        PreparedStatement preparedStatement = null;


        //String date = new SimpleDateFormat("yyyy-MM-dd").format(new Date());


        String sql = "INSERT INTO invoice_description"
                + "(descId, invoiceId, description, quantity, price, total) VALUES"
                + "(NULL,?,?,?,?,?)";

        try {

            dbConnection = getDBConnection();

            preparedStatement = dbConnection.prepareStatement(sql);

            preparedStatement.setLong(1, invoiceId);
            preparedStatement.setString(2, description);
            preparedStatement.setInt(3, quantity);
            preparedStatement.setInt(4, price);
            preparedStatement.setInt(5, lineTotal);

            preparedStatement.executeUpdate();

            System.out.println("You have successfully added descriptions to invoice");


        } catch (SQLException e){

            System.out.println(e.getMessage());

        }
    }

控制器：

@RequestMapping(value = "/invoice", method = RequestMethod.POST)
    public String submitInvoice(HttpServletRequest request, 
            @RequestParam("clients") int clientId,
            @RequestParam("invoice_date") String invoice_date, 
            @RequestParam("invoice_due_date") String invoice_due_date, 
            @RequestParam("status") String status, 
            @RequestParam("payment_method") String payment_method, 
            @RequestParam("currency") String currency, 
            @RequestParam("description") String description, 
            @RequestParam("quantity") int quantity, 
            @RequestParam("price") int price, 
            @RequestParam("lineTotal") int lineTotal) {

        if(!hasRole(request, "ROLE_USER")){
            return "403";
        }


        long invoiceId = DBManager.createInvoice(clientId, invoice_date, invoice_due_date, status, payment_method, currency);
        DBManager.invoiceDescription(invoiceId, description, quantity, price, lineTotal);


        return "redirect:/createInvoice";
    }

您好。我试图将具有相同输入名称的数据插入invoice_description表。它插入时没有任何错误，但不是多行。我的目标是拥有多个具有唯一ID的行，但特定发票号的invoiceId（FK）相同。

请帮忙

插入具有两个具有相同名称的输入字段的多行
