How to deserialize a json file to Map[String,String] in scala? #64

It works fine for me in java where as in scala i am getting the below exception. Please let me know how can i resolve this?

val jsonContent ="""{"test":"113123","myList":{"test2":"321323"}}"""
val mapData = mapper.readValue(jsonContent, classOf[Map[String,String]])

Error:

com.fasterxml.jackson.databind.JsonMappingException: Can not construct instance of scala.collection.immutable.Map, problem: abstract types either need to be mapped to concrete types, have custom deserializer, or be instantiated with additional type information
