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.

解释：

这个地址过期了，现在有了新的地址

解决：

配置文件中，关于数据库配置的驱动已过期，

driver-class-name: com.mysql.jdbc.Driver 改为 driver-class-name: com.mysql.cj.jdbc.Driver
