问题原因

flyway-core 8.2.1及以后的版本 单独包flyway-core 不再支持MySQL

解决方式

查询其他解决方式后有两种

1. 额外增加单独支持包

            <dependency>
                <groupId>org.flywaydbgroupId>
                <artifactId>flyway-mysqlartifactId>
            dependency>

2. 指定版本到 8.2.0 及之前即可，即降低版本
   手动指定 version 为 8.2.0 或以下 实际测试8.2.0 时依旧不行直接降低到7.10.0后恢复正常，或在 porperties 中指定版本，均可
