해결방법

servlet version이 3.0 이상이어야 javax.servlet.http.HttpServletRequest.getAsyncContext() 해당 메소드가 존재하는데 servlet 버전이 낮아 해당 메소드가 존재하지 않아서 나는 에러이다. 내 경우에는 pom.xml에서 servlet version을 3.1로 맞추었지만 cors-filter에서 transitively하게 v2.5를 가져와서 해당 에러가 났다. 따라서 전이적으로 낮은 servlet 버전을 가져온 cors-filter의 버전을 1.3.2에서 2.5로 올려줬더니 getAsyncContext()를 찾는다.

또는

exclusion을 통해 버전을 잘못가져온 해당 라이브러리를 제외해주니 해결된다.
