保存时不使用 NHibernate 拦截器

Question

我有一个使用 Spring.Net 在 HibernateTemplate 中设置的 NHibernate 拦截器（我使用的是 ASP.NET MVC，fwiw），它用于审核。但是，由于某种原因，虽然当我调用 genericDAO.Get(id) 时会触发 OnLoad 方法，但当我尝试使用 genericDAO.SaveOrUpdate(object) 保存某些内容时，OnSave 或 OnFlushDirty 拦截器方法都不会被调用。有人知道为什么会这样吗？

我已经在 VS 调试器中的方法上设置了断点，因此我非常确定拦截器已设置并且我没有错过任何方法调用。显然，所有内容也都被正确保存和检索。

public class AuditInterceptor
    : EmptyInterceptor
{

     public override bool OnLoad(object entity, object id, object[] state, string[] propertyNames, IType[] types)
    {
        // Implementation
        // Called when using genericDAO.Get(id)
    }

    public override bool OnSave(Object entity, Object id, Object[] state,
        String[] propertyNames, IType[] types)
    {
        // Implementation
        // NOT called when using genericDAO.SaveOrUpdate(entity)
    }

    public override bool OnFlushDirty(Object entity, Object id,
        Object[] currentState, Object[] previousState,
        String[] propertyNames, IType[] types)
    {
        // Implementation
    }
}

这是我的objects.xml 文件的精简（匿名）版本：

  </object>

看来你没有使用交易。您应该尝试使用它们，如 Spring Nhibernate 示例（例如：）中所示，并激活日志记录以真正查看会话是否被刷新。

<!-- Hibernate Transaction Manager-->
<object id="hibernateTransactionManager" type="Spring.Data.NHibernate.HibernateTransactionManager , Spring.Data.NHibernate20">
<property name="DbProvider" ref="myDbProvider"/>
<property name="SessionFactory" ref="SessionFactory"/>
<property name="EntityInterceptor" ref="myAuditInterceptor"/>
</object>

您还声明了两个会话工厂。我猜这不相关，但这是故意的吗？
另外，Java spring 的相当旧的线程可能会有所帮助。
