Java上的PreparedStatement问题

Question

我的pstmt.executeUpdate()出错。.

由于助手的帮助，我找不到错误的原因

public void createCoupon(Coupon coupon) throws Exception {
    Connection connection = DriverManager.getConnection(DB.Database.getUrl(), DB.Database.getUser(),
            DB.Database.getPass());

    String sql = "INSERT INTO COUPON (ID, TITLE, START_DATE, END_DATE, AMOUNT, TYPE, MESSAGE, PRICE, IMAGE) VALUES (?,?,?,?,?,?,?,?,?)";
    try (PreparedStatement pstmt = connection.prepareStatement(sql)) {

        pstmt.setInt(1, coupon.getId());
        pstmt.setString(2, coupon.getTitle());

        pstmt.setDate(3,(java.sql.Date) coupon.getStart_date());
        pstmt.setDate(4,(java.sql.Date) coupon.getEnd_date());
        pstmt.setInt(5,coupon.getAmount());
        pstmt.setString(6, coupon.getType().name());
        pstmt.setString(7, coupon.getMessage());
        pstmt.setDouble(8, coupon.getPrice());
        pstmt.setString(9, coupon.getImage());

        pstmt.executeUpdate();
        System.out.println("Insert " + coupon + " succeed ");
    } catch (SQLException e) {
        e.printStackTrace();
        throw new Exception("Coupon insert failed");

    } finally {
        connection.close();
    }

}
