Example
import groovy.json.JsonOutput;
def json = JsonOutput.toJson([foo: 'bar', baz: [1]])
assert json == '{"foo":"bar","baz":[1]}'
In addition to maps, lists and primitives groovy.json.JsonOutput also supports a POJOs serialitzation:
import groovy.json.JsonOutput;
class Tree {
def name
def type
}
Tree willow = new Tree(name:'Willow',type:'Deciduous')
Tree olive = new Tree(name:'Olive',type:'Evergreen')
assert JsonOutput.toJson(willow) == '{"type":"Deciduous","name":"Willow"}'
assert JsonOutput.toJson([willow,olive]) == '[{"type":"Deciduous","name":"Willow"},{"type":"Evergreen","name":"Olive"}]'
