion de NHibernate
/// </summary>
public ISession Session
{
get { return miSession.SessionFactory.GetCurrentSession(); }
}
/// <summary>
/// Sesion de NHibernate
/// </summary>
public ISessionFactory SessionFactory
{
get { return this.miSessionFactory; }
}
#endregion
In wich way can i create a single instance for all services?
