스프링 부트 웹소켓 빈 등록 오류

백엔드 서버개발을 통합하고, 머지하는 과정에서 빈등록이 안된다는 오류가 발생했다.

 

아래는 에러 목록이다.

빈 등록이 안된다는 알 수도 없는 말에, 이것저것 확인해봤는데

어노테이션도 제대로 주입했고, 의존성도 제대로 주입했는데

계속 에러가 나서 2시간동안 잡고 하나하나 디버깅한 끝에 원인을 알 수 있었다.

 

//webjars
implementation 'org.webjars:webjars-locator-core'
implementation 'org.webjars:sockjs-client:1.0.2'
implementation 'org.webjars:stomp-websocket:2.3.3'
implementation 'org.webjars:bootstrap:3.3.7'
implementation 'org.webjars:jquery:3.1.1-1'

 

내가 웹소켓을 구현할 때 사용한 라이브러리다.

 

그런데 다른 팀원도 웹소켓을 구현했는데 다른 라이브러리를 이용했다.

 

implementation 'org.springframework:spring-messaging:5.3.0'
implementation 'org.springframework:spring-websocket:5.3.0'

 

두 웹소켓이 충돌이 일어나서 빈등록이 제대로 안되는 오류였다.

 

우리는 라이브러리를 하나로 통일해서 오류를 수정했다.
