FluentNhibernate Autofac和Informix数据库

Question

公开会议：

  private static ISession OpenSession(string dbKey)
    {
        try
        {
            var interceptor = new SetSystemPropertiesInterceptor(
                () => DependencyResolver.Current.GetService<IAuthenticationService>()
            );

            ISession session;
            session = NHibernateSessionHelper.GetFactory(dbKey).OpenSession();
            if (session == null)
                throw new InvalidOperationException(string.Format("Call to factory.OpenSession('{0}') returned null.", dbKey));

            session.FlushMode = FlushMode.Never;
            session.BeginTransaction();

            interceptor.SetSession(session);

            return session;
        }
        catch (Exception ex)
        {
            throw new Exception(string.Format("Error on database with key '{0}'", dbKey), ex);
        }
    }

Factory Informix：

        public static ISessionFactory GetFactory(string databaseKey)
    {
        if (!factories.ContainsKey(databaseKey))
        {
            lock (syncObject)
            {
                if (!factories.ContainsKey(databaseKey))
                {
                    ISessionFactory factory = Fluently.Configure()
                                     .Database(
                           IfxSQLIConfiguration
                          .Informix1000
                          .Provider<NHibernate.Connection.DriverConnectionProvider>()
                          .Driver<NHibernate.Driver.IfxDriver>()
                          .Dialect<NHibernate.Dialect.InformixDialect>()
                          .ConnectionString(c => c.FromConnectionStringWithKey(databaseKey))
                          .ShowSql())
                          .Mappings(x => x.FluentMappings.AddFromAssemblyOf<TvLoginMapping>()
                          .Conventions.AddFromAssemblyOf<CustomTypeConvention>()
                          )
                          .BuildSessionFactory();
                    factories.Add(databaseKey, factory);
                }
            }
        }
        return factories[databaseKey];
    }

映射示例：

    public class TvLoginMapping : ClassMap<TvLogin>
{
    public TvLoginMapping()
    {
        this.Table("tvlogin");
        this.Id(X => X.u4976_38748);
        this.Map(X => X.cdlogin);
        this.Map(X => X.nrgrafico);
    }
}

错误：创建SessionFactory时使用了无效或不完整的配置。检查PotentialReasons集合，以及InnerException以获取更多详细信息。

我如何调试？
