读取本地json文件并解析

  1. StringBuilder result = new StringBuilder();
  2. try (FileInputStream fileInputStream = new FileInputStream("本地json文件全路径");
  3.      InputStreamReader inputStreamReader = new InputStreamReader(fileInputStream, StandardCharsets.UTF_8);
  4.      BufferedReader reader = new BufferedReader(inputStreamReader);) {
  5.     String tempString = null;
  6.     while ((tempString = reader.readLine()) != null) {
  7.         result.append(tempString);
  8.     }
  9. } catch (Exception e) {
  10.     e.printStackTrace();

  12. //根据具体情况转成array或者object
  13. JSONArray array = JSON.parseObject(result.toString(), JSONArray.class);
