如何将字符串从Retrofit转换为我的数据类模型中的自定义对象？

implementation 'com.google.code.gson:gson:2.8.8'

Gson gson = new GsonBuilder()
    .setLenient()
    .create();

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

public interface ApiService {
    @GET("data")
    Call<CustomDataModel> getData();
}

ApiService apiService = retrofit.create(ApiService.class);
Call<CustomDataModel> call = apiService.getData();
call.enqueue(new Callback<CustomDataModel>() {
    @Override
    public void onResponse(Call<CustomDataModel> call, Response<CustomDataModel> response) {
        if (response.isSuccessful()) {
            CustomDataModel data = response.body();
            // 在这里处理获取到的数据
        } else {
            // 处理请求失败的情况
        }
    }

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