Question

我有一个Fluent NHibernate项目，我需要在NHibernate配置上设置一些任意属性。我的第一次尝试是这样的，我从Fluently.Configure()开始，做一些流畅的配置'并调用BuildConfiguration()，然后在该配置上设置一些属性，最后从中构建ISessionFactory。

public static class NHibernateConfigurator
{
    private static readonly Configuration _configuration;
    private static readonly ISessionFactory _sessionFactory;

    static NHibernateConfigurator()
    {
        _configuration = Fluently.Configure()
            .Database(SQLiteConfiguration
                .Standard
                .InMemory()
                .Provider<TestConnectionProvider>()
                .FormatSql())
            .Mappings(m => m.FluentMappings.AddFromAssemblyOf<AcademicTermMapping>())
            .BuildConfiguration();

        _configuration
            .SetProperty(Environment.CollectionTypeFactoryClass, typeof(Net4CollectionTypeFactory).AssemblyQualifiedName)
            .SetProperty(Environment.CurrentSessionContextClass, "thread_static");

        var props = _configuration.Properties;
        if (props.ContainsKey(Environment.ConnectionStringName))
            props.Remove(Environment.ConnectionStringName);

        _sessionFactory = _configuration.BuildSessionFactory();

    }

虽然我最终得到了一个工作会话工厂，但中间的.SetProperty调用似乎被忽略了。（特别是，我知道Environment.CollectionTypeFactoryClass被忽略了，因为我得到了异常。我假设其余部分也被忽略了。）

下一次尝试使用ExposeConfiguration()来设置属性：

    static NHibernateConfigurator()
    {

        _configuration = Fluently.Configure()
            .Database(SQLiteConfiguration
                .Standard
                .InMemory()
                .Provider<TestConnectionProvider>()
                .FormatSql())
            .Mappings(m => m.FluentMappings.AddFromAssemblyOf<AcademicTermMapping>())
            .ExposeConfiguration(ConfigModifier)
            .BuildConfiguration();

        _sessionFactory = _configuration.BuildSessionFactory();

    }

    private static void ConfigModifier(Configuration config)
    {
        config.SetProperty(Environment.CollectionTypeFactoryClass, typeof(Net4CollectionTypeFactory).AssemblyQualifiedName);
        config.SetProperty(Environment.CurrentSessionContextClass, "thread_static");

        var props = config.Properties;
        if (props.ContainsKey(Environment.ConnectionStringName))
            props.Remove(Environment.ConnectionStringName);

    }

但这似乎也不起作用。幸运的是，其中一个属性有一个相应的流畅方法，所以我可以这样做：

_configuration = Fluently.Configure()
    .CollectionTypeFactory<Net4CollectionTypeFactory>()
    // ... etc...

但其余部分没有流利的等价物。我觉得我一定是做错了。

更新

现在变得很奇怪了。按照@Firo的建议，我在BuildConfiguration()之后检查了配置属性。在配置上使用.SetProperty手动设置属性，或使用流畅的.CollectionTypeFactory<Net4CollectionTypeFactory>()在配置上设置相同的属性。但他们最终的顺序不同。所以我尝试在新配置上手动设置属性，然后从那里继续：

    static NHibernateConfigurator()
    {
        var baseConfig = new Configuration();
        baseConfig.SetProperty(Environment.CollectionTypeFactoryClass, typeof(Net4CollectionTypeFactory).AssemblyQualifiedName);

        _configuration = Fluently.Configure(baseConfig)
            .Database(SQLiteConfiguration
                .Standard
                .InMemory()
                .Provider<TestConnectionProvider>()
                .FormatSql())
            .Mappings(m => m.FluentMappings.AddFromAssemblyOf<AcademicTermMapping>())
            .ExposeConfiguration(ConfigModifier)
            .BuildConfiguration();

        _sessionFactory = _configuration.BuildSessionFactory();
    }

    private static void ConfigModifier(Configuration config)
    {
        config.SetProperty(Environment.CurrentSessionContextClass, "thread_static");

        var props = config.Properties;
        if (props.ContainsKey(Environment.ConnectionStringName))
            props.Remove(Environment.ConnectionStringName);
    }

这很有效。不同的方法只是以不同的顺序产生所有相同的属性。以上内容在_configuration.Properties中生成：

[0] = {[use_reflection_optimizer, True]}
[1] = {[collectiontype.factory_class, DataAccess.NHibernate.Net4CollectionTypeFactory, DataAccess.NHibernate, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]}
[2] = {[connection.provider, DataAccess.NHibernate.Tests.TestConnectionProvider, DataAccess.NHibernate.Tests, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]}
[3] = {[connection.driver_class, NHibernate.Driver.SQLite20Driver, NHibernate, Version=3.3.1.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4]}
[4] = {[dialect, NHibernate.Dialect.SQLiteDialect, NHibernate, Version=3.3.1.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4]}
[5] = {[hibernate.dialect, NHibernate.Dialect.SQLiteDialect, NHibernate, Version=3.3.1.4000, Culture=neutral, PublicKeyToken=aa95f207798dfdb4]}
[6] = {[query.substitutions, true=1;false=0]}
[7] = {[connection.release_mode, on_close]}
[8] = {[format_sql, true]}
[9] = {[connection.connection_string, Data Source=:memory:;Version=3;New=True;]}
[10] = {[current_session_context_class, thread_static]}

其他方法按顺序移动collectiontype.factory_class，但顺序无关紧要。
