与Scala玩框架，无法连接到数据库JDBC Postgresql

我正在关注"Play for Scala"书。我目前正试图建立一个连接到我的机器上运行的PostgreSQL数据库，但是我无法连接，我不知道为什么。我的一名同事也有一个使用Play with PostgreSQL的项目，该项目被克隆到运行PostgreSQL的同一台机器上，并且工作得很好。与Scala玩框架，无法连接到数据库JDBC Postgresql

我收到以下错误：

[info] - application - Creating Pool for datasource 'default' 
[error] - application -

这里是application.conf相关代码：

db.default.driver=org.postgresql.Driver 
db.default.url="jdbc:postgresql://localhost:5432/paperclips" 
db.default.username="postgres" 
db.default.password="postgres"

而且在构建文件：

libraryDependencies ++= Seq(
    "com.typesafe.play" %% "anorm" % "2.4.0", 
    "com.adrianhurt" %% "play-bootstrap3" % "0.4.5-P24", 
    "net.sf.barcode4j" % "barcode4j" % "2.0", 
    "postgresql" % "postgresql" % "9.1-901.jdbc4" 
)

您可以连接到本地postgresql而无需用户名/密码吗？ （使用'psql'，每个实例）。 – marcospereira

如果您正在使用更新版本的PostgreSQL，您可能需要使用驱动程序的更新版本：

libraryDependencies += "org.postgresql" % "postgresql" % "9.4.1208"
