如何在使用Retrofit 2.0时将Json结果转换为Object

{
  "name": "John",
  "age": 25,
  "email": "john@example.com"
}

public class User {
    private String name;
    private int age;
    private String email;

    // 构造函数、Getter和Setter方法

    // ...
}

public interface ApiService {
    @GET("user/{id}")
    Call<User> getUser(@Path("id") int userId);
}

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("https://api.example.com/") // 替换为实际的API基础URL
    .addConverterFactory(GsonConverterFactory.create())
    .build();

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

Call<User> call = apiService.getUser(1);
call.enqueue(new Callback<User>() {
    @Override
    public void onResponse(Call<User> call, Response<User> response) {
        if (response.isSuccessful()) {
            User user = response.body();
            // 处理获取到的User对象
        } else {
            // 处理请求失败的情况
        }
    }

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