인프런 커뮤니티 질문&답변

선생님 빠른 답장 너무 감사합니다.

uploadForm.jsp에서

<form class="form-horizontal" action="<c:url value='/upload.do'/>" enctype="multipart/form-data" method="post">이 부분에서 mulitpart/form-data로 오타가 있었습니다. 이런거로 질문해서 죄송합니다.

좋은 하루 보내십시오!

코드에 노란줄이 나는부분은 에러가 아니면 크게 상관은 없습니다. 노란색 부분을 없애기 위해서는 자세한 메세지를 봐야겠지만 일단@SuppressWarnings("unchecked") 이부분은 하지마시고 코드에 Enumeration<String> 부분에서 <String>이 들어가 있는지 확인해보시고 업로드 API가 정확하게 import되었는지도 한번 확인해보시면 좋겠습니다.^^

혹시몰라 콘솔에 에러도 첨부합니다. 감사합니다.
