SpringBoot项目启动报错Failed to determine a suitable driver class

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
	If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
	If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

Disconnected from the target VM, address: '127.0.0.1:51507', transport: 'socket'

Process finished with exit code 0

说明：配置数据源失败：未指定“url”属性，无法配置嵌入式数据源。
原因：无法确定合适的驱动程序类别
行动：考虑以下事项：
如果您想要一个嵌入式数据库（H2、HSQL或Derby），请将其放在类路径上。
如果要从特定配置文件加载数据库设置，则可能需要激活它（当前没有激活的配置文件）。

经过测试，我把pom.xml文件里的mysql、mybatis注释掉之后，就可以运行啦
