Question

我有一个使用nhibernate的Web服务。我在repositorry库上有一个单例模式，但每次调用该服务时，它都会创建一个非常昂贵的会话工厂的新实例。我该怎么办？

    #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

我可以通过哪种方式为所有服务创建单个实例？

nhibernate sessionfactory实例不止一次在Web服务上
