休眠標準限制和/或組合

Question

我將如何使用Hibernate限制來實現這一點？

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

Answer 1

想到工作

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));
