Auto-detection of Hibernate and Spring Data JPA:

💡 Perhaps you are facing an N+1 select issue
	* With Hibernate, you may fix it by using JOIN FETCH
	                                       or LEFT JOIN FETCH
	                                       or FetchType.LAZY
	                                       or ...

	* With Spring Data JPA, you may fix it by adding @EntityGraph(attributePaths = { "..." })
      	  on repository method: https://docs.spring.io/spring-data/jpa/docs/current/reference/ht
