Java 如何启用DDL事务支持？

我刚开始使用flywaydb，只是为了测试创建和插入查询，并启动了迁移，但它忽略了我的所有创建表脚本：

我使用-X选项进行调试，发现一行奇怪的代码 调试：支持的DDL事务：false

看来如果我真的做到了，它会成功的

是否有人面临这个问题，如果是，如何摆脱这个问题？ 我已经在新模式上使用cleaninitmigrate完成了这项工作 全文如下：

这仅仅意味着您的数据库不支持DDL事务。如果需要，请使用不同的方法，如PostgreSQL、DB2或SqlServer

至于为什么你的剧本没有被采纳，这是不可能从你的问题中分辨出来的

从入门教程开始，一旦成功，就将其应用于您的项目。

嗨，Axel，我正在使用mysql，这个问题是我从入门教程中得到的。如果您完全按照步骤操作，它就会起作用。发布一个飞行路线清理，然后再试一次。@alex fontaine，我按照您在中所说的做了，只是我使用的是mysql。init和clean正在工作，但对于忽略V1_ucr_tbl.sql的迁移，我已经更新了原始问题中的完整stacktrace跳过init。它仅适用于现有的dbs。仍然失败：，我发现该过程适用于H2数据库，但不适用于MySQL。
