message가 공백으로 나올 때

start.spring.io에서 강의 버전보다 높게 설정되어서 그런지 몰라도! 포스트맨으로 같은 name을 두개 post 보내면!!

아래와 같이 message는 빈 문자열이고 , stacktrace는 보이지 않습니다. 저는 여기서 1편 복습을 제대로 안했구나 어느 코드에서 error가 있는건지 멘붕이 터지게 됩니다 ㅠ ㅜ

{
"timestamp": "2020-12-22T13:15:21.478+00:00",
"status": 500,
"error": "Internal Server Error",
"message": "",
"path": "/api/v1/members"
}

그러다가 인터넷에 메시지 전달 안되는걸 대략 쳐보니...

main에 있는 application.yml에 server error를 설정해주면 해결 된다는것을 발견했습니다. 저처럼 처음 스프링을 접하는 사람은 강의와 조금만 달라져도 당황.. 그 자체!!

아래와 같이 입력 해주시면 강의 똑같은 postman 결과값을 받아 볼 수 있습니다.

server:
  error:
    include-stacktrace: always
    include-message: always

message, trace도 정상 출력 !!
