同学你好，老师运行代码，报错信息是Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'.

加载类“com.mysql.jdbc.Driver”。这是弃用。新的驱动程序类是' com.mysql.cj.jdbc.Driver'。

如上所示内容可知，新的驱动是com.mysql.cj.jdbc.Driver，同学的mysql版本是8吧，如果是，同学可以修改注册驱动为com.mysql.cj.jdbc.Driver ，修改后再来尝试一下。

老师测试修改后可正常运行并显示数据

如果同学运行还有别的错误，建议同学将报错信息贴出

如果我的回答解决了你的疑惑，请采纳。祝：学习愉快~
