Spring Boot 读取静态文件

     try {
            Resource resource = new ClassPathResource("area-code/relayNumber.json");
            reader = new BufferedReader(new InputStreamReader(resource.getInputStream()));
            //每次读取文件的缓存
            String temp = null;
            while ((temp = reader.readLine()) != null) {
                data.append(temp);
            }
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            //关闭文件流
            if (reader != null) {
                try {
                    reader.close();
                } catch (IOException e) {

                }
            }
        }
        String str = data.toString();
