尝试从 JDBC 元数据解析外键元数据时未能找到外键的列映射

Question

hibernate 在第一个运行上正确地创建和填充数据库。在第二个运行上，我遇到以下错误。

Hibernate 5.2.0 和 Oracle 12c。这是一个错误吗？我几乎找不到任何资料，当我 google this.

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

Answer 1

看来5.2.0确实有bug。使用 5.1.0 我没有问题。

Answer 2

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