Flyway 发现多个具有版本的迁移

Question

我有两个sql文件，一个用于oracle，一个用于mySql数据库。路径如下

  db/migration/mysql/V1_1_migration.sql
  db/migration/oracle/V1_1_migration.sql

运行测试时，我遇到以下错误

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'flywayInitializer' defined in class path resource [org/springframework/boot/autoconfigure/flyway/FlywayAutoConfiguration$FlywayConfiguration.class]: Invocation of init method failed; nested exception is org.flywaydb.core.api.FlywayException: Found more than one migration with version 1.1
Offenders:
-> C:\code\service\db-repository\target\classes\db\migration\oracle\V1_1__migration.sql (SQL)
-> C:\code\service\db-repository\target\classes\db\migration\mysql\V1_1__migration.sql (SQL)

任何解决此错误的指针。

Flywaylocations属性需要一个{vendor}占位符，然后Spring Boot将从数据库驱动程序id的小写字母（h2、mysql、oracle等）中计算出目录，例如：

spring.flyway.locations=db/migration,db/migration/{vendor}

在上面的示例中，可以放入db/migration与供应商无关的脚本，也可以放入特定于供应商的脚本db/migration/oracle等。
