jhipster 添加 2 个现有表之间的关系

Question

我添加了 2 个现有表之间的关系，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：

我需要做什么才能在现有表上添加关系？

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

谢谢！

Answer 1

如果您不在生产环境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程序重新创建它。

否则，请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 校验它们的原因，当你想向过去的结构中添加一些东西时，你应该添加新的迁移而不是修改旧的。
