我是 fluent hibernate 的新手，在尝试创建过滤器时遇到异常。

我发现这个语法用 Fluent Nhibernate 定义 NHibernate 过滤器？

它解释了如何创建一个流畅的过滤器，直到我尝试运行我的应用程序。我得到一个例外（见下文）。我的代码与上面发布的链接相同。这是导致异常的代码。如果我只为映射添加 1 个程序集，例如 HotelMap，问题就消失了，当我添加 2 个或更多时，我得到了异常。

任何想法将不胜感激。

private static ISessionFactory BuildSessionFactory()
    {
        var connectionString = DatabaseConnectionStringsFactory.GetConnectionString(DatabaseConnectionStringsFactory.DEFAULT);
        try
        {
            var session = Fluently.Configure()
                .Database(
                    MsSqlConfiguration.MsSql2008.
                        ConnectionString(connectionString).
                        AdoNetBatchSize(50)
                )
                .Mappings(m => m.FluentMappings.Add(typeof(CultureFilter.PonyConditionFilter)))
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<AgentMap>())
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<HotelMap>())
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<RoomMap>())
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<SeasonMap>())
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<BookingsMap>())
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<CustomerMap>())
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<PriceMap>())
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<GroupRoomsMap>())
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<PermissionsToBooking>())
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<Address>())
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<Owner>())
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<BookingCancelledBy>())
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<RelatedBookings>())
                .ExposeConfiguration(c =>c.SetProperty("current_session_context_class", "thread_static"))
                .BuildSessionFactory();

            session.OpenSession().EnableFilter("PonyConditionFilter").SetParameter("condition", false);
            return session;

        }
        catch (Exception e)
        {
            throw e;
        }
    }

这是例外

如果所有映射都位于同一个程序集中，则只需为每个程序集添加一个 AddFromAssembly 行。

Fluent NHibernate 将扫描整个程序集以查找您的映射并添加它们。

试试这个：

var session = Fluently.Configure()
                .Database(
                    MsSqlConfiguration.MsSql2008.
                        ConnectionString(connectionString).
                        AdoNetBatchSize(50)
                )
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<AgentMap>())
                .ExposeConfiguration(c =>c.SetProperty("current_session_context_class", "thread_static"))
                .BuildSessionFactory();
