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

遇到如下问题：

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.

mysql-connector-java包版本问题：

5.x版本的驱动文件jar包对应的是：Class.forName(“com.mysql.jdbc.Driver”);语句来加载数据库驱动

8.0x版本的驱动文件jar包对应的是Class.forName(“com.mysql.cj.jdbc.Driver”);

查看你所使用的jdbc驱动，修改就好。
