仅在 spring 启动休息 api 中集成 PayPal

Question

我正在尝试使用此 link 将 PayPal 集成到 spring 启动应用程序中， https://developer.paypal.com/docs/api/quickstart/payments/#define-payment 但出现如下异常：

2021-03-17 18:37:43.283  INFO 2932 --- [nio-9001-exec-1] d.b.o.controller.PaypalEndpoint          : EXception occred

    at com.paypal.api.payments.Payment.create(Payment.java:149)


public Payment createPayment(
            Double total,
            String currency,
            String method,
            String intent,
            String description,
            String cancelUrl,
            String successUrl) throws PayPalRESTException{

        Details details = new Details();
        details.setShipping("1");
        details.setSubtotal("1");
        details.setTax("1");

        Amount amount = new Amount();
        amount.setCurrency(currency);

        total = new BigDecimal(total).setScale(2, RoundingMode.HALF_UP).doubleValue();
        amount.setTotal(String.format("%.2f", total));
        amount.setDetails(details);

        Transaction transaction = new Transaction();
        transaction.setDescription(description);
        transaction.setAmount(amount);

        List<Transaction> transactions = new ArrayList<>();
        transactions.add(transaction);

        Payer payer = new Payer();
        payer.setPaymentMethod(method);

        Payment payment = new Payment();
        payment.setIntent(intent);
        payment.setPayer(payer);
        payment.setTransactions(transactions);
        RedirectUrls redirectUrls = new RedirectUrls();
        redirectUrls.setCancelUrl(cancelUrl);
        redirectUrls.setReturnUrl(successUrl);
        payment.setRedirectUrls(redirectUrls);

        return payment.create(apiContext);
    }

我认为异常发生在

return payment.create(apiContext);

apiContext 有价值。谁能告诉我问题出在哪里？

您正在尝试使用已弃用的 API，不应将其用于任何新集成。

改为与 REST 集成 v2/checkout/orders。请参阅 'Create Order' 和 'Capture Order' https://developer.paypal.com/docs/business/checkout/server-side-api-calls/#server-side-api-calls
