很多网上关于Flyway整合springboot的说明并不明确

Flyway在6.0之前是有兼容的，在6.0之后是没有做兼容的，小编的版本是6.0+

报错如下:

• 原因一：版本过高，表名变成了flyway_schema_history

解决：

flyway:
      baseline-on-migrate: true
      encoding: utf-8   #字符编码
      out-of-order: true #是否允许无序的迁移
      enabled: true #是否启用flyway
      table: schema_version
      validate-on-migrate: true

官方建议是配置table：schema_version

• 原因二：

sql语句执行错误，其实就是你的脚本有问题，找到schema_version 删除出错的脚本的记录，然后修改脚本再重新执行即可
