JSON to Groovy parser

Question

I found many things about converting Groovy to JSON, but oddly enough, not the other way.

What is the (best) JSON to Groovy parser around there ?

Answer 1

If you are on Groovy 1.8 or later, there is a build in JsonSlurper you can use this way:

import groovy.json.JsonSlurper  //Attention: you have to use double quotes inside the json string def jsonObj = new JsonSlurper().parseText( '{ "name":"Peter", "age": 23}' )  assert jsonObj.name == "Peter" assert jsonObj.age == 23 //this won't work, because it's not defined assert jsonObj.gender == null
