SpringBoot 支付寶付款接口類、支付異步回調(diào)函數(shù)模板

1.付款接口類

1.1.引入Maven依賴

<dependency>
    <groupId>com.alipay.sdk</groupId>
    <artifactId>alipay-sdk-java</artifactId>
    <version>4.38.221.ALL</version>
</dependency>

1.2.將下面代碼保存為AlipayTemplate.java

@Configuration
@ConfigurationProperties("alipay")
@Data
public class AlipayTemplate {
    private String notifyUrl="";
    private String returnUrl="";

    private String serverUrl;//網(wǎng)關(guān)地址
    private String appId;//應(yīng)用ID
    private String privateKey;//私鑰
    private String format="json";
    private String charset="UTF-8";
    private String alipayPublicKey;//公鑰
    private String signType="RSA2";

    public String pay(String outTradeNo, BigDecimal totalAmount,String subject) throws AlipayApiException {
        AlipayClient alipayClient = new DefaultAlipayClient(
                serverUrl,//網(wǎng)關(guān)地址
                appId,//應(yīng)用ID
                privateKey,//私鑰
                format,
                charset,
                alipayPublicKey,//公鑰
                signType//加密算法
        );
        AlipayTradePagePayRequest request = new AlipayTradePagePayRequest();
        //異步接收地址，僅支持http/https，公網(wǎng)可訪問
        request.setNotifyUrl(notifyUrl);
        //同步跳轉(zhuǎn)地址，僅支持http/https
        request.setReturnUrl(returnUrl);
        /******必傳參數(shù)******/
        JSONObject bizContent = new JSONObject();
        //商戶訂單號(hào)，商家自定義，保持唯一性
        bizContent.put("out_trade_no", outTradeNo);
        //支付金額，最小值0.01元，保留兩位小數(shù)向上取整
        bizContent.put("total_amount", totalAmount.setScale(2, RoundingMode.UP));
        //訂單標(biāo)題，不可使用特殊符號(hào)
        bizContent.put("subject", subject);
        //電腦網(wǎng)站支付場(chǎng)景固定傳值FAST_INSTANT_TRADE_PAY
        bizContent.put("product_code", "FAST_INSTANT_TRADE_PAY");

        /******可選參數(shù)******/
        /**
         * time_expire可選string(32)
         * 【描述】訂單絕對(duì)超時(shí)時(shí)間。
         * 格式為yyyy-MM-dd HH:mm:ss。超時(shí)時(shí)間范圍：1m~15d。
         * 注：time_expire和timeout_express兩者只需傳入一個(gè)或者都不傳，兩者均傳入時(shí)，優(yōu)先使用time_expire。
         * 【示例值】2016-12-31 10:05:01
         */
        //bizContent.put("time_expire", LocalDateTime.now(ZoneId.of("Asia/Shanghai")).plusMinutes(1).format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")));


        //// 商品明細(xì)信息，按需傳入
        //JSONArray goodsDetail = new JSONArray();
        //JSONObject goods1 = new JSONObject();
        //goods1.put("goods_id", "goodsNo1");
        //goods1.put("goods_name", "子商品1");
        //goods1.put("quantity", 1);
        //goods1.put("price", 0.01);
        //goodsDetail.add(goods1);
        //bizContent.put("goods_detail", goodsDetail);

        //// 擴(kuò)展信息，按需傳入
        //JSONObject extendParams = new JSONObject();
        //extendParams.put("sys_service_provider_id", "2088511833207846");
        //bizContent.put("extend_params", extendParams);

        request.setBizContent(bizContent.toString());
        AlipayTradePagePayResponse response = alipayClient.pageExecute(request,"POST");
        // 如果需要返回GET請(qǐng)求，請(qǐng)使用
        // AlipayTradePagePayResponse response = alipayClient.pageExecute(request,"GET");
        String pageRedirectionData = response.getBody();
        // System.out.println(pageRedirectionData);
        return pageRedirectionData;
        /*if(response.isSuccess()){
            System.out.println("調(diào)用成功");
        } else {
            System.out.println("調(diào)用失敗");
        }*/
    }
}

1.3.支付調(diào)用范例

@RequiredArgsConstructor
@Controller
public class PayWebController {
    private final AlipayTemplate alipayTemplate;//依賴注入
    @ResponseBody
    @GetMapping(value = "/pay",produces = MediaType.TEXT_HTML_VALUE)
    public String payOrder(@RequestParam("orderSn") String orderSn) throws AlipayApiException {//傳入orderSn訂單號(hào)
        BigDecimal totalAmount = new BigDecimal(100);//支付金額
        String subject = "支付測(cè)試";//支付標(biāo)題
        return alipayTemplate.pay(orderSn,totalAmount,subject);
    }
}

2. 支付異步回調(diào)函數(shù)模板

@RequiredArgsConstructor
@Controller
public class payedListener {
    private final AlipayTemplate alipayTemplate;
    @ResponseBody
    @PostMapping("/payed/notify")
    public String handleAlipayed(@RequestParam Map<String,String> paramsMap) throws AlipayApiException {
        try {
            boolean signVerified = AlipaySignature.rsaCheckV1(paramsMap, alipayTemplate.getAlipayPublicKey(), alipayTemplate.getCharset(), alipayTemplate.getSignType()); //調(diào)用SDK驗(yàn)證簽名
            if(signVerified){
                //驗(yàn)簽成功，執(zhí)行正常業(yè)務(wù)代碼
                return "success";
            }else{
                //驗(yàn)簽失敗
            }
        }catch (Exception ignored){
        }
        return "failure";
    }
}
