如何在Android中使用Retrofit和Gson解析嵌套的JSON数据

implementation 'com.squareup.retrofit2:retrofit:2.x.x'
implementation 'com.squareup.retrofit2:converter-gson:2.x.x'

{
  "name": "John",
  "age": 25,
  "address": {
    "street": "123 Main St",
    "city": "New York"
  }
}

public class User {
    private String name;
    private int age;
    private Address address;

    // Getters and setters
}

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

    // Getters and setters
}

public interface ApiService {
    @GET("user")
    Call<User> getUser();
}

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("https://api.example.com/")
    .addConverterFactory(GsonConverterFactory.create())
    .build();

ApiService apiService = retrofit.create(ApiService.class);

apiService.getUser().enqueue(new Callback<User>() {
    @Override
    public void onResponse(Call<User> call, Response<User> response) {
        if (response.isSuccessful()) {
            User user = response.body();
            // 使用解析后的数据进行操作
        } else {
            // 请求失败处理
        }
    }

    @Override
    public void onFailure(Call<User> call, Throwable t) {
        // 请求失败处理
    }
});
