ㅇ 원인
ItemEntity 클래스 설계 시 item entity의 table 이름을 “item”으로 지정해 놈
@Query-nativeQuery는 SQL을 그대로 사용하기 때문에 table 이름을 지정해 논 item으로 써야지 올바르게 동작하는 것 같다. 따라서 itemEntity라는 클래스 이름을 썼기 때문에 itemEntity라는 테이블이름을 찾을 수 없다는 Table "ITEMENTITY" not found; SQL statement: 오류 발생
* @Query 사용시에는 itemEntity로도 제대로 동작함
ItemEntity 클래스
@Data
@Table(name="item")
@Entity
public class ItemEntity {
@Id
@Column(name="item_id")
@GeneratedValue(strategy = GenerationType.AUTO) // 기본키 생성전략 설정 : GenerationType.AUTO (JPA가 IDENTITY, SEQUENCE, TABLE 중 자동 선택)
private Long itemId; // 상품 코드
. . .
@Column(name = "update_time", nullable = false)
private LocalDateTime updateTime; // 수정 시간
}→ ItemEntity 설계시 @Table(name="item) 을 통해 테이블 명을 item으로 지정
ItemRepository 인터페이스
public interface ItemRepository extends JpaRepository<ItemEntity, Long> {
// #2 @Query 어노테이션 실습
// @Query 상품 데이터 조회 실습
@Query("select i from ItemEntity i where i.itemDetail like %:itemDetail% " +
"order by i.price desc")
List<ItemEntity> findByItemDetail(@Param("itemDetail") String itemDetail);
// @Query-nativeQuery를 이용한 상품 조회 실습
// nativeQuery : 기존의 데이터베이스에서 사용하던 쿼리를 그대로 사용해야 할 때 사용
// But, 특정 데이터베이스에 종속됨
@Query(value = "select * from item i where i.item_detail like %:itemDetail% " +
"order by i.price desc", nativeQuery = true)
List<ItemEntity> findByItemDetailByNative(@Param("itemDetail") String itemDetail);
}→ @Query-nativeQuery를 이용한 상품 조회 시 @Query의 value 속성에 위에서 지정한 테이블 이름인 item이 아니라 itemEntity를 넣어서 오류 발생
ItemRepositoryTest
@SpringBootTest // 통합 테스트를 위해 스프링 부트에서 제공하는 어노테이션, 실제 어플리케이션을 구동할 때처럼 모든 Bean을 IoC 컨테이너에 등록
@TestPropertySource(locations="classpath:application-test.properties") // 설정 파일 application-test.properties에 우선순위 부여 : Test DB로 H2를 사용
class ItemRepositoryTest {
@Autowired // itemRepository를 사용하기 위하여 @Autowired 어노테이션을 이용하여 Bean 주입
ItemRepository itemRepository;
@Test // 테스트할 대상 지정 : 테스트할 메소드 위에 선언
@DisplayName("상품 저장 테스트") // Junit5에 추가된 어노테이션으로 테스트 코드 실행 시 @DisplayName에 지정한 테스트명 노출
public void createItemTest() {
for(int i=1; i<=10; i++) {
ItemEntity item = new ItemEntity();
item.setItemName("테스트 상품"+ i );
item.setPrice(10000+ i);
item.setStockNumber(100 - i);
item.setItemDetail("테스트 상품 상세 설명" + i);
item.setItemSellStatus(ItemSellStatus.SELL);
item.setRegTime(LocalDateTime.now());
item.setUpdateTime(LocalDateTime.now());
ItemEntity savedItem = itemRepository.save(item); // itemRepository가 상속받은 JpaRepository(CrudRepository) 인터페이스의 save 메소드 동작
System.out.println(savedItem.toString());
}
}
// #2 @Query 테스트
// @Query를 이용한 상품 조회 테스트
@Test
@DisplayName("@Query를 이용한 상품 조회 테스트")
public void findByItemDetailTest(){
this.createItemTest(); // 10개의 상품 저장하는 테스트코드 실행
List<ItemEntity> itemList = itemRepository.findByItemDetail("테스트 상품 상세 설명");
System.out.println("Test");
for(ItemEntity itemEntity : itemList) {
System.out.println(itemEntity.toString());
}
}
// @Query-nativeQuery를 이용한 상품 조회 테스트
@Test
@DisplayName("@Query-nativeQuery를 이용한 상품 조회 테스트")
public void findByItemDetailByNativeTest(){
this.createItemTest(); // 10개의 상품 저장하는 테스트코드 실행
List<ItemEntity> itemList = itemRepository.findByItemDetailByNative("테스트 상품 상세 설명");
System.out.println("Test");
for(ItemEntity itemEntity : itemList) {
System.out.println(itemEntity.toString());
}
}
}
ㅇ 해결방법
ItemRepository.java 파일에서 @Query 속성 아래와 같이 수정
@Query(value = "select * from itemEntity i where i.item_detail like %:itemDetail% order by i.price desc", nativeQuery = true) →
@Query(value = "select * from item i where i.item_detail like %:itemDetail% order by i.price desc", nativeQuery = true)
