Hibernate Criteria Query

您的特定查询可能是：

crit.add(Restrictions.eq("a", "abc"));crit.add(Restrictions.in("b", new String[] { "def", "ghi" });

如果您想了解一般的AND和OR，请执行以下操作：

// Use disjunction() or conjunction() if you need more than 2 expressionsDisjunction aOrBOrC = Restrictions.disjunction(); // A or B or CaOrBOrC.add(Restrictions.eq("b", "a"));aOrBOrC.add(Restrictions.eq("b", "b"));aOrBOrC.add(Restrictions.eq("b", "c"));// Use Restrictions.and() / or() if you only have 2 expressionscrit.add(Restrictions.and(Restrictions.eq("a", "abc"), aOrBOrC));

这等效于：

where x.a = 'abc' and (x.b = 'a' or x.b = 'b' or x.b = 'c')
