帮助拆卸 Gson 并创建对象

我有来自服务器的 json 响应。还有加工。

问题是我无法data使用来自使用gson.

    public class Main{

    public static void main(String[] args) {

        try {
            String url = "https://ghibliapi.herokuapp.com/films";
            URL obj = new URL(url);

            HttpURLConnection connection = (HttpURLConnection) obj.openConnection();
            connection.setRequestMethod("GET");

            BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String inputLine;

            StringBuffer response = new StringBuffer();
            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
//                response.append("\n");
            }

            in.close();

//            System.out.println(response.toString().replaceAll("^.|.$", ""));
            String resString = response.toString().replaceAll("^.|.$", "");
            Gson gson = new Gson();
            String gsonString = gson.toJson(resString);
            System.out.println(gsonString);
            Data data = gson.fromJson(resString, Data.class);
            
            System.out.println(data);
//
//            String name = (String) jsonObject.get("title");
//            System.out.println(name);
//            Ghibli ghibli = new Ghibli();
//            ghibli.startApp();
        } catch (IOException ex) {
            Logger.getLogger(Ghibli.class.getName()).log(Level.SEVERE, null, ex);
        }

//     ghibli.getData("https://ghibliapi.herokuapp.com/films");
    }

}

我的数据类看起来很简单，字段和构造函数：

class Data {

private String id;
private String title;
@SerializedName("original_title")
private String mOriginal_title;
@SerializedName("original_title_romanised")
private String mOriginal_title_romanised;
private String description;
private String director;
private String producer;
@SerializedName("release_date")
private int mRelease_date;
@SerializedName("running_time")
private int mRunning_time;
@SerializedName("rt_score")
private int mRt_score;
private String[] people;
private String[] species;
private String[] locations;
private String[] vehicles;
private String[] url;

public Data(String id, String title, String mOriginal_title, String mOriginal_title_romanised, String description, String director, String producer, int mRelease_date, int mRunning_time, int mRt_score, String[] people, String[] species, String[] locations, String[] vehicles, String[] url) {
    this.id = id;
    this.title = title;
    this.mOriginal_title = mOriginal_title;
    this.mOriginal_title_romanised = mOriginal_title_romanised;
    this.description = description;
    this.director = director;
    this.producer = producer;
    this.mRelease_date = mRelease_date;
    this.mRunning_time = mRunning_time;
    this.mRt_score = mRt_score;
    this.people = people;
    this.species = species;
    this.locations = locations;
    this.vehicles = vehicles;
    this.url = url;
}
}

请求的去向（就在链接“https://ghibliapi.herokuapp.com/films”）：
