我正在尝试使用clearDB 在 Heroku 部署使用 play (scala) + play-slick 的应用程序，但出现以下错误：

2015-12-18T22:31:12.905287+00:00 heroku[web.1]: Process exited with status 255

the database url is something like (info [here](https://devcenter.heroku.com/articles/cleardb#configuring-your-ruby-application-to-use-cleardb)) and it's from clearDB:


slick.dbs.default.db.url = "jdbc:mysql://adffdadf2341:adf4234@us-cdbr-east.cleardb.com/heroku_db?reconnect=true"

据我所知，happened long time ago 与 play 1 相同。

我正在使用 play 2.4.4 和 play-slick 1.1.0。这是重新引入的错误吗？或者我错过了什么？是不是mysql驱动（已知）问题？

【问题讨论】：

标签： mysql scala jdbc playframework slick

【解决方案1】：

play-framework mailing list上的解决方案

排序答案：

“看起来 mysql jdbc 驱动程序无法解析输入字符串“8535...@eu-cdbr-west-01.cleardb.com”，这似乎不是源自 Play 或 play-光滑”

最终解决方案：

slick.dbs.default.driver = "slick.driver.MySQLDriver$"
slick.dbs.default.db.driver = "com.mysql.jdbc.Driver"
slick.dbs.default.db.url = "jdbc:mysql://eu-cdbr-west-01.cleardb.com/DATABASE"
slick.dbs.default.db.user = "USER"
slick.dbs.default.db.password = "PASS"
slick.dbs.default.db.connectionTimeout = 10 seconds

我知道 10 秒很长，只是为了测试。

【讨论】：

【解决方案2】：

MySQL 驱动程序将adffdadf2341:adf4234@us-cdbr-east.cleardb.com 视为host:port，因此它将adf4234@us-cdbr-east.cleardb.com 视为端口号并尝试将其转换为整数。

如果它们打算成为使用默认端口号的多个主机，请将 ':' 替换为 ','。

【讨论】：

nop，是clearDB提供的mysql url。此处信息：devcenter.heroku.com/articles/…
该链接未在 URL 中显示 jdbc: 前缀，并且将 URL 与 JDBC 一起使用的逻辑在 ':' 上拆分，并且使用 jdbc: 前缀，您已经引入了另一个 ':'，这可能会导致解析方式出现问题。
是的，为 slick 提供的 conf 是：slick.dbs.default.db.url = "jdbc:mysql://b20f74bc500d6a:8535df66@eu-cdbr-west-01.cleardb.com/ heroku_5adcda28b3b987e?reconnect=true" 那么，有没有转义字符之类的？
对不起，不熟悉ClearDB，只直接使用过MySQL JDBC驱动，但据我所知，没有转义字符（至少对于mysql）。如果您还没有，可能值得尝试从 url 中删除“jdbc:”并尝试一下。

【解决方案3】：

我认为问题在于您的框架无法吞下整个 mysql url。您需要将其解析为其组件（用户名、密码、主机名、数据库名称）并将它们填充到适当的字段中。
