Answer

It seems that you failed to provide driver-class name.

spring.datasource.url=jdbc:mysql://localhost:3306/mlab
spring.datasource.username=root
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

You can refer to : https://www.baeldung.com/spring-boot-failed-to-configure-data-source

It should be work after adding the above mentioned properties.
