SpringBoot中如何解决读取properties文件读取问题

public static void main(String[] args) throws IOException {
        Properties properties = new Properties();
        ClassPathResource classPathResource = new ClassPathResource("ProducerQuickStart.properties");
        InputStream inputStream = classPathResource.getInputStream();
        InputStreamReader inputStreamReader = new InputStreamReader(inputStream,"utf-8");
        BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
        properties.load(bufferedReader);
        Set<Object> keySets = properties.keySet();
        Iterator<Object> iterator = keySets.iterator();
        while (iterator.hasNext()){
            Object obj = iterator.next();
            System.out.println("键："+obj+"   值："+properties.get(obj));
        }
    }

validity.of.captcha=120
