删除父实体抛出 org.h2.jdbc.JdbcSQLIntegrityConstraintViolationException: 参照完整性约束冲突

问题描述

所以我有两个表：projectStatus 和 projectStatusHistory。
创建新项目时，会在 projectStatus 表中插入一条新记录。一旦项目启动或状态改变，就会在projectStatusHistory表中插入一条记录（记录内容来自projectStatus表），然后在projectStatus表中更新项目状态。当一个项目完成后，我们会将最后一条记录归档到历史表中，projectStatus 表将不再有该项目的记录。

但是 projectStatusRepository.delete(projectStatusId) 抛出异常

引起：org.h2.jdbc.JdbcsqlIntegrityConstraintViolationException：违反参照完整性约束：“FKIB57NUSJBIJ4K8G83MFNY6V06 ...
