//JsonOutputのサンプル

//サンプルデータ
def data = {
  people {
    person {
      firstName 'Yasuharu'
      lastName 'Hayami'
      // Named arguments are valid values for objects too
      address(
        city: 'Niigata',
        country: 'Japan',
        zip: 9501115
      )
      married false
      // a list of values
      conferences 'JGGUG', 'JJUG'
    }
  }
}

//JsonOutput.toJson()の例
def resultJsonOutput1 = JsonOutput.toJson data
println resultJsonOutput1
//JsonBuilderで書くとこうなる
def builder = new JsonBuilder()
builder data
def resultJsonBuilder1 = builder.toString()
println resultJsonBuilder1
//結果は一緒
assert resultJsonOutput1 == resultJsonBuilder1

//JsonOutput.prettyPrint()の例
def resultJsonOutput2 = JsonOutput.prettyPrint resultJsonOutput1
println resultJsonOutput2
//JsonBuilderで書くとこうなる
def resultJsonBuilder2 = builder.toPrettyString()
println resultJsonBuilder2 
//結果は一緒
assert resultJsonOutput2 == resultJsonBuilder2
