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

异常错误：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.

这个问题 是在我整合项目过程中出现的，用了最新的mysql 连接驱动

以前版本的jdbc.properties

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.driverClass = 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

这个是因为用的最新的数据库驱动的原因，用较早的版本就可以了。
