欢迎对此异常的根本原因有任何想法。
最佳答案
我看到了同样的错误，但已设法解决了。我在documentation中偶然发现了这个问题:“许多JPA实现可能在未为每个@JoinColumn批注指定指定referencedColumnName时抛出看似不一致的异常，这是JPA要求的(即使所有引用的列名都等于引用表中的列名)。”为每个JoinColumn添加referencedColumnNames似乎为我解决了。
为了帮助缩小哪个类给我带来的麻烦，我在第682行的org.hibernate.cfg.annotations.TableBinder::bindFk()中设置了一个断点，它们在调用referencedColumn = buildingContext.getMetadataCollector().getPhysicalColumnName(table, referencedColumn);时查找referencedColumn为空或空。
