播放获取DatabaseConfigProvider的实例

Question

I'm use Slick as a Play module. In this way, DatabaseConfigProvider will be injected to Controller.
In a special stage, I want get DatabaseConfigProvider out of Controller.
How can I get DatabaseConfigProvider instance?

Answer 1

You can inject it like this:

class MyClass @Inject() (protected val dbConfigProvider: DatabaseConfigProvider)
    extends HasDatabaseConfigProvider[MyPostgresDriver]

With these imports:

import javax.inject.Inject
import database.MyPostgresDriver
import play.api.db.slick.{DatabaseConfigProvider, HasDatabaseConfigProvider}
import database.MyPostgresDriver.api._
