Hibernate 实体表无关联，多表查询

Criteria criteria = session.createCriteria(Bill.class, "b");
            DetachedCriteria categoryCriteria = DetachedCriteria.forClass(SxfWeChat.class, "s");
            categoryCriteria.add(Property.forName("s.id").eqProperty("b.id"));
            categoryCriteria.add(Restrictions.eq("s.status", "10"));
            criteria.add(Subqueries.exists(categoryCriteria.setProjection(Projections.property("s.id"))));
            List criteriaList = criteria.list();
