使用Groovy解析嵌套Json中的值

@Grab('org.codehaus.groovy:groovy-json:3.0.0')
import groovy.json.JsonSlurper

def jsonStr = '''
{
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York"
  },
  "hobbies": ["reading", "music", "sports"]
}
'''

def jsonSlurper = new JsonSlurper()
def json = jsonSlurper.parseText(jsonStr)

def name = json.name
def age = json.age
def street = json.address.street
def city = json.address.city
def hobbies = json.hobbies

println "Name: $name"
println "Age: $age"
println "Street: $street"
println "City: $city"
println "Hobbies: $hobbies"

Name: John
Age: 30
Street: 123 Main St
City: New York
Hobbies: [reading, music, sports]
