Google App engine 스프링 + JPA 연동 (앱엔진 스프링 JPA)

이곳은 피피티가 복붙이 안되기 때문에 복붙을 위하여 막 적는 곳이다. 


삽질을 하면서 실시간으로 피피티를 만들다 보니 피피티가 좀 깔끔하지가 않다. ㅡㅡ;;

이해해주시길 바란다. 




그 다음으로 어디보자..소스들을 적어보자면..


자주쓰는 메이븐 명령어 : 

실행파일들 깨끗하게 mvn clean

이클립스로 만들어주는 것 mvn eclipse:eclipse 

로컬에서 실행시 쓰는 명령어 : mvn appengine:devserver 

서버로 올릴때 명령어 mvn appengine:update



앱엔진 사이트 

아...피피티에서 복붙을 그대로 하니 그대로 나온다 ㅡㅡ;; 


https://cloud.google.com/appengine/
그 다음에 이클립스 플러그인들 주소 : 

https://cloud.google.com/appengine/docs/java/tools/eclipse




자기 앱 확인 사이트!

https://appengine.google.com/



메이븐 빌드 적용 부분..

메이븐명령어 (참고로 그냥 처음에 mvn archetype:generate 를 해주고 일일이 정해줘도 된다)  

mvn archetype:generate -Dappengine-version=1.9.17 -Dapplication-id=앱아이디 -Dfilter=com.google.appengine.archetypes:


이거 해준다음에 아마 mvn eclipse:eclipse 해줬었지 아마...
