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

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：
第一步，打开pom.xml，替换dependency。

替换前：
<dependency>
   <groupId>mysql</groupId>
   <artifactId>mysql-connector-java</artifactId>
   <scope>runtime</scope>
</dependency>

操作：去掉<scope>runtime</scope>这部分并且添加版本号<version>5.1.46</version>。

替换后：
<dependency>
   <groupId>mysql</groupId>
   <artifactId>mysql-connector-java</artifactId>
   <version>5.1.46</version>
</dependency>

第二步，打开application-dev.yml配置文件，更改数据库驱动。

替换前：
driver-class-name: com.mysql.cj.jdbc.Driver

操作：去掉.cj

替换后：
driver-class-name: com.mysql.jdbc.Driver

成功运行：
