mysql - Flyway数据导入仅适用于MySQL，不适用于H2

Question

我有一个小的 Spring Boot 应用程序。具有默认配置文件和 mysql 配置文件。默认情况下，我想在内存模式下启动 H2 数据库。我使用两个 Flyway 文件初始化这两个数据库(数据库设置和一些测试数据)。 如果我在 mysql 模式下运行我的应用程序，一切正常。如果我在默认模式下运行应用程序，我不会得到测试数据，只会得到空表。唯一的不同是，我在控制台中收到 4 个 hibernate 外键错误。

Answer 1

可能是外键名称和大小写转换的问题。尝试将您的 FK 命名为:

CONSTRAINT FK_ADDRESS_COMPANY FOREIGN KEY (COMPANY_ID) REFERENCES COMPANY(ID)
