Restrictions.or多个条件用法
两个条件或查询：
Restrictions.or(Restrictions.in("username",list1),Restrictions.idEq(1));
三个或多个条件查询:（使用嵌套方式）
criteria.add(Restrictions.or(
Restrictions.in("username",list1),
Restrictions.or(Restrictions.idEq(3),Restrictions.idEq(4))
)
);
Restrictions.or(Restrictions.like(),Restrictions.or(Restrictions.like,........))
里面的or可以无限加的.还是比较好用
Session session = getHibernateTemplate().getSessionFactory()
.openSession();
Criteria criteria = session.createCriteria(Film.class);
List<Film> list = criteria.add(
Restrictions.or(Restrictions.like("description", key,MatchMode.ANYWHERE),
Restrictions.or(Restrictions.like("name", key,MatchMode.ANYWHERE),
Restrictions.or( Restrictions.like("direct", key,MatchMode.ANYWHERE),
Restrictions.or(Restrictions.like("mainplay",key,MatchMode.ANYWHERE),
Restrictions.like("filearea", key,MatchMode.ANYWHERE)))))).list();
session.close();
return list;
第二种方法
Disjunction dis=Restrictions.disjunction();
dis.add(Restrictions.like("username", a.getUsername(),MatchMode.ANYWHERE));
dis.add(Restrictions.like("real_name", a.getUsername(),MatchMode.ANYWHERE));
criteria.add(dis);
