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

问题：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.

 解决方案一：

我们可以找到resources中的yml或者是properties文件。

将com.mysql.jdbc.Driver改成com.mysql.cj.jdbc.Driver

mysql5及之前的版本使用的是旧版驱动com.mysql.jdbc.Driver

mysql6以及之后的版本需要更新到新版驱动，对应的Driver是com.mysql.cj.jdbc.Driver

解决方案二：

或者我们找到xml文件中的mysql将它的版本提高一些即可。
