vue cli 버전이 4이상인 경우에는 어떻게 해야될지 모르겠어요.

vue3가 기본버전으로 바뀌면서
vue transition을 구글로 검색하면 맨 첫 번째 검색결과는 3버전 문서가 나오네요
2버전은 아래 url을 참고하면 좋을것 같습니다!
https://v2.vuejs.org/v2/guide/transitions.html
https://v2.vuejs.org/v2/guide/transitions.html#List-Entering-Leaving-Transitions

transition enter

요기 참고해도 좋겟네요!

scf 작동이 안됩니다.

아 답변감사합니다. jpql을 사용한다니 신기하네요.
궁금한게 있는데요 기선님은 저런내용을 어떻게 아시는거에요? jpa도큐먼트를 보면 나오나요??
혹시 url이있다면 좀 알려주실수 있을까요 ㅎ
저도 나중에 궁금하거나 이해안되는 부분이 있으면 스스로 답을 찾고싶어서 여쭤봅니다 :)

그리고 유투브를 통해 새로운 강의가 나온다고 들었습니다. 기대되네요~ㅎㅎ

findAll() 메서드

네 답변 주셔서 감사합니다.
먼저 기분나쁘셨다면 사과드릴게요ㅠㅠ 그리고 이 질문이&nbsp;<a href="https://www.inflearn.com/course/%EC%8A%A4%ED%94%84%EB%A7%81-%EB%8D%B0%EC%9D%B4%ED%84%B0-jpa/lecture/13775" target="_blank" rel="noopener noreferrer">스프링 데이터 JPA 2. JpaRepository.save() 메소드 </a>이 강의에 되어있는지 잘 모르겠네요 다른데서 질문을 남긴것 같은데ㅠㅠ
아마 스프링 데이터 JPA 7.EntityGraph 강의에 질문을 남겼던것 같습니다... 이 강의의 질문에 보면 3개중에 2개가 답변이 없어서 답변이 잘 안 달리나보다 생각했습니다ㅠㅠ
좋은강의 잘듣고 있어서 감사한데 기분나쁘게 해서 죄송해여ㅠㅠ
제가 3가지를 해봤는데요 ManyToOne으로 fetch 전략을 1)default로 한경우 2)LAZY로 한경우 3)EAGER로 한경우로 해봤습니다.
1)fetch전략을 default로 한경우
&nbsp;- findAll() : lazy로 동작,&nbsp; findById() : EAGER로 동작
2)fetch전략을 lazy로 한경우
&nbsp;- findAll() : lazy로 동작, findById() : lazy로 동작
3)fetch전략을 eager로 한경우
&nbsp;- findAll() : lazy로 동작, findById() : eager로 동작

아래 코드랑 결과도 작성해 드립니다..
혹시 제가 잘못 설정해서 그런것이 있다면 지적해주시고 알려주시면 감사드리겠습니다.

TestRestTemplate 으로 getForOjbect 했을경우

답변해주셔서 감사합니다.
그런데 제가 첨부한 이미지를 보시면 get("/hello") 로 문자열까지 코딩한 다음에 import 하려고 하는데 저렇게 나타나구요..
저 많은 목록중에&nbsp;<span style="background-color: #ffffff; color: #000a12; font-family: 'Spoqa Han Sans', 'Apple SD Gothic Neo', system-ui, -apple-system, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Fira Sans', 'Droid Sans', 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 16px;">MockMvcRequestBuilders.get 을 찾아도 없더라구요..ㅠㅠ
