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），它用于审计。但是，出于某种原因，当我调用genericDAO.Get（id）时触发OnLoad方法，当我尝试使用genericDAO.SaveOrUpdate（object）保存某些东西时，既不调用OnSave或OnFlushDirty Interceptor方法。谁知道为什么会这样？

我在VS调试器中的方法上设置了断点，所以我非常确定Interceptor已经设置并且我没有错过任何方法调用。显然，一切都在正确保存和检索。

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文件的缩减（和匿名）版本：

  <object id="MyController" singleton="false" type="Project.Web.Controllers.MyController">
    <constructor-arg name="dashboardService" ref="DashboardService" />
  </object> 

<object id="DashboardService" type="Project.Business.Services.DashboardService, Project.Business">
    <constructor-arg name="dashboardDao" ref="DashboardDao" />
  </object>  

<object id="DashboardDao" type="Project.Data.Dao.DashboardDao, Project.Data">

  <object id="SessionFactory" type="Spring.Data.NHibernate.LocalSessionFactoryObject, Spring.Data.NHibernate20">

您似乎不使用交易。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>

您还要声明两个会话工厂。这与我猜不相关，但这是故意的吗？对于Java的春天，这个rather old thread也许会有所帮助。
