Check for following points.

1. The entity class package should be subclass of main class package annotated with @SpringBootApplication.

2. Otherwise use @EntityScan with @SpringBootApplication annotation to specify entity class package.

3. Annotate @EnableJpaRepositories with @SpringBootApplication because you are using CrudRepository.
