新版本的logback, 如1.14.x和1.15.x对JDK的版本有要求

测试

    public static void main(String[] args) {
        Logger logger = LoggerFactory.getLogger(Log.class);
        logger.info("Hello, INFO!");
        logger.error("Hello, ERROR!");
        logger.warn("Hello, WARN!");
        System.out.println("Hello, Console!");
    }

从图中可知, out.print的信息并不会输出到FILE中, 需要额外来实现(不建议做更改, 代码上做好规范), 参考System.out.print的输出加到logback的日志文件中
