描述：
未能配置DataSource：未指定"url"特性，也无法配置任何嵌入的数据源。
原因：无法确定合适的驱动程序类别
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).
Process finished with exit code 1
在application.properties中，需要用spring.datasource命名数据源属性。即
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=admin
您可以在此处查看常用数据属性。
