* 프레임워크 : Spring Boot
* 프로젝트 : Gradle
* 데이터베이스 : firebase의 firestore
[결과]
[ Firestore ]
우선 파이어스토어에 다음과 같이 데이터를 넣는다.
(문서ID 를 FMgoGDQHyNQ7IfGycZ0h 이런 식으로 설정 할 필요는 없습니다!
제가 잘 모르고 자동완성ID를 한거에요ㅠ)

[ 실행 방법 ]
application을 선택한 후 재생버튼 클릭
인터넷 창을 켜서 다음을 입력한다.
http://localhost:8080/getMemberDetail?id=문서아이디
※ 나의 경우 9070 port를 이용했다. ( http://localhost:9070/getMemberDetail?id=FMgoGDQHyNQ7IfGycZ0h
id로 FMgoGDQHyNQ7IfGycZ0h
문서id FMgoGDQHyNQ7IfGycZ0h
+) 참고
localhost 8080을 이용하고 있어서 9070으로 변경했다.
application.properties
server.port=9070
+) 참고2
serviceAccountKey.json 을 resource 폴더에 저장해서 관리했다.
하지만 이대로 깃허브에 올리면 난리가 나므로 .gitignore에 추가했다.
