JSON

class Person {
    String name
    Integer age
}

//对象转成json字符串
def list=[new Person(name:'jett',age:18),
            new Person(name:'lance',age:18)]
println JsonOutput.toJson(list)
//对象转成json字符串: 格式化
def json=JsonOutput.toJson(list)
println JsonOutput.prettyPrint(json)

//json字符串转成对象
def jsonSluper=new JsonSlurper()
def object=jsonSluper.parse("[{\"age\":18,\"name\":\"jett\"},{\"age\":18,\"name\":\"lance\"}]".getBytes())
println object

def object2=jsonSluper.parse("[{\"abc\":\"jett\"}]".getBytes())
println object2.abc

XML
