Hibernate条件限制和/或组合

如何使用hibernate限制来实现此目的?

(((A='X') and (B in('X',Y))) or ((A='Y') and (B='Z')))

回答:

认为有效

Criteria criteria = getSession().createCriteria(clazz); 

Criterion rest1= Restrictions.and(Restrictions.eq(A, "X"),

Restrictions.in("B", Arrays.asList("X",Y)));

Criterion rest2= Restrictions.and(Restrictions.eq(A, "Y"),

Restrictions.eq(B, "Z"));

criteria.add(Restrictions.or(rest1, rest2));
