阅读Play for Scala中的application.conf配置

Question

I have the following data source configured in application.conf that I use to run Slick statements.

I need to access the same database through an OLAP engine that will use the same user and password.

Since it's already configured, I'd like to get these two from there, is it possible to read application.conf from Scala? I know I can read the physical file, but is there a library to get the parsed data?

## JDBC Datasource

dbConfig = {
  url = "jdbc:mysql://localhost:3306/db"
  driver = com.mysql.jdbc.Driver
  connectionPool = disabled
  keepAliveConnection = true
  user=root
  password=xxxx
}

Answer 1

Working with play, you simply inject the configuration like this:

import javax.inject.Inject
import play.api.Configuration

class Something @Inject()(configuration: Configuration) {
  val url: Option[String] = configuration.getString("dbConfig.url")
  val keepAliveConnection: Option[Boolean] = configuration.getBoolean("dbConfig.keepAliveConnection")

  ...
}

Also see Configuration API on how to get your properties in various types and formats.
