PayPay API Springbootで配置 爆速

1.Mavenで配置

<dependency>
    <groupId>jp.ne.paypay</groupId>
    <artifactId>paypayopa</artifactId>
    <version>1.0.8</version>
</dependency>

2.ユーザー認証

private static final String YOUR_API_KEY = "";
private static final String YOUR_API_SECRET = "";
private static final String YOUR_MERCHANT_KEY = "";
private static final ApiClient apiClient;
static {
    try {
        apiClient = new Configuration().getDefaultApiClient();
        apiClient.setProductionMode(false);
        apiClient.setApiKey(YOUR_API_KEY);
        apiClient.setApiSecretKey(YOUR_API_SECRET);
        apiClient.setAssumeMerchant(YOUR_MERCHANT_KEY);
    } catch (ApiException e) {
        throw new RuntimeException(e);
    }
}

     * @param payAmount 
     * @param orderDescription 
     * @return 
     */
    public static QRCodeResponse getQrCode(String merchantPaymentId, Integer payAmount, String orderDescription) throws ApiException {
        QRCode qrCode = new QRCode();
        qrCode.setAmount(new MoneyAmount().amount(payAmount).currency(MoneyAmount.CurrencyEnum.JPY));
        qrCode.setMerchantPaymentId(merchantPaymentId);
        qrCode.setCodeType("ORDER_QR");
        qrCode.setOrderDescription(orderDescription);
        qrCode.isAuthorization(false);
        PaymentApi apiInstance = new PaymentApi(apiClient);

            throw new RuntimeException((response.getResultInfo().getMessage()));
        }
        return responseData;
    }

3.1.1 Test result

private static final String PRODUCT_PAY_PAY = "PayOr";

@Test
public void createPaymentTest() {
    String orderNo = IdUtil.getSnowflake(0, 0).nextIdStr();
    System.out.println("注文番号をランダムに生成する" + orderNo);
    QRCodeResponse QRCodeResponse = new QRCodeResponse();
    try {
        String merchantPaymentId = PRODUCT_PAY_PAY + orderNo;
        String orderDescription = "テスト";
        Integer paAmount = 1;
        QRCodeResponse = getQrCode(merchantPaymentId, paAmount, orderDescription);
    } catch (ApiException e) {
        System.out.println("Error code : " + e.getMessage());
        throw new RuntimeException(e);
    }
    System.out.println(QRCodeResponse);
    System.out.println(QRCodeResponse.getUrl());
