c# - 软删除 - ActiveRecord with Listeners

Question

我正在将 ActiveRecord 与 nHibernate 一起使用，并试图实现软删除，以便将对象标记为“IsDeleted”，而不是实际删除它们。我显然需要级联选项才能工作。

[assembly: AddEventListener(typeof(MyNamespace.SoftDeleteListener))] namespace MyNamespace { public class SoftDeleteListener : DefaultDeleteEventListener
{
    protected override void DeleteEntity(IEventSource session, object entity, EntityEntry entityEntry, bool isCascadeDeleteEnabled,
        IEntityPersister persister, ISet transientEntities)
    {
        if (entity is IPermanentRecord)
        {
            ((IPermanentRecord)entity).IsDeleted = true;
            this.CascadeBeforeDelete(session, persister, entity,
                entityEntry, transientEntities);
            this.CascadeAfterDelete(session, persister, entity, transientEntities);
        }
        else
        {
            base.DeleteEntity(session, entity, entityEntry,
                isCascadeDeleteEnabled, persister, transientEntities);
        }
    }
}

我的实体 - “产品”实现

interface IPermanentRecord
{
    bool IsDeleted { get; set; }
}

问题是，当删除它只是删除实体时，监听器不会被触发!

任何有兴趣的人...

我找到了 nHibernate 配置并手动添加了监听器，它触发了..

foreach (NHibernate.Cfg.Configuration cfg in ActiveRecordMediator.GetSessionFactoryHolder().GetAllConfigurations())
        {
            cfg.SetListener(ListenerType.Delete, new SoftDeleteListener());
            cfg.AddAssembly(assem);
        }
