Spring Boot tries to guess the location of your @Entity definitions, based on the @EnableAutoConfiguration it finds. To get more control, you can use the @EntityScan annotation.

I used the @EntityScan annotation in the Spring main class to resolve this issue

The @ComponentScan annotation is used to automatically create beans for every class annotated with @Component, @Service, @Controller, @RestController, @Repository, ... and adds them to the Spring container (allowing them to be @Autowired).

The @EntityScan on the other hand does not create beans as far as I know. It only identifies which classes should be used by a specific persistence context.
