Question

hibernate在第一次运行时正确创建并填充数据库。在第二轮，我得到以下错误。

Hibernate 5.2.0和Oracle 12c。这是一个错误吗？当我谷歌这个时，我几乎找不到任何信息。

    @ManyToOne
    @JoinColumn(name="fk_report")
    @ForeignKey(name="fk_report")
    private Report report;

Answer 1

看起来这是Hibernate 5.2.0中引入的一个错误 - 应该在下一个次要版本（5.2.1）中修复： https://hibernate.atlassian.net/browse/HHH-10802

Answer 2

看起来像5.2.0确实有一个bug。使用5.1.0我没有问题。
