2024.04.19 - [A.I/RAG] - ai? 맨땅에 헤딩 -1(langChain) : ai와 공생하기!

기존에 python으로 langChain을 따라해보았는데 Spring Boot 진영에도 진작에 나왔었는데
해볼까 말까 하다가 이번 주말에는 해보기로 마음 먹었습니다. ㅋㅋ 
또한 Spring Boot를 사용하는데 파이썬쪽 호출하기가 귀찮기도하고 Java에서 함께 코딩하면 더 좋을것 같습니다.
단, 파이썬과 비교했을 때 코딩은 쉬운지 관련 라이브러리는 쉬운지 등등 안해봐도 알것 같지만 일단 해보겠습니다ㅋㅋㅋ

implementation 'org.springframework.ai:spring-ai-openai-spring-boot-starter'

일단 위의 lib를 추가하면 오류가 빵빵 터지는군요;;
오류를 보니 Open AI 관련 셋팅을 해줘야하나봅니다. 
    ㄴ application.yml에 open ai api-key를 세팅해주면 오류가 나지 않습니다 ㅎㅎ

spring:
  application:
    name: taehaPark
  ai:
    openai:
      api-key: sk-proj-블라블라

재밌겠다 ㅋㅋ
