Hibernate 未正确解析 DST 转换周围的值

Question

我遇到了一个问题，在 DST 转换期间发生的 Instant 被正确地保存到数据库中，但是当回读时返回不同的值。

具体来说，我在 Europe/London 并且 2021-10-31T01:04:00Z 有问题 - 我回来的瞬间是 2021-10-31T00:04:00Z.

我已经创建了一个简单的应用程序来演示这一点 - 它持续存在三个事件，一个在 DST 转换之前，一个是之前提到的唯一一个在 DST 转换期间，然后一个在 DST 转换之后。我希望输入和输出数据始终相同。

输出如下：

ZoneId=Europe/London

有趣的是，如果我迁移到 Hibernate v6，它看起来能正常工作吗？

明确地说： Europe/London 时区， H2 内存数据库。

Answer 1

我通过将 AvailableSettings.JDBC_TIME_ZONE 设置为 UTC 并将列类型更改为 TIMEZONE.

来完成此工作

我相信这是 Hibernate v5 和 H2 驱动程序之间的不兼容。
