Groovy - Convert object to JSON string

Question

I'm pretty used to Grails converters, where you can convert any object to a JSON representation just like this (http://grails.org/Converters+Reference)

return foo as JSON 

But in plain groovy, I cannot find an easy way to do this (http://groovy-lang.org/json.html)

JSONObject.fromObject(this) 

return empty json strings...

Am I missing an obvious Groovy converter ? Or should I go for jackson or gson library ?

Answer 1

Do you mean like:

import groovy.json.*  class Me {     String name }  def o = new Me( name: 'tim' )  println new JsonBuilder( o ).toPrettyString() 

Answer 2

I couldn't get the other answers to work within the evaluate console in Intellij so...

groovy.json.JsonOutput.toJson(myObject) 

This works quite well, but unfortunately

groovy.json.JsonOutput.prettyString(myObject) 

didn't work for me.

To get it pretty printed I had to do this...

groovy.json.JsonOutput.prettyPrint(groovy.json.JsonOutput.toJson(myObject))
