我继续得到这个错误，任何人都可以告诉我为什么会出现这个错误或者如何解决它，它非常肯定它的数据库连接错误，在我做了一些搜索后，我发现他们改变了mysql-connector类名称：com.mysql.jdbc.Driver到com.mysql.cj.jdbc.Driver，但我仍在使用旧连接器，所以为什么我一直收到此错误。

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.
