안녕하세요. 준호님^^
우선 확인해보니 JPA 설정들이 정상으로 되어 있지 않아서 진행이 잘 안되었더라구요.
참고로 실행하고, localhost:9080으로 접근하면 오류 로그를 볼 수 있습니다.
추가로 강의 메뉴얼에 설명드리듯이 프로젝트를 만들 때 스프링에 아직 익숙하지 않으시면 스프링 버전을 꼭! 2.1.16(2.1.x)버전을 선택해서 시작해주세요^^!
class -> enum
기존
package jpabook.jpashop.domain;
public class DeliveryStatus {
//READY, COMP
}
변경
package jpabook.jpashop.domain;
public enum DeliveryStatus {
//READY, COMP
}
class -> enum
기존
package jpabook.jpashop.domain;
public class OrderStatus {
// ORDER,CANCEL
}
변경
package jpabook.jpashop.domain;
public enum OrderStatus {
// ORDER,CANCEL
}
@OneToOne, @Enumerated(EnumType.STRING)추가
기존
public class Order {
private Delivery delivery;
private OrderStatus status; //주문상태[ORDER,CANCEL]
}
변경
public class Order {
@OneToOne
private Delivery delivery;
@Enumerated(EnumType.STRING)
private OrderStatus status; //주문상태[ORDER,CANCEL]
}
띄어쓰기 2칸 주의
