Groovy是一種強類型的動態語言，具有簡單易學、能夠以面向對象和函數式編程模式進行編程等特點，在大數據領域、Web應用程序開發、測試自動化領域、DevOps等方面有著廣泛的應用。其中在Json處理方面，Groovy也有著較為方便的處理方式。

Groovy語言內置了對Json字符串處理的支持，可以在Json與JavaBean對象、Map之間進行相互轉換，通過使用JsonBuilder和JsonSlurper類，可以很輕松地構建和解析Json數據。

//構建Json字符串
def builder = new JsonBuilder()
def person = builder{
name "Tom"
age 20
address{
city "Beijing"
zip 100001
}
}
assert person.toString() == '{"name":"Tom","age":20,"address":{"city":"Beijing","zip":100001}}'
//解析Json字符串
def slurper = new JsonSlurper()
def json = '{"name":"Tom","age":20,"address":{"city":"Beijing","zip":100001}}'
def person = slurper.parseText(json)
assert person.name == "Tom"
assert person.address.city == "Beijing"

此外，Groovy還提供了JsonOutput和JsonParser類快速將JavaBean對象或Map轉換成Json字符串，方便數據的傳輸和存儲。

//將JavaBean對象轉換成Json字符串
class Person{
String name
int age
String city
}
def person = new Person("Tom", 20, "Beijing")
def json = JsonOutput.toJson(person)
assert json == '{"name":"Tom","age":20,"city":"Beijing"}'
//將Map轉換成Json字符串
def map = [name:"Tom", age:20, address:[city:"Beijing", zip:100001]]
def json = JsonOutput.toJson(map)
assert json == '{"name":"Tom","age":20,"address":{"city":"Beijing","zip":100001}}'
//將Json字符串轉換成JavaBean對象
def json = '{"name":"Tom","age":20,"city":"Beijing"}'
def person = JsonParser.parseJson(json, Person)
assert person.name == "Tom"
assert person.age == 20
assert person.city == "Beijing"

通過使用上述方法，Groovy可以輕松地處理Json數據，提高開發效率。
