Hibernate - how to establish list of pojos?
原标题:Hibernate - how to create list of pojos?

我非常新。 我有MySQL数据库,绘制了诗歌。 我应该做些什么? 我从L.NET那里了解的光线-LINQ,并生成我地图绘制的物体清单。

因此,基本上,如果我想要把他们名单列入名单,以及团结和团结联盟对其采取行动,那么我在创建巴勒斯坦团结联盟之后的下一步措施是什么? 不仅在java物体中,也不会节省数据?

please see the hibernate document - Chapter 10. Working with objects http://docs.jboss.org/hibernate/core/3.3/reference/en/html/objectstate.html#objectstate-querying-executing

你们可以创造财富,或创建标准,以获得你们的候选人名单。 例如:

List cats = session.createQuery("from Cat").list();

List cats = session.createCriteria(Cat.class).list();
问题回答

回答你对《世界人权宣言》其余部分提出的问题,一旦你拿到你的物体清单,就如“qrtt1”所述,你就可以操纵本届会议的物体:

Session session = // obtain session
Transaction tx = session.beginTransaction();

List cats = session.createQuery("from Cat").list();

Cat firstCat = (Cat)cats.get(0);
firstCat.setName("Cooking Fat");
firstCat.setOwner("Richard O Sullivan");

// etc for other cats in the collection

tx.commit();
session.close();

您通过询问获得的任何物体均在tx.commit上被“ check脏检查”;这意味着在这种情况下,将为从询问中检索的第一个目录发布最新声明。
