  It's because we didn't finally release the resources It corresponds to a violation of the web vulnerability. ex) Connection conn = null; PreparedStatement pstmt = null; ResultSet rs = null; try { // conn , pstmt , rs code }catch(NullPointerException e){ finally{ if(rs!=null){rs.close();} if(pstmt!=null){pstmt.close();} if(conn!=null){conn.close();} } 😀 Thank you !! 감사합니다 !!
