我正在尝试一个非常简单的 Fluent Nhibernate 示例：带有一个表的 SQL 2005 数据库，VS2008 控制台应用程序。该表在程序开始前有一条记录。

我正在尝试添加一条记录，然后显示表中的所有记录。程序成功编译运行，没有任何异常，但是没有显示记录。也不会创建 HBM 映射文件。看起来程序完全忽略了数据库（尽管它连接到它）。

这是我的代码 - 我尽量保持最小：

实体：

namespace FluentNhibernationConsole.Entities
{
    public class Sorder
    {
        public virtual int Id { get; private set; }
        public virtual DateTime DateCreated { get; set; }

    }
}

映射：

namespace FluentNhibernationConsole.Mappings
{
    class SorderMap : ClassMap<Sorder>
    {
        public SorderMap()
        {
            Id(x => x.Id, "SorderId");
            Map(x => x.DateCreated);
        }
    }
}

程序本身：

namespace FluentNhibernationConsole
{
    class Program
    {
         private static ISessionFactory CreateSessionFactory()
        {
            return Fluently.Configure()
                .Database(MsSqlConfiguration
                    .MsSql2005
                    .ShowSql()
                    .ConnectionString(@"server=.\sqlexpress;database=lsdb;Integrated Security=SSPI;")
                )
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<Program>()
                    .ExportTo(@"d:\temp\nh")
                )
                .BuildSessionFactory();
        }

        static void Main(string[] args)
        {
            var sessionFactory = CreateSessionFactory();
            using (var session = sessionFactory.OpenSession())
            {
                using (var transaction = session.BeginTransaction())
                {
                    var order1 = new Sorder {DateCreated = DateTime.Now};
                    transaction.Commit();
                }
                using (session.BeginTransaction())
                    foreach (var order in session.CreateCriteria(typeof(Sorder)).List<Sorder>())
                        Console.WriteLine("Order: " + order.DateCreated.ToLongTimeString());
            }
            Console.ReadKey();
        }

    }
}

As you have already noted, you forgot to Save() your new entity.

using (var transaction = session.BeginTransaction())
{
    var order1 = new Sorder {DateCreated = DateTime.Now};
    session.Save( order1 );
    transaction.Commit();
}

And your ClassMap should be public

public class SorderMap : ClassMap<Sorder>
