成功解决The new driver class is `com.mysql.cj.jdbc.Driver'

SpringBoot +MyBatis自动生成mapper层代码时，报错：

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.

解决方法：将加载数据库驱动的语句更改 com.mysql.cj.jdbc.Driver
