[오류] Ajax에서 404
url을 똑같이 mapping 했는데 404 에러가 났다.
오류를 읽어보니 web.xml에서 servlet 설정을 다시 해야된다는 것 같다.
비동기가 여러군데에서 실행되어 충돌되는 것 같은데,
아직 정확한 원인이 뭔지 모르겠다.
같은 팀원이 web socket으로 화상채팅, 채팅을 구현하고 있는데
그것때문에 자꾸 충돌이 나는 것 같다.
java.lang.IllegalArgumentException: Async support must be enabled on a servlet and for all filters involved in async request processing. This is done in Java code using the Servlet API or by adding "<async-supported>true</async-supported>" to servlet and filter declarations in web.xml. Also you must use a Servlet 3.0+ container

at java.lang.Thread.run(Thread.java:745)=> 이 오류는 webSocket 문제가 맞는데 ,
404 오류는 VO가 잘못되어서 오류가 났다.
VO에서 편리하게 format처리하도록 부장님이 알려주셨는데, 그 처리를 하는 중에
아래 VO에서 public String getProdInfoNmDisplay() 메서드에서 prodInfoNm이 Null값일때에도 실행되었기 때문에 Nullpointer 오류가 나고 404에러가 났던 것이다.
if로 null값일 경우를 따로 빼주니까 오류가 사라졌다.
