Excel파일을 DB에 올리는(Insert)작업중이다.

HSSF 경우 xls의 2003버젼.
XSSF의경우 xlsx의 2007버젼 중심.

구조가 크게 달라짐에 따라 이도 완전 다르게 동작하는듯하다.

결론만 말하자면 새로운 엑셀파일은 같은 내용이라도 전체의 파일 크기는 줄었지만
읽으려면 전체를 메모리에 로드 해 놓고 있어야한다고 한다.
그래서 java heap space 에러가 금방 난다고...(Tomcat기준)

결론은 xls(2003버젼용)으로 저장하여 올리면 용량은 더 늘어나지만 잘 올라간다.
물론 limit은 있겠지? infinity는 아닐것같은데;;;
