Question

嗯，我有一个非常简单的方法，它应该返回一些代码...而且确实如此，但顺序并不起作用。

private List<Code> get(String qualifier, ZonedDateTime validAt) {
    return em.createQuery(
              "select c\n"
            + "  from Code c\n"
            + " where c.qualifier = :qualifier\n"
            + "   and c.validFrom <= :validAt)\n"
            + "   and c.validUntil > :validAt)\n"
            + " order by c.sequence, c.code\n",
            com.service.code.impl.model.Code.class)
        .setParameter("qualifier", qualifier)
        .setParameter("validAt", validAt)
        .getResultList().stream()
        .map(converter::convert)
        .collect(Collectors.toList());
}

当我调用方法时，我会记录语句，这就是它的样子：

如您所见，缺少订单。怎么可能呢？

你应该从最后两行中删除)，如下所示;）

private List<Code> get(String qualifier, ZonedDateTime validAt) {
    return em.createQuery(
              "select c\n"
            + "  from Code c\n"
            + " where c.qualifier = :qualifier\n"
            + "   and c.validFrom <= :validAt\n"
            + "   and c.validUntil > :validAt\n"
            + " order by c.sequence, c.code\n",
            com.service.code.impl.model.Code.class)
        .setParameter("qualifier", qualifier)
        .setParameter("validAt", validAt)
        .getResultList().stream()
        .map(converter::convert)
        .collect(Collectors.toList());
}

订单不会显示在日志中
