在groovy1.8中内置了对json格式数据的至此；
使对json的操作变得非常简捷方便了

Java代码 
def builder = new JsonBuilder() 
//如同构建对象般 
builder.pepole{ 
    person { 
        firstName 'leng' 
        lastName 'feng' 
        //传入map 
        address( 
                city: 'Shanghai', 
                country: 'China', 
                zip: 12345, 
                ) 
        married true 
        //传如list 
        conferences 'JavaOne', 'Gr8conf' 
    } 
} 
//以树形结构输出 
println JsonOutput.prettyPrint(builder.toString()) 
 
 
String json = """ 
{ 
    "pepole": { 
        "person": { 
            "firstName": "leng", 
            "lastName": "feng", 
            "address": { 
                "city": "Shanghai", 
                "country": "China", 
                "zip": 12345 
            }, 
            "married": true, 
            "conferences": [ 
                "JavaOne", 
                "Gr8conf" 
            ] 
        } 
    } 
} 
""" 
//类似XmlSlurper 
def root = new JsonSlurper().parseText(json) 
assert root instanceof Map 
assert root.person.conferences instanceof List 
assert root.person.firtsName == 'leng' 
assert root.person.conferences[1] == 'Gr8conf'
