Question

我正在尝试为Slick 3.0.3项目配置Play Framework 2。这是我的配置application.conf

db.default.url="jdbc:mysql://localhost/entquiz?characterEncoding=UTF-8"
db.default.driver="com.mysql.jdbc.Driver"
db.default.user=entquiz
db.default.pass="qFbR3CW6"
db.default.host="localhost"

在我的代码中，我正在尝试与

连接

val db = Database.forDataSource(DB.getDataSource())

我使用的内容无关紧要（forDataSource或forConfig）我得到同样的错误

Slick error : jdbc driver not defined in application.conf 
for db.driver.MySQL.defaultStringType.driver key

在谷歌搜索没有结果。

这是完整堆栈跟踪

事实证明，问题在于evolutions插件。在添加了play-slick-evolution依赖之后，问题就消失了。

build.sbt

"com.typesafe.play" %% "play-slick" % "1.1.0"
"com.typesafe.play" %% "play-slick-evolutions" % "1.1.0"

我的游戏框架也是2.3.8，光滑3.0仅适用于2.4

plugins.sbt

addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.4.2")

Play Framework Slick 3.0.3 Mysql
