Easily serialise any object to JSON in Scala via an implicit conversion.

JsonOps.scala

/*
 * Usage:
 *   
 *   import com.ben2.jsonops.Implicits._
 *   val obj = makeSomeObject()
 *   println(obj.toJson)
 */

package com.ben2.jsonops

import com.fasterxml.jackson.databind.{Module, ObjectMapper, SerializationFeature}
import com.fasterxml.jackson.module.scala.DefaultScalaModule

// render arbitrary objects to JSON using Jackson
class JsonOps(val obj: Any) {
  def mapper = {
    val mapper = new ObjectMapper()
    mapper.registerModule(DefaultScalaModule)
    mapper
  }

  def toJson: String = mapper.writeValueAsString(obj)
}

object Implicits {
  implicit def anyToJsonOps(obj: Any): JsonOps = new JsonOps(obj)
}
