  private void parseJson(){
    File jsonFile = ResourceUtils.getFile("classpath:serviceConfig.json");
    String json = FileUtils.readFileToString(jsonFile);
    JSONArray jsonArray = JSON.parseArray(json);
    for (Object obj : jsonArray) {
        JSONObject jobj = (JSONObject) obj;
        String iso = jobj.getString("***");
    }
  }

方式二：

  @Value("classpath:serviceConfig.json")
  private Resource resource;
  private void parseJson(){
     File file = areaRes.getFile();
     String jsonData = this.jsonFileReader(file);
     JSONObject jsonObject = JSONObject.parseObject(jsonData);
     .....
  }
  private String jsonFileReader(File file){
      Scanner scanner = null;
      StringBuilder buffer = new StringBuilder();
      try {
          scanner = new Scanner(file, "utf-8");
          while (scanner.hasNextLine()) {
              buffer.append(scanner.nextLine());
          }
      } catch (Exception e) {
           e.printStackTrace();
      } finally {
          if (scanner != null) {
              scanner.close();
          }
      }
      return buffer.toString();
  }
