如何使用asynctask json做pojo

public class MyAsyncTask extends AsyncTask<Void, Void, MyPojo> {

    private static final String JSON_URL = "http://example.com/data.json";

    @Override
    protected MyPojo doInBackground(Void... voids) {
        try {
            // 发送HTTP请求获取JSON数据
            URL url = new URL(JSON_URL);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("GET");

            // 解析JSON数据
            InputStream inputStream = connection.getInputStream();
            BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
            StringBuilder stringBuilder = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                stringBuilder.append(line);
            }
            reader.close();
            inputStream.close();
            String json = stringBuilder.toString();

            // 将JSON数据转换为POJO对象
            Gson gson = new Gson();
            MyPojo myPojo = gson.fromJson(json, MyPojo.class);

            return myPojo;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(MyPojo myPojo) {
        if (myPojo != null) {
            // 更新UI界面，显示POJO对象的数据
            // 例如，可以将数据显示在TextView中
            textView.setText(myPojo.getName());
        }
    }
}
