집에서 포트폴리오 작업을 할 때 , 2~3일동안 세팅 하는데 너무나도 어려웠다.
2~3일동안 세팅하면서 깨달았던 점을 작성하려고 한다.
❌ 오류 내용 :
1. 서블릿 [appServlet]을(를) 위한 Servlet.init() 호출이 예외를 발생시켰습니다. - UnsatisfiedDependencyException / BeanCreationException <br/>
2. java.lang.IllegalStateException: Cannot load configuration class: com.springCommunity.service.WebSocketConfig <br/>
1.해당 오류는 appServlet에서 Bean과 관련된 오류이기 때문에 , servlet-context.xml을 들어가 오류에 해당하는 내용을 찾아봤다.
그러나 결과적으로 잘못된 내용은 없었고 , sts의 오류였다. project 클린 후 재부팅 하니 오류는 사라졌다.

<br/>
오류 내용
✔️ 해결방법 <br/>
기존에 작성한 pom.xml과 나의 컴퓨터에 설정된 내용이 맞지 않아서 오류가 발생하고 있었다. <br/>
근본 원인을 위에서부터 하나씩 보았다.<br/>
웹소켓과 관련된 jar를 추가해야한다는 내용을 보고 , 아래의 내용을 pom.xml에 추가하였다 .<br/>
그 후에 Run on Server를 실행해도 [그림1,2,3]의 오류가 발생하였고, 웹 소켓이 아닌 시큐리티와 호환이 맞지 않을 수도 있다는 생각이 들게 되었고, pom.xml의 RELEASE부분을 업그레이드 시켰더니 잘 작동하게 되었다.<br/>

📗 느낀 점 :
java.lang.IllegalStateException: Cannot load configuration class: com.springCommunity.service.WebSocketConfig 오류의 근본원인의 WebSocketConfig의 부분만 보고 웹 소켓 문제인게 아닌가 하고 찾아본게 너무나도 시간을 오래 끌게된 원인으로 느꼈다. <br/>
또한 security를 생각하지 못했던게 아쉬웠다.. <br/>
