本文整理了Java中org.hibernate.Query类的一些代码示例，展示了Query类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Query类的具体详情如下：
包路径：org.hibernate.Query
类名称：Query

Query介绍

[英]Represents an HQL/JPQL query or a compiled Criteria query
[中]表示HQL/JPQL查询或编译条件查询

代码示例

/**
 * Call setEntity() on a cacheable query - see FORGE-265
 */
public List listEventsOfOrganizer(Person organizer) {
  Session session = sessionFactory.getCurrentSession();
  session.beginTransaction();
  Query query = session.createQuery("from Event ev where ev.organizer = :organizer");
  query.setCacheable(true);
  query.setEntity("organizer", organizer);
  List result = query.list();
  session.getTransaction().commit();
  return result;
}

 return new HandlingHistory(getSession().createQuery(
     "from HandlingEvent where cargo.trackingId = :tid").
     setParameter("tid", trackingId).
     list()
 );
}
