import jakarta.persistence.EntityManager;
import lombok.RequiredArgsConstructor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
@RequiredArgsConstructor
public class QueryDSLConfig {

    private final EntityManager entityManager;

    @Bean
    public JPAQueryFactory jpaQueryFactory(){
        return new JPAQueryFactory(entityManager);
        // private final JPAQueryFactory queryFactory;
    }
}
