Scala: convert map to case class

Question

Let\'s say I have this example case class

case class Test(key1: Int, key2: String, key3: String)

And I have a map

myMap = M         


        

Answer 1

This works well for me，if you use jackson for scala：

def from[T](map: Map[String, Any])(implicit m: Manifest[T]): T = {
  val mapper = new ObjectMapper() with ScalaObjectMapper
  mapper.convertValue(map)
}
