HSQLDB批量删除失败，但在Oracle中可以正常工作

我有一个设置：Spring+Hibernate+JPA+Junit来测试我的代码

我有Oracle作为数据库。当我测试代码时，每个测试都通过了。这段代码甚至在生产中。我想在junit的内存中使用HSQLDB，而不是Oracle。大多数测试仍然通过HSQLDB，但有一个特定的测试总是失败。在甲骨文公司工作

这是引起麻烦的线路。我使用log4jdbc输出sql语句

为两条语句创建批处理：

1：从图像\u标记中删除，其中图像\u标记\u键=1

2：从图像\u标记中删除，其中图像\u标记\u键=2

在JPA中，我希望实体删除它们。在第一次迭代中效果很好，但是当我到达第二个项目时，它失败了，出现了以下异常：

异常的原因org.hibernate.StaleStateException主要是由于

Hibernate缓存会话中的对象。如果对象是 修改后，Hibernate不知道，它会抛出这个 例外

或

在提交对象之前刷新数据可能会导致清除所有 持久化的对象挂起

我建议设置spring和log4jdbc的日志级别来调试和启用hibernate的show_sql，这将为您提供清晰的思路

更新

乍一看，我认为：

---

在第一次迭代中，当您说Delete IMAGE_TAGS_KEY 1和KEY 2时，hibernate会触发此查询，这样您就可以通过log4jdbc记录此查询，但仍然没有提交事务，所以更改仍然没有写入DB，在第二次迭代中，您再次删除相同的键，这些键将被挂起以得到反映。

我以为发生了什么。只是不知道为什么它可以在Oracle上正常工作，但不能在HSQLDB上正常工作。我将重写查询并再次测试它。
