How to add QueryHints on Default Spring Data JPA Methods?

Question

I am able to use Query Cache with Spring Data JPA for my custom query methods like below.

public interface CountryRepository extends JpaRepository<Country, String> {
@QueryHints({ @QueryHint(name = "org.hibernate.cacheable", value ="true") })
Country findByCountryName(String countryName);
@QueryHints({ @QueryHint(name = "org.hibernate.cacheable", value ="true") })
Country findByCountryCode(String countryCode); }

However, how to add @QueryHints on existing parent methods like findAll()?

Thanks.

Answer 1

findAll(), findOne() etc. are not Query(s). Any caching specifications on the entity take effect in these methods.

For example,

@Cacheable
@Entity
public class User {

}

Answer 2

Originally, there was no support for query hint annotations in default CRUD methods, but apparently it hass been fixed for version 1.6M1:
