Loading class com.mysql.jdbc.Driver'. This is deprecated. The new driver class iscom.mysql.cj.jdbc.Driver’. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

搭建springboot2.27，我默认集成了mysql连接依赖，结果报了上面的异常。

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

这是由于依赖的mysql的版本太高导致。springboot2.27默认依赖的版本如下图：

		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
			<!--<version>5.1.47</version>
		</dependency>

然后就解决了。
