玩！ 2.4 和 Evolutions 无法部署在 MySQL 数据库上

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 数据库上进行部署时，我收到以下错误：

[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？ 我是否必须在某个地方指定我将使用 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，​​升级到5.6版本（5.5不接受DateTime(6)）解决了这个问题。
