에러 요약

1. Failed to instantiate ...Error creating bean with name 'mvcHandlerMappingIntrospector' defined in class path resource
   - bean을 생성하는 데에 실패함
2. Invalid mapping on handler class [com.example.petstargram.controller.ArticleController]: public org.springframework.http.ResponseEntity com.example.petstargram.controller.ArticleController.updateComment(long,com.example.petstargram.dto.UpdateCommentDto)
   • 유효하지 않은 mapping이 ArticleController에서 발생하였다.

ArticleController을 살펴보았다.
기존 코드
@PutMapping("/api/articles/${commentId}")

-> 경로가 잘못 설정되었다.
경로를 제대로 보자! 특수문자가 들어가서 그랬다..😥
/api/comments/${commentId} ->/api/comments/{commentId}변경하니 컴파일이 제대로 되었다!😊
