欢迎任何关于此异常的根本原因的想法。

我看到了同样的错误，但我已经设法解决了这个问题。我在documentation中偶然发现了这一点：“许多JPA实现在为JPA所需的每个@JoinColumn注释未指定referencedColumnName时可能会抛出看似不一致的异常（即使所有引用的列名都等于引用表中的名称））“。为每个JoinColumn添加referencedColumnNames似乎为我解决了这个问题。

为了帮助缩小哪个类给我带来麻烦，我在org.hibernate.cfg.annotations.TableBinder :: bindFk（）中设置了一个断点，在第682行，他们调用referencedColumn = buildingContext.getMetadataCollector().getPhysicalColumnName(table, referencedColumn);寻找{ {1}}为空或为空。
