无法使用 Play-2.6 和 Quill.io 为配置加载数据源

Question

我目前在尝试运行我的 Play 应用程序时遇到错误。它说 Failed to load data source 但它看起来确实正在加载数据源。我是 Play 和 Scala 的新手，我团队的其他成员也是新手，如果这是一个愚蠢的错误或者我遗漏了一些代码示例，我深表歉意。所有者为 root 的数据库 app-users 存在于我的本地，我认为 root 没有密码（使用 createuser 工具创建）。

有什么可能导致这种情况的想法吗？或者我缺少什么？

错误：

play.api.UnexpectedException: Unexpected exception[IllegalStateException: Failed to load data source for config: 'Config(SimpleConfigObject({"dataSource":"org.postgresql.ds.PGSimpleDataSource","database":"app-users","driver":"org.postgresql.Driver","host":"localhost","password":"","port":5432,"url":"jdbc:postgresql://localhost:5432/app-users","user":"root"}))']

application.conf

play.db {
  config = "db"
  default = "default"
}

db.default {
  driver     = "org.postgresql.Driver"
  dataSource = "org.postgresql.ds.PGSimpleDataSource"
  url        = "jdbc:postgresql://localhost:5432/app-users"
  user       = "root"
  user       = ${?DB_USER}
  host       = "localhost"
  host       = ${?DB_HOST}
  port       = 5432
  port       = ${?DB_PORT}
  password   = ""
  password   = ${?DB_PASSWORD}
  database   = "app-users"
}

db/package.scala

import io.getquill.{PostgresJdbcContext, SnakeCase}

package object db {
  class DBContext(config: String) extends PostgresJdbcContext(SnakeCase, config)

  trait Repository {
    val ctx: DBContext
  }
}

使用：

Scala 2.12.4
羽毛笔 2.3.2
播放 2.6.6
Postgres JDBC 驱动程序 42.2.1
PostgreSQL 10.2

更新：为 root 用户添加了密码 "root" 并切换到使用与 Quill docs 相同的格式，所以现在 appliation.conf 看起来像这样：

db.default {
    dataSourceClassName = org.postgresql.ds.PGSimpleDataSource
    dataSource.user = root
    dataSource.password = root
    dataSource.databaseName = app-users
    dataSource.portNumber = 5432
    dataSource.serverName = host
    connectionTimeout = 30000
}

但是报错信息还是基本一样：

play.api.UnexpectedException: Unexpected exception[IllegalStateException: Failed to load data source for config: 'Config(SimpleConfigObject({"connectionTimeout":30000,"dataSource":{"databaseName":"app-users","password":"root","portNumber":5432,"serverName":"host","user":"root"},"dataSourceClassName":"org.postgresql.ds.PGSimpleDataSource"}))']

Answer 1

以下对我有用：

db.default {
    dataSourceClassName = org.postgresql.ds.PGSimpleDataSource
    dataSource.user = root
    dataSource.password = root
    dataSource.databaseName = app-users
    dataSource.portNumber = 5432
    dataSource.serverName = localhost
    connectionTimeout = 30000
}

基本上，localhost 而不是 host。我猜第一次迭代没有成功是因为引号。

无法使用 Play-2.6 和 Quill.io 为配置加载数据源
