java - JSON 字符串到 Object[]

Question

我需要将 JSON 字符串转换为 Object[]。

我尝试过 link1和 link2并没有帮助我。

编写如何获取 JSON 字符串的代码:

public static String getListJsonString() {
    String getListsUrl = BASE_URL + "lists";
    String result = "";
    try {
        URL url = new URL(getListsUrl);
        URLConnection urlConnection = url.openConnection();
        urlConnection.setRequestProperty("Authorization", "Basic " + getAuthStringEnc());
        InputStream is = urlConnection.getInputStream();
        InputStreamReader isr = new InputStreamReader(is);

        int numCharsRead;
        char[] charArray = new char[1024];
        StringBuffer sb = new StringBuffer();
        while ((numCharsRead = isr.read(charArray)) > 0) {
            sb.append(charArray, 0, numCharsRead);
        }
        result = sb.toString();
        System.out.println(result);
    } catch (Exception e) {
        e.printStackTrace();
    }

    return result;
}

这是我的 JSON 示例:

之后我必须以这种方式填充 ChomboBox(这是示例):

Object[] lists = getLists();
for(Object list : lists){
    System.out.println("fill combobox");
}

您可以使用Gson、TypeToken和JSONObject，例如:

final static Gson gson = new GsonBuilder().excludeFieldsWithoutExposeAnnotation().create();
final Type objectType = new TypeToken<Object>(){}.getType();

JSONObject obj = new JSONObject(result);

Vector<Object> lists = gson.fromJson(obj.toString(), objectType);
