Hibernate在第一次运行时正确地创建并填充了数据库。在第二次运行时，我得到了低于错误的结果。
Hibernate 5.2.0和Oracle 12c。这是个窃听器吗？当我搜索这个的时候，我几乎找不到任何信息。
@ManyToOne
@JoinColumn(name="fk_report")
@ForeignKey(name="fk_report")
private Report report;堆栈跟踪：

看起来这是Hibernate 5.2.0中引入的错误-应该在下一个次要版本(5.2.1)中修复：https://hibernate.atlassian.net/browse/HHH-10802

看起来5.2.0确实有一个错误。在5.1.0版本中，我没有任何问题。

我的回复可能晚了，但是对于那些将来可能会遇到它的人，您可以使用不同的模式或转到MySQL，然后选择有问题的表并转到“ALTER TABLE”，然后右键单击并删除选定的FOREIGN_KEY。我有这个过程的截图。

注意：确保您删除的外键是控制台错误中显示的外键。
