我有一个问题是在Scaldi中注入光滑的DatabaseConfigProvider。它在游戏2.4中运行良好，但我不得不迁移到2.5。
这是我的配置：
我的申请表：
slick.dbs.devpostgres.driver="slick.driver.PostgresDriver$" # You must provide the required Slick driver!
slick.dbs.devpostgres.db.driver=org.postgresql.Driver
slick.dbs.devpostgres.db.url="jdbc:postgresql://localhost:5432/test"
slick.dbs.devpostgres.db.user=postgres
slick.dbs.devpostgres.db.password="pwd"
play.application.loader = scaldi.play.ScaldiApplicationLoader
play.modules {
enabled += modules.ApplicationModule
enabled += scaldi.play.ControllerInjector
}
我的Scaldi ApplicationModule：
class ApplicationModule extends Module {
binding to new ObjectDao
binding to new UserDao
bind[DatabaseConfig[_]] to DatabaseConfigProvider.get[JdbcProfile]("devpostgres")(inject[Application])
}
My UserDao由我的UserDao类扩展：
class ObjectDao(implicit inj: Injector) extends Injectable {
// Using the same database connection for every DAO extending this class
val dbConfig = inject[DatabaseConfigProvider].get[JdbcProfile]
val db = dbConfig.db
}
最后，我的UserDao：
class UserDao(implicit inj: Injector) extends ObjectDao {
import dbConfig.driver.api._
private val users = TableQuery[UserTable]
...
}
启动应用程序时出错：
