每当我使用 PersitenceSpecification 类来验证具有对值对象的引用的实体时,我都会收到这个奇怪的 ArgumentOutOfRangeException。
public class CatalogItem : DomainEntity
{
internal virtual Manufacturer Manufacturer { get; private
set; }
internal virtual String Name { get; private set; }
protected CatalogItem()
{}
public CatalogItem(String name, String manufacturer)
{
Name = name;
Manufacturer = new Manufacturer(manufacturer);
}
}
public class CatalogItemMapping : ClassMap<CatalogItem>
{
public CatalogItemMapping()
{
Id(catalogItem => catalogItem.Id);
Component<Manufacturer>(category => category.Manufacturer,
m => m.Map(manufacturer =>
manufacturer.Name));
Map(catalogItem => catalogItem.Name);
Map(Reveal.Property<CatalogItem>("Price"));
}
}
[TestFixture]
public class When_verifying_the_class_mapping_of_a_catalog_item
: NHibernateSpecification
{
[Test]
public void Then_a_catalog_object_should_be_persistable()
{
new PersistenceSpecification<CatalogItem>(Session)
.VerifyTheMappings();
}
}
[TestFixture]
public class NHibernateSpecification
: Specification
{
protected ISession Session { get; private set; }
protected override void Establish_context()
{
var configuration = new SQLiteConfiguration()
.InMemory()
.ShowSql()
.ToProperties();
var sessionSource = new SessionSource(configuration, new
RetailerPersistenceModel());
Session = sessionSource.CreateSession();
sessionSource.BuildSchema(Session);
ProvideInitialData(Session);
Session.Flush();
Session.Clear();
}
protected override void Dispose_context()
{
Session.Dispose();
Session = null;
}
protected virtual void ProvideInitialData(ISession session)
{}
}
这是我得到的错误:

很抱歉这篇长文,但这一篇让我忙了几个小时。这可能不是由 FNH 引起的,因为我发现这张 NH 本身的 JIRA 票中提到了类似的内容:
http://forum.hibernate.org/viewtopic.php?p=2395409
我仍然希望我在我的代码中做错了什么:-)。任何想法?
