Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdb

启动springboot的时候，日志显示错误

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.

按照提示信息将配置文件中的驱动类修改为
com.mysql.cj.jdbc.Driver

重新启动，就ok了。

原因：
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’
