#489942 Tech Q&A jsp jsp질문 jsp고수 db java enctype="multipart/f multipart/form-data

JSP multipart/form-data 파라미터 값처리.. 질문 드립니다 ㅠㅠ

아무리 해도 안되서 이렇게 질문 올립니다. ㅠㅠ

JSP 고수님 한번만 봐주세요 ㅠㅠㅠㅠ

 enctype="multipart/form-data" 형식으로 파일을 전송할때 

bbs.setBbsTitle(multi.getParameter("bbsTitle")); 이런 씩으로 받아와서 치리 하도록 했는데

글쓰기 하면 자꾸 -1 에러 뜨네요 ㅠ

------------------------------

test.jsp 파일 만들어서 여기로 값을 넘겼는데 잘넘어 와요 ㅠㅠ 이거 그러면 BbsDAO.JAVA 파일에 write 부분에 문제 가있는건가요? ㅠㅜ

String aa="";

aa=multi.getParameter("bbsTitle");

    어느 부분을 건드려야 할지 모르겠어요 ㅠㅠ

    해당 테이블 검색 해보니깐 PK 중복 된 부분은 없어여 ㅠ


    | bbs   | CREATE TABLE `bbs` (

      `bbsID` int(11) NOT NULL,

      `bbsTitle` varchar(50) DEFAULT NULL,

      `userID` varchar(20) DEFAULT NULL,

      `bbsDate` datetime DEFAULT NULL,

      `bbsContent` varchar(2048) DEFAULT NULL,

      `fieldName` varchar(50) DEFAULT NULL,

      `fieldNamea` varchar(75) DEFAULT NULL,

      `bbsFigure` varchar(30) DEFAULT '0',

      PRIMARY KEY (`bbsID`)

    pstmt.setInt(1, getNext());

    이게 아마 bbsID 조회해온후 할당하시는거같은데 
    PK 값이 2인데 INSERT 를 2로 해서 중복이라는거같아요.

    getNext()  <--  쿼리확인해보세요 어떤식으로가져오시는지

    bbsID 에 동일한 값이 두번 들어가는 것 같은데요...

    혹시 pstmt 를 로그로 찍으면 어떻게 나오나요??

    혹시나 싶어서 DB데이터 내용다 삭제 하니깐 해결은 되는거에요 ㅠㅠ 그래서 글쓰기 하고 삭제하고 다시 글쓰기 하면 안되더라고요 ㅠ원인을 알아보니 bbsAvailable = 1  이 아이가 문제였으여 ㅠㅠ

    다들 감사합니다. ㅠㅠ

    getNext() 쿼리보면 이렇게 

    public int getNext() {

    String SQL = "SELECT bbsID FROM BBS WHERE bbsAvailable = 1 ORDER BY bbsID DESC";

    try {

    PreparedStatement pstmt = conn.prepareStatement(SQL);

    rs = pstmt.executeQuery();

    if(rs.next()) {

    return rs.getInt(1) + 1;

    }

    return 1; //첫번째 게시물인 경우

    } catch (Exception e) {

    e.printStackTrace();

    }return -1;// 데이터 베이스 오류

    }
