JDBC连接数据库报错：Loading class `com.mysql.jdbc.Driver'. This is deprecated.

使用JDBC连接数据库时出现报错，

报错内容：
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. 

解决办法：
将com.mysql.jdbc.Driver  改为  com.mysql.cj.jdbc.Driver即可。

<property name="driver" value="com.mysql.cj.jdbc.Driver" />
