springboot整合支付宝沙箱支付案例

很高兴能为您提供这篇文章，下面是springboot整合支付宝沙箱支付的案例。

1. 首先，您需要注册一个支付宝账号，并申请沙箱环境的权限。

2. 在支付宝开放平台申请应用，并获取应用的AppID、应用私钥和支付宝公钥。

3. 在pom.xml文件中添加以下依赖：

<dependency>
    <groupId>com.alipay.sdk</groupId>
    <artifactId>alipay-sdk-java</artifactId>
    <version>3.3.0.ALL</version>
</dependency>

4. 创建一个AliPayConfig类，用于配置支付宝相关参数。

@Configuration
public class AliPayConfig {
    //支付宝网关
    private String gatewayUrl;
    //商户应用id
    private String appid;
    //RSA私钥
    private String privateKey;
    //字符编码格式
    private String charset;
    //支付宝公钥
    private String alipayPublicKey;
    //签名类型
    private String signType;
    
    @Value("${ali.pay.gatewayUrl}")
    private String aliPayGatewayUrl;
    @Value("${ali.pay.appid}")
    private String aliPayAppid;
    @Value("${ali.pay.privateKey}")
    private String aliPayPrivateKey;
    @Value("${ali.pay.charset}")
    private String aliPayCharset;
    @Value("${ali.pay.alipayPublicKey}")
    private String aliPayAlipayPublicKey;
    @Value("${ali.pay.signType}")
    private String aliPaySignType;
    
    @PostConstruct
    public void init() {
        this.gatewayUrl = aliPayGatewayUrl;
        this.appid = aliPayAppid;
        this.privateKey = aliPayPrivateKey;
        this.charset = aliPayCharset;
        this.alipayPublicKey = aliPayAlipayPublicKey;
        this.signType = aliPaySignType;
    }
    
    @Bean
    public AlipayClient alipayClient() {
        return new DefaultAlipayClient(gatewayUrl, appid, privateKey, "json", charset, alipayPublicKey, signType);
    }
}

5. 创建一个AliPayService类，用于处理支付宝相关业务逻辑。

@Service
public class AliPayService {
    @Autowired
    private AlipayClient alipayClient;
    @Value("${ali.pay.notifyUrl}")
    private String aliPayNotifyUrl;
    
    public String aliPay(String orderId, String totalAmount, String subject) {
        String result = "";
        AlipayTradePagePayRequest alipayRequest = new AlipayTradePagePayRequest();
        alipayRequest.setReturnUrl("http://localhost:8080/returnUrl");
        alipayRequest.setNotifyUrl(aliPayNotifyUrl);
        alipayRequest.setBizContent("{\"out_trade_no\":\"" + orderId + "\","
                + "\"total_amount\":\"" + totalAmount + "\","
                + "\"subject\":\"" + subject + "\","
                + "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");
        try {
            result = alipayClient.pageExecute(alipayRequest).getBody();
        } catch (AlipayApiException e) {
            e.printStackTrace();
        }
        return result;
    }
    
    public void aliPayNotify(Map<String, String> params) {
        boolean verifyResult = false;
        try {
            verifyResult = AlipaySignature.rsaCheckV1(params, alipayClient.getAlipayPublicKey(), "UTF-8", "RSA2");
        } catch (AlipayApiException e) {
            e.printStackTrace();
        }
        if (verifyResult) {
            String outTradeNo = params.get("out_trade_no");
            String tradeNo = params.get("trade_no");
            String tradeStatus = params.get("trade_status");
            if ("TRADE_SUCCESS".equals(tradeStatus)) {
                //支付成功
            }
        }
    }
}

6. 在controller中调用AliPayService类进行支付宝支付。

@Controller
public class AliPayController {
    @Autowired
    private AliPayService aliPayService;
    
    @RequestMapping("/aliPay")
    @ResponseBody
    public String aliPay(HttpServletRequest request, HttpServletResponse response) throws IOException {
        String orderId = "201908140020000001";
        String totalAmount = "0.01";
        String subject = "测试支付";
        String result = aliPayService.aliPay(orderId, totalAmount, subject);
        return result;
    }
    
    @RequestMapping("/returnUrl")
    public String returnUrl(HttpServletRequest request, HttpServletResponse response) throws IOException {
        Map<String, String> params = new HashMap<>();
        Map<String, String[]> requestParams = request.getParameterMap();
        for (Iterator<String> iter = requestParams.keySet().iterator(); iter.hasNext();) {
            String name = iter.next();
            String[] values = requestParams.get(name);
            String valueStr = "";
            for (int i = 0; i < values.length; i++) {
                valueStr = (i == values.length - 1) ? valueStr + values[i] : valueStr + values[i] + ",";
            }
            params.put(name, valueStr);
        }
        aliPayService.aliPayNotify(params);
        return "success";
    }
}
