springboot google ocr api 호출하기!

1. 키 발급

서비스 계정 클릭-> 대충 만들고->밑에 서비스 계정 확인-> 클릭-> 키 클릭-> 키 추가-> 새키 만들기

키를 받아서 원하는 곳에 위치시킨다

2. 환경변수 등록

경로를 잡아준다

3. 디펜던시 추가

implementation group: 'com.google.cloud', name: 'spring-cloud-gcp-starter', version: '2.0.7'

implementation 'com.google.cloud:google-cloud-vision:2.0.17'

(아마 implementation 'com.google.cloud:google-cloud-vision:2.0.17'것만 있어도 된다 )

공식문서에서 복붙 했다

근데 링크를 잃어버렸다...

내일 찾아봐야겠다 ㅠㅠ
