hibernate Criteria 的使用

方法	说明
Restrictions.eq	＝
Restrictions.allEq	利用Map来进行多个等于的限制
Restrictions.gt	＞
Restrictions.ge	＞＝
Restrictions.lt	＜
Restrictions.le	＜＝
Restrictions.between	BETWEEN
Restrictions.like	LIKE
Restrictions.in	in
Restrictions.and	and
Restrictions.or	or
Restrictions.sqlRestriction	用SQL限定查询

Criteria query = HibernateUtil.getSession().createCriteria(Entity.class);

if (Id > 0)

{

query.add(Restrictions.eq(id,
Entity.getId()));

}

if (title != null )

{

query.add(Restrictions.like(TITLE,
Entity.getTitle(), MatchMode.ANYWHERE));

}

if (Entity.getStatus() > -1)

query.add(Restrictions.in(STATUS, ArrayUtils.toObject(new int[] { 0, 1 })));

}

if (Entity.getEndTime() > 0 &&

Entity.getStartTime() > 0)

{

query.add(Restrictions.or(

Restrictions.between(START_TIME,
Entity.getStartTime(),

Entity.getEndTime()),

Restrictions.between(END_TIME,
Entity.getStartTime(),
Entity.getEndTime())));

// query.add(Restrictions.ge(START_TIME,
Entity.getStartTime()));

// query.add(Restrictions.le(END_TIME,
Entity.getEndTime()));

}

query.addOrder(Order.asc(START_TIME));

query.add(Restrictions.sqlRestriction("{alias}.id in (select id from user where manager_id = "+managerId+")"));

return query.list();

备注：

hibernate的查询,其中学到构建Criteria查询,在Criteria查询中

使用sqlRestriction()方法来提供SQL语法作限定查询,如:

Criteria
criteria = session.createCriteria(User.class);
criteria.add(Restrictions.sqlRestriction(“{alias}.name
LIKE(?)", "cater%", Hibernate.STRING));
List users = criteria.list();
