MemberServiceTest의 회원가입과 동일하게 ItemServiceTest 코드를 작성해 보았는데 다음과 같은 에러가 발생하네요... 왜 다른지 이해가 되지 않아서 질문드립니다.

강좌에서는 자바 11로 하라고 하셨는데, 혹시 자바17로 해도 되는걸까요?  Build.grade의 sourceCompatibility에 자바17버전이라고 돼있습니다. Preference의 gradle JVM은 Project SDK corretto-17 Project settings 에서 SDK는 corretto-17 Amazon Corretto version 17 입니다.  그리고 혹시 JVM에 원래 선택 돼있는  Project SDK corretto-17말고 corretto-17 Amazon Corretto version 17.0.4 도 있는데, 이걸로 바꿔야 하나도 궁금합니다.

강의에서 안내하는 bootstrap.yml을 똑같이 만들어주고 application.yml에서 아래 코드를 추가하면 됩니다. 아래서 경로 자체를 연결하는 방법도 댓글로 알려주셨는데 저는 저게 잘 안 되서 이렇게 해결했습니다. spring: config: import: - classpath:/bootstrap.yml

영상에서는 memberService 부분이 오류가 뜨는데 저는 처음 생성자를 만들 때부터 빨간 줄이 없습니다 제가 다른 부분에서 잘못 작성한게 있는건가요?

안녕하세요. 강의 수강중 intellij 버전이 달라서인지, jdk 버전이 달라서인지 몰라도 아래 run/debug config 화면에서 Enviroment 옵션이 보이지 않습니다. 유레카 실습 중이고 한개의 프로젝트에서 여러 서비스를 실행시킬 때 VM option을 사용해서 포트를 변경 하려 하는데 해당 옵션이 보이지 않아 문의 드립니다.

Modify options 에서 VM options 라는 항목이 따로 있네요...   혹시 run/debug configuration 창의 형태(?)를 강의 하시는 화면과 동일하게 변경하는 옵션이 따로 있을까요..?

안녕하세요.   입문강의를 다 듣고 이제 다음 강의로 넘어가 보려고 합니다. 하지만 입문강의를 들었을때 좀 벅차다라는 생각이 들었습니다.   흐름은 알겠으나, 이해가 안되는부분을 생각해보면 .(점)이나 ()(괄호) 부분의 사용처 입니다. 막상 제가 혼자 개발을 한다고 생각해보면 ex) member1 = new MMR(); member2 = new MS(member1); Member finMember = memberService.finOne(SaveId).get(); Member member = em.find(Member.class, id); @GeneratedValue(strataegy = GenerationType.IDENTITY)   위 예제처럼 ()안에 들어갈 때와 의미 어떨때 들어가는지, .get()이 추가 의미 및 언제 사용하고 어느때 사용 하는지, Member.class 처럼 .class는 언제 어느때 들어가고 왜들어가는지.. @GeneratedValue에 GenerationType.IDENTITY 선택은 왜 했는지.. Ctrl + Q누르면 설명이 나오긴하는데 감이 안잡힙니다.   어느 핀트를 잡고 그 원리대로만 가면 되는건지... 강사님이 말씀하신것처럼 망망대해처럼 제가 뭐가 부족해서 어떻게 공부를 해야 할 지 잘 모르겠습니다.
