我试图找到以下问题的解决方案，但没有一个对我有用。我正在使用MySQL + flyway开发Angular + Spring Boot应用程序。请在此处指导问题所在。

答案 1

Flyway正在将SQL脚本的校验和与先前运行的校验和进行比较。如果您更改 Flyway 已应用的 SQL 脚本，则通常会发生此异常，从而导致校验和不匹配。

如果这是开发，则可以删除数据库并从头开始迁移。

如果您处于生产环境中，切勿编辑已应用的 SQL 脚本。以后只创建新的 SQL 脚本。


答案 2

这是我在本地系统中遇到此问题时对我有效的解决方案。

  1. 转到数据库中的flyway_schema_history
  2. 删除包含 sql 迁移脚本的行
