如何将 `org.codehaus.jettison.json.JSONObject` 转换为 `org.json.JSONObject`
     import org.codehaus.jettison.json.JSONObject;
        ....
        ....
        JSONObject rawSchema = ExportUtil.getFileAndConvertToJson(environment.getProperty("export.path")+ "schema.json");  
        org.json.JSONObject rawSchema1 = rawSchema; // 异常：类型不匹配：无法从org.codehaus.jettison.json.JSONObject转换为org.json.JSONObject
------
    public static JSONObject getFileAndConvertToJson(String filePath) {
        File fileToDownload = new File(filePath);
        JSONObject jsonObject = null;
        try (InputStream inputStream = new FileInputStream(fileToDownload)) {
            BufferedReader streamReader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"));
            StringBuilder responseStrBuilder = new StringBuilder();
            String inputStr;
            while ((inputStr = streamReader.readLine()) != null)
                responseStrBuilder.append(inputStr);
            jsonObject = new JSONObject(responseStrBuilder.toString());
            
        } catch (Exception e) {
             
            e.printStackTrace();
        }
        return jsonObject;
    }
