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

Question

***************************
APPLICATION FAILED TO START
***************************
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).
I have tried using
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5InnoDBDialect
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
in application properties but still it didn't work.
And even in have tried using
#SpringBootApplication(exclude = {DataSourceAutoConfiguration.class }) or
#EnableAutoConfiguration (exclude = {DataSourceAutoConfiguration.class })
then im not gettin any error but the table is getting created in the database.
