播放2.6演进数据库更改未应用

我通过以下方式解决了它 the documentation 升级到2.6以后

这是我的密码

import play.api.ApplicationLoader.Context
import play.api.{Application, ApplicationLoader, BuiltInComponentsFromContext}
import play.api.db.{DBComponents, HikariCPComponents}
import play.api.db.evolutions.EvolutionsComponents
import play.api.routing.Router
import play.filters.HttpFiltersComponents
import router.Routes

class MyApplicationLoader extends ApplicationLoader {

  def load(context: ApplicationLoader.Context): Application = {
    new AppComponents(context).application
  }
}

class AppComponents(context: Context)
    extends BuiltInComponentsFromContext(context)
    with DBComponents
    with EvolutionsComponents
    with HikariCPComponents
    with HttpFiltersComponents {
  // this will actually run the database migrations on startup
  applicationEvolutions

  //  val prefix: String = "/"
  lazy val router = Router.empty
  //  lazy val router: Router = bind(classOf[Routes]).to(classOf[Routes])

}

在conf/application.conf中添加这一行

play.application.loader=MyApplicationLoader
