APPLICATION FAILED TO START

Description:

Cannot determine embedded database driver class for database type NONE

Action:

If you want an embedded database please put a supported one on the classpath. If you have database settings to be loaded from a particular profile you may need to active it (no profiles are currently active).

The reason is: when springboot starts, it will automatically inject data source and configure JPA
solution: exclude its injection in @ springbootapplication
@ springbootapplication (exclude = {datasourceautoconfiguration. Class, hibernatejpaautoconfiguration. Class})

//@SpringBootApplication
@SpringBootApplication(exclude={DataSourceAutoConfiguration.class,HibernateJpaAutoConfiguration.class})
public class CreditApplication {
    public static void main(String[] args) {
        SpringApplication.run(CreditApplication.class, args);
    }
}

Add the above configuration.
