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);
