Groovy操作json

groovy 1.8にはjson形式のデータが内蔵されている.
jsonの操作を非常に簡素で便利にしました

def builder = new JsonBuilder()
//       
builder.pepole{
	person {
		firstName 'leng'
		lastName 'feng'
		//  map
		address(
				city: 'Shanghai',
				country: 'China',
				zip: 12345,
				)
		married true
		//  list
		conferences 'JavaOne', 'Gr8conf'
	}
}
//       
println JsonOutput.prettyPrint(builder.toString())




String json = """

    "pepole": {
