hibernate Criteria中or的用法

Java代码







//s筛选去除无效数据
/* detachedCriteria.add(
Restrictions.or(
Restrictions.like("chanpin", "冰箱", MatchMode.ANYWHERE),

Restrictions.or(
Restrictions.like("chanpin", "洗衣机", MatchMode.ANYWHERE),

Restrictions.or(
Restrictions.like("chanpin", "热水器", MatchMode.ANYWHERE),

Restrictions.like("chanpin", "空调", MatchMode.ANYWHERE))))

);
*/
Disjunction dis=Restrictions.disjunction();
dis.add(Restrictions.like("chanpin", "冰箱", MatchMode.ANYWHERE));
dis.add(Restrictions.like("chanpin", "洗衣机", MatchMode.ANYWHERE));
dis.add(Restrictions.like("chanpin", "热水器", MatchMode.ANYWHERE));
dis.add(Restrictions.like("chanpin", "空调", MatchMode.ANYWHERE));
detachedCriteria.add(dis);
//e筛选去除无效数据

//s筛选去除无效数据
/*		detachedCriteria.add(
Restrictions.or(
Restrictions.like("chanpin", "冰箱", MatchMode.ANYWHERE),

Java代码







Restrictions.disjunction();用来组合一组逻辑或条件【or】

Restrictions.disjunction();用来组合一组逻辑或条件【or】

Java代码







Restrictions.conjunction();用来组合一组逻辑与条件【and】

Restrictions.conjunction();用来组合一组逻辑与条件【and】

注释掉部分的代码，查询结果和下面的代码一样，如果针对一个字段写多个逻辑或条件的话，用下面的方式比较好。根据具体情况选择合适的方法。
