在使用FluentNHibernate的SaveOrUpdate上什么也不会发生

Question

在FluentNHibernate中使用SaveOrUpdate方法更新实体时不会发生任何操作。Flush确实可以工作，但由于现有的存储库基础设施，我想使用SaveOrUpdate。可能的问题是什么？

配置：

sessionFactory = Fluently.Configure()
    .Database(MsSqlConfiguration
        .MsSql2005
            .ConnectionString(c => c.FromConnectionStringWithKey("repository")))
        .Mappings(m => m.FluentMappings
            .AddFromAssemblyOf<InvoiceMap>())
    .BuildSessionFactory();

映射：

public InvoiceMap()
{
    Id(x => x.InvoiceID, "InvoiceID");
    Map(x => x.InvoiceNumber);
    Map(x => x.InvoiceDate);
    Map(x => x.Company).CustomTypeIs<CompanyType>();
    Map(x => x.TransactionNumber).CustomTypeIs<TransactionNumberType>();
    Map(x => x.LongAddressBookNumber);
    Map(x => x.PurchaseOrderNumber);
    Map(x => x.ReceivedDateTime);
    Map(x => x.OCR);
    Map(x => x.DocumentNumber);
    Map(x => x.DocumentType);
    Map(x => x.PaymentStatus).CustomTypeIs<PaymentStatusType>();
    HasMany(x => x.Attestations)
        .KeyColumnNames.Add("InvoiceID")
        .Inverse()
        .Cascade.AllDeleteOrphan()
        .AsBag();
    HasMany(x => x.AttestationRequests)
        .KeyColumnNames.Add("InvoiceID")
        .Inverse()
        .Cascade.AllDeleteOrphan()
        .AsBag();
    HasMany(x => x.States)
        .KeyColumnNames.Add("InvoiceID")
        .Inverse()
        .Cascade.AllDeleteOrphan()
        .AsBag();
}

public AttestationMap()
{
    Id(x => x.ID, "AttestationID");
    Map(x => x.ReceivedAt);
    Map(x => x.IsInvalid, "Invalid");
    Map(x => x.InvalidationReason);
    Map(x => x.FileName);
    Map(x => x.FileData);
    References<EmployeeSnapshot>(x => x.Certifier, "Certifier")
        .Cascade.All()
        .FetchType.Join();
    References<Invoice>(x => x.Owner, "InvoiceID");
}

public AttestationReminderMap()
{
    Id(x => x.ID, "AttestationReminderID");
    Map(x => x.CC)
        .CustomTypeIs<RecipientType>();
    Map(x => x.Message);
    Map(x => x.SentAt);
    References<AttestationRequest>(x => x.Owner, "RequestID");
}

有什么想法吗？

谢谢，克里斯托弗

Answer 1

当你说什么都没有发生的时候，你的意思是如果不刷新数据库，什么都不会发生？

如果是这样，这是预期的行为。Flush告诉NHib将它在内存中的更改写入DB。

不知何故，我设法将会话的FlushMode设置为Never。正如查德向我描述的那样，这导致需要显式地调用Flush。当FlushMode将其保留为默认值时，并使用事务，实体将按预期更新。
