This seems to work-
val printEntry = new
java.util.function.Consumer[java.util.Map.Entry[String,com.typesafe.config.ConfigValue]]
{
override def accept(a:
java.util.Map.Entry[String,com.typesafe.config.ConfigValue]): Unit = {
println(a.getKey)
}
}
conf.entrySet.iterator.forEachRemaining (printEntry)
// returns
scala> conf.entrySet.iterator.forEachRemaining (printEntry)
dbUsername
dbPassword
bootstrapServers
dbDatabase
I hope that helps.
