NHibernate 从 DateTime 变量截断毫秒

Question

我该如何解决这个问题？ NHibernate 从 DateTime 变量中截断毫秒数

DataHoraRecebimento = DateTime.Now;
DataReferencia = new DateTime(2015, 9, 8, 17, 0, 50, 332);

即使我配置了 de LongTimePattern:

这是我在 hbm 上的配置：

版本 3.1.0.4000， xmlns="urn:nhibernate-mapping-2.2", MsSql2008方言

 <class name="MensagemRecebimento" table="dbo.xxx" lazy="true" dynamic-update="true">

    <id name="CodigoRecebimentoMensagem" column="COD_RECB_MSG"><generator class="identity" /></id>
    <property name="DataReferencia"><column name="DATA_REF_MSG" sql-type="datetime" not-null="true" /></property>
    <property name="DataHoraRecebimento"><column name="DTHR_RECB_MSG" sql-type="datetime" not-null="true" /></property>

  </class>

这是保存我的对象的代码

NHibernateSessionHelper.Instance.GetSession().Save(obj);

这里是nHibernate保存后生成的查询结果您会注意到毫秒为零

NHibernate:
    INSERT
    INTO
        dbo.xxx
        (DATA_REF_MSG, DTHR_RECB_MSG)
    VALUES
        (@p7, @p8);
    select
        SCOPE_IDENTITY();

    @p7 = 08/09/2015 17:00:50.000 [Type: DateTime (0)],
    @p8 = 19/08/2016 12:42:48.000 [Type: DateTime (0)]

我得到了答案，我将type="Timestamp"添加到hbm.xml

<class name="MensagemRecebimento" table="dbo.xxx" lazy="true" dynamic-update="true">

  <id name="CodigoRecebimentoMensagem" column="COD_RECB_MSG"> <generator class="identity" /> </id>
  <property name="DataReferencia" type="Timestamp"> <column name="DATA_REF_MSG" sql-type="datetime" not-null="true" /> </property>
  <property name="DataHoraRecebimento" type="Timestamp"> <column name="DTHR_RECB_MSG" sql-type="datetime" not-null="true" /></property>

</class>
