错误：

Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver 
class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via 
the SPI and manual loading of the driver class is generally unnecessary.

虽然结果运行没问题，但一开始就报这么一个错看着也不舒服。
后来发现原来新版的连接MySQL驱动包的driver改了。
旧版：

新版：
