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.

处理方法：提示信息表明数据库驱动com.mysql.jdbc.Driver'已经被弃用了、应当使用新的驱动com.mysql.cj.jdbc.Driver'

所以，按照提示更改jdbc.properties配置 .com.mysql.jdbc.Driver  改为  com.mysql.cj.jdbc.Driver
