使用Gson反序列化复杂的JSON (多个嵌套元素)

Gson gson = new Gson();

{
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York"
  },
  "phoneNumbers": [
    "123-456-7890",
    "987-654-3210"
  ]
}

public class Person {
  private String name;
  private int age;
  private Address address;
  private List<String> phoneNumbers;

  // getters and setters
}

public class Address {
  private String street;
  private String city;

  // getters and setters
}

String json = "{\"name\":\"John\",\"age\":30,\"address\":{\"street\":\"123 Main St\",\"city\":\"New York\"},\"phoneNumbers\":[\"123-456-7890\",\"987-654-3210\"]}";

Person person = gson.fromJson(json, Person.class);

String name = person.getName();
int age = person.getAge();
String street = person.getAddress().getStreet();
String city = person.getAddress().getCity();
List<String> phoneNumbers = person.getPhoneNumbers();
