Loading class `com.mysql.jdbc.Dr

Loading class com.mysql.jdbc.Driver'. This is deprecated. The new driver class iscom.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.
mybatis逆向过程中出现的 ,用了最新的mysql 连接驱动

jdbc.driverClass   = com.mysql.dbc.Driver
jdbc.url = jdbc:mysql://127.0.0.1:3306/db?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT
jdbc.username = root
jdbc.password = root123

现在按照最新官方提示支持将com.mysql.jdbc.Driver 改为 com.mysql.cj.jdbc.Driver

jdbc.url = jdbc:mysql://127.0.0.1:3306/db?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT
jdbc.username = root
jdbc.password = root123
