java - 无法在 Hibernate Criteria 中获取两个日期之间的数据

Question

令人惊讶的是，我无法获取两个日期之间的字段之和 我的方法是:

public static double getTotalfeeIncome(Date fromDate, Date toDate) {
        Session session = HibernateUtil.getSessionFactory().openSession();
        Transaction tx = null;
        double total = 0.0;
        try {
            tx = session.beginTransaction();
            Criteria cr = session.createCriteria(StudentFees.class);
            cr.add(Restrictions.eq("delFlg", "N"));
            cr.add(Restrictions.between("paymentDate", fromDate, toDate));
            log.debug(fromDate);
            log.debug(toDate);
            total = (Double) cr.setProjection(Projections.sum("paymentAmt")).uniqueResult();
            tx.commit();
        } catch (Exception asd) {
            log.debug(asd.getMessage());
            if (tx != null) {
                tx.rollback();
            }
        } finally {
            session.close();
        }
        return total;
    }

当我尝试获取值时:

double feeIncome = Expense.getTotalfeeIncome(fdate, tdate);

返回 0，但两个日期之间有数据。我的 catch 部分中似乎没有打印出一个错误。我的记录器输出是:

[edulogger] [11 Mar 2017 - 18:54:48] [DEBUG][dao.Expense][getTotalfeeIncome] - Sat Mar 11 00:00:00 EAT 2017

我做错了什么？

Answer 1

使用以下内容

cr.add(criteria.add(Restrictions.ge("paymentDate", fromDate))); 
cr.add(criteria.add(Restrictions.lt("paymentDate", toDate)));

而不是

cr.add(Restrictions.between("paymentDate", fromDate, toDate));

更新:

cr.add(Restrictions.between("DATE(paymentDate)", fromDate, toDate));
