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

     整合SSM的时候运行报了一个这样的警告：

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.

原因：

jdbc.driverClassName   = com.mysql.dbc.Driverjdbc.url      = jdbc:mysql://127.0.0.1:3306/why?useUnicode=true&characterEncoding=utf8&serverTimezone=GMTjdbc.username = rootjdbc.password = 123456

最新官方提示支持将com.mysql.jdbc.Driver  改为  com.mysql.cj.jdbc.Driver
