如何将 for 循环放入 JavaMailSender 的 html 字符串内容中？

问题描述

我通过邮件向用户发送订单确认这是我的订单结账控制器：

@PostMapping("/purchase")
    public PurchaseResponse placeOrder(@RequestBody Purchase purchase) {

        PurchaseResponse purchaseResponse = checkoutService.placeOrder(purchase);

        sendOrderConfirmationMail(purchase,purchaseResponse);


        return purchaseResponse;
    }


    private void sendOrderConfirmationMail(Purchase purchase,PurchaseResponse purchaseResponse) {

        //List<OrderItem> orderItemList = (List<OrderItem>) purchase.getorderItems();

        String content="<html>\n" +
                "<body>\n" +
                "    <h3>WWW.HobbyShop.com</h3>\n" +
                "    <h3>Thank You for your purchase,</h3>" + purchase.getCustomer().getFirstName() + " " + purchase.getCustomer().getLastName() + "\n" +
                "    <h3>Order summary</h3>\n" +



                "    <h3><b>Order Details</b></h3>\n" +
                "    <h5>Your order will ship to:</h5>\n" +
                        purchase.getCustomer().getFirstName() + " " + purchase.getCustomer().getLastName() + ",\n" +
                        purchase.getShippingAddress().getStreet() + ",\n" +
                        purchase.getShippingAddress().getCity() + "," + purchase.getShippingAddress().getState() + " " + purchase.getShippingAddress().getZipCode() + "\n" +
                        purchase.getShippingAddress().getCountry() + "\n" +
                "    <h5>Your order Tracking Number:</h5>\n" +
                        purchaseResponse.getorderTrackingNumber() + "\n" +
                "</body>\n" +
                "</html>";


        mailService.sendHtmlMail(purchase.getCustomer().getEmail(),"ORDER CONFIRMED",content);
    }

我正在尝试像这样循环遍历字符串内容中的订单项：查看评论

private void sendOrderConfirmationMail(Purchase purchase,PurchaseResponse purchaseResponse) {

        List<OrderItem> orderItemList = (List<OrderItem>) purchase.getorderItems();

        String content="<html>\n" +
                "<body>\n" +
                "    <h3>WWW.HobbyShop.com</h3>\n" +
                "    <h3>Thank You for your purchase,</h3>" + purchase.getCustomer().getFirstName() + " " + purchase.getCustomer().getLastName() + "\n" +
                "    <h3>Order summary</h3>\n" +

                
                // displaying order item by looping through the orderItem list
                
                        for (OrderItem orderItem : orderItemList) {
                             orderItem.getName() + "\n" +
                                      "<img src='" + orderItem.getimageUrl() + "'>\n" +
                                      orderItem.getQuantity() + "\n" +
                                      orderItem.getUnitPrice() + "\n" +
     
                          } +
                
                


                "    <h3><b>Order Details</b></h3>\n" +
                "    <h5>Your order will ship to:</h5>\n" +
                        purchase.getCustomer().getFirstName() + " " + purchase.getCustomer().getLastName() + ",content);
    }

但它给了我这样的错误：


';' expected
Expression expected

如果我删除 for 循环，错误就会消失并且它可以工作，但我想遍历 orderItemList 以显示用户订单项。

那么，如何在 html 字符串内容中添加 for 循环？
