실무 활용 - 스프링 데이터 JPA와 Querydsl

스프링 데이터 JPA 리포지토리로 변경

 

스프링 데이터 JPA - MemberRepository 생성

public interface MemberRepository extends JpaRepository<Member, Long> {

    List<Member> findByUsername(String username);
}

 

스프링 데이터 JPA 테스트

@SpringBootTest
@Transactional
class MemberRepositoryTest {

    @Autowired
    EntityManager em;

    @Autowired
    MemberRepository memberRepository;

    @Test
    public void basicTest() {
        Member member = new Member("member1", 10);
        memberRepository.save(member);
        Member findMember = memberRepository.findById(member.getId()).get();
        assertThat(findMember).isEqualTo(member);



        List<Member> result1 = memberRepository.findAll();
        assertThat(result1).containsExactly(member);


        List<Member> result2 = memberRepository.findByUsername("member1");
        assertThat(result2).containsExactly(member);

    }
}

Querydsl 전용 기능인 회원 search를 작성할 수 없다. 사용자 정의 리포지토리 필요
