我有一点弹簧启动应用程序。使用默认配置文件和mysql配置文件。默认情况下，我想以inMemory模式启动H2数据库。两个数据库我都用两个flyway文件初始化（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，那么我不会得到testdata，只有emtpy表。唯一不同的是，我在控制台中获得了4个hibernate外键错误。Flyway数据导入仅适用于MySQL，不适用于H2

解决方案：

application.properties

spring.jpa.hibernate.ddl-auto=none

，然后才上创建降。所以flyway设置数据库，hibernate将其删除并重新创建。为什么它在mysql数据库的mysql模式下工作我不知道。

可能是与外键和大小写转换的名称的问题。尝试命名FKS，如：

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

它没有影响。和以前一样的问题。 – Woody
