休眠軟刪除仍在刪除我的記錄

Question

我正在嘗試使用 Hibernate 實現軟刪除，但由於某種原因，我的記錄仍然被刪除。 誰介意看看。

public class SoftDeleteEventListener extends DefaultDeleteEventListener {

private static final long serialVersionUID = 1L;

@SuppressWarnings("rawtypes")
@Override
public void onDelete(DeleteEvent event, Set transientEntities) throws HibernateException {
    Object dbEntity = event.getObject();

    if (dbEntity instanceof Entity) 
    {
        ((Entity)dbEntity).setDeleted(true);
        ((Entity)dbEntity).setDeletedOn(new Date());

        EntityPersister persister = event.getSession().getEntityPersister( event.getEntityName(), dbEntity);
        EntityEntry entityEntry = event.getSession().getPersistenceContext().getEntry(dbEntity);

        cascadeBeforeDelete(event.getSession(), persister, dbEntity, entityEntry, transientEntities);
        cascadeAfterDelete(event.getSession(), persister, dbEntity, transientEntities);
    } else {
        super.onDelete(event, transientEntities);
    }
}

}

這就是我注冊會話/監聽器的方式

Configuration configuration = new Configuration();
        configuration.configure();
        StandardServiceRegistryBuilder ssrb = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
        sessionFactory = configuration.buildSessionFactory(ssrb.build());

        EventListenerRegistry registry = ((SessionFactoryImpl)sessionFactory).getServiceRegistry().getService(
        EventListenerRegistry.class);
        registry.getEventListenerGroup(EventType.DELETE).appendListener(new SoftDeleteEventListener());

Answer 1

要解決此問題：

1. 你需要定義一個deleted列

2. 而且，您需要用

    @SQLDelete(sql="UPDATE customer SET deleted = true WHERE id = ?")

這比使用 Hibernate Interceptor 簡單得多。

我會嘗試一個更簡單的版本：

if (dbEntity instanceof Entity) 
{
    ((Entity)dbEntity).setDeleted(true);
    ((Entity)dbEntity).setDeletedOn(new Date());

    event.getSession().mergedbEntity
} else {
    super.onDelete(event, transientEntities);
}
