Hello Aljoscha,
Thanks for your reply. It was really helpful.
After some time to figure out the right syntax it worked perfectly.
val user_interest = lines.map( line => {
val parsed = parse(line)
implicit lazy val formats =
org.json4s.DefaultFormats
val name =
parsed.\("name").extract[String]
val location_x =
parsed.\("location").\("x").extract[Double]
val location_y =
parsed.\("location").\("y").extract[Double]
val likes =
parsed.\("likes").extract[Seq[String]].map(_.toLowerCase()).mkString(";")
( UserInterest(name, location_x,
location_y, likes) )
})
Is this the best way to handle with json data? or is there a more
efficient way?
thank you,
norman
