Question

我有一个工作的游戏框架应用程序。我试图在应用程序上启用数据库演化支持。我通过添加以下设置更改了application.conf文件]

db.default.driver=org.postgresql.Driver
db.default.url="jdbc:postgresql://localhost:5432/scaladb"
db.default.username=scalauser
db.default.password=******
db.default.poolInitialSize=1
db.default.poolMaxSize=5
db.default.ConnectionTimeoutMillis=1000
play.evolutions.autoApply=true
该数据库已存在，我可以使用类似sql -U scalauser -d scaladb的命令连接到它>
我将以下行添加到我的AppLoader类中，以设置数据库并运行迁移

val onStart = {
  applicationEvolutions
  DBs.setupAll()
}

applicationLifecycle.addStopHook{() => 
  DBs.closeAll()
  Future.successful(Unit)
}
但是现在当我用set run运行我的应用程序时，我得到了这个神秘的错误消息，它实际上没有任何意义。我什至不确定这是试图告诉我的框架

Answer 1

确定。我想到了。问题是配置文件格式错误。线

db.default.driver=org.postgresql.Driver
db.default.username=scalauser
db.default.password=******
