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

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'
