玩！ 2.4 和 evolutions 无法在 MySQL 数据库上部署

Question

我正在尝试部署 Play！ 2.4项目，使用eBeans和Evolutions。

但是，当尝试在 MySQL 数据库上部署时，出现以下错误：

[error] p.a.d.e.DefaultEvolutionsApi - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'sequence donation_seq' at line 1 [ERROR:1064, SQLSTATE:42000]
Oops, cannot start the server.

我该如何解决这个问题？我是否必须在某处指定我将使用 MySQL 数据库进行生产，以便创建与 MySQL 兼容的 SQL 语法？

我确实将 H2 设置为 MYSQL 模式：db.default.url="jdbc:h2:mem:play;MODE=MYSQL"

Answer 1

使用 mySql 作为我的开发数据库并升级到版本 5.6（5.5 不接受 DateTime(6)）解决了这个问题。
