我想为我的 Play 应用配置 PostgreSQL,但出现以下错误:
! Internal server error, for request [GET /] ->

我使用以下配置文件:
应用程序.conf
db.default.url="postgres://play:play@localhost:9000/Play_Playground_DB"
db.default.user=play
db.default.password=play
db.default.driver=org.postgresql.Driver
项目/Build.scala
val appDependencies = Seq(
"postgresql" % "postgresql" % "9.1-901.jdbc4"
)
我设置Play_Playground_DB
并可以通过终端和命令访问它psql Play_Playground_DB
。
问题的根本原因可能是什么?
