使用 Slick 3.1 和 PlayFramework 2.5 Scala 进行进化时超时
Timeout when making an evolution with Slick 3.1 and PlayFramework 2.5 Scala
我目前正在开发一个 WebApp，以提高我在 Play Framework 和 Scala 方面的技能。
我已经学习了这个教程：http://pedrorijo.com/blog/play-slick/
我已将代码调整到我的用户对象（更改字段），但在全球范围内这与最终结果相同 (https://github.com/nemoo/play-slick3-example) 我还通过克隆 repo.The 来重现它唯一可能不同的是我正在使用 RDS 数据库来测试我的代码。
当我在没有 1.sql 的情况下启动索引页面时，它无法正常工作，这是正常的，它向我显示错误，提示 table 用户丢失
当我用 sequel pro 手动添加数据库中的 table 时，一切正常
但是，当我尝试通过 play-evolution 创建它时，出现了这个错误：
java.sql.SQLTimeoutException: Timeout after 1004ms of waiting for a connection.

我不知道为什么在手动完成时一切正常时我会超时。感谢所有帮助我的人！
那只是 Amazon RDS 实例的安全组问题，打开 3306 端口解决了问题:)
