jhipster 添加2个现有表之间的关系

Question

我在 2 个现有表之间添加了关系，并使用函数“jhipster import-jdl”重新生成，但是当我启动应用程序时，liquibase 出现错误：

如何在现有表上添加关系？

我必须手动为 liquibase 添加 xml 更改日志吗？并更新校验和？？

谢谢！

如果您不在生产中并且没有要保留的数据，只需删除您的数据库并让您的应用重新创建它。

否则，手动创建新迁移或使用 liquibase diff 添加关系。迁移应该是不可变的，这就是 Liquibase 对它们进行校验和的原因，当您想向过去的结构添加某些内容时，您应该添加新的迁移而不是修改旧的迁移。
