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" 

至于我已经看到相同的问题happened long time ago，与播放1.

我正在使用播放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？这是一个MySQL驱动程序（已知）的问题？

Answer 1

解决方案：

"it looks like the mysql jdbc driver is failing to parse the input string "8535...@eu-cdbr-west-01.cleardb.com”, and that doesn’t seem to originate from Play or play-slick"

最终的解决方案：

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 

我了解的10秒钟，这两点是很多，使得它只是为了测试。

Answer 2

MySQL驱动程序正在处理adffdadf2341:adf4234@us-cdbr-east.cleardb.com为host:port，所以它将adf4234@us-cdbr-east.cleardb.com作为端口号，并试图将其转换为整数。

如果这些打算使用默认端口号为多个主机，请将'：'替换为'，'。

Answer 3

我认为问题是你的框架不能吞下整个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）并将其填入适当的字段。在play-framework mailing list
