Convert any Scala object to JSON
Given that there is only a limited number of types you want to serialize to JSON, this should work:
object MyWriter { implicit val anyValWriter = Writes[Any] (a => a match { case v:String => Json.toJson(v) case v:Int => Json.toJson(v) case v:Any => Json.toJson(v.toString) // or, if you don't care about the value case _ => throw new RuntimeException("unserializeable type") })}
You can use it by then by importing the implicit value at the point where you want to serialize your Any
:
import MyWriter.anyValWriterval a: Any = "Foo"Json.toJson(a)
Using json4s, you can import the package:
import org.json4s.DefaultFormatsimport org.json4s.native.Serialization.write
Then create an implicit variable inside your trait:
implicit val formats: DefaultFormats = DefaultFormats
And finally, in your method, use it:
write(myObject)
