    public static void main(String[] args) {
        try {
            Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/sakila", "root", "ko875491");
            Statement stmt = con.createStatement();
            ResultSet rs = stmt.executeQuery("select film_id, title from sakila.film;");
            while (rs.next()) {
                System.out.println(rs.getInt(1) + "  " + rs.getString(2));
            }
            con.close();
        } catch (SQLException e) {
            System.out.println(e);
        }
    }

}

Netbeans 8.2 / MySQL Workbench 8.0.13版/在库中添加了MySQL JDBC驱动程序,并抛出此错误:

  

java.sql.SQLException:java.lang.ClassCastException:   无法将java.math.BigInteger强制转换为java.lang.Long

任何人都知道发生了什么事或有什么想法?
