当面付(Face to Face payment)是支付宝提供的一种支付方式,可以在线下场景进行交易支付。以下是一个简单的Spring Boot集成支付宝当面付的示例代码:
首先,添加依赖到 `pom.xml` 文件中:
```xml
<dependency>
<groupId>com.alipay.sdk</groupId>
<artifactId>alipay-sdk-java</artifactId>
<version>4.15.3.ALL</version>
</dependency>
```
然后,创建一个支付服务类 `AlipayService.java`,用于发起支付请求和处理支付结果:
```java
import com.alipay.api.AlipayApiException;
import com.alipay.api.DefaultAlipayClient;
import com.alipay.api.request.AlipayTradePrecreateRequest;
import com.alipay.api.response.AlipayTradePrecreateResponse;
public class AlipayService {
private static final String ALIPAY_APP_ID = "your_app_id";
private static final String ALIPAY_PRIVATE_KEY = "your_private_key";
private static final String ALIPAY_PUBLIC_KEY = "your_public_key";
private static final String ALIPAY_GATEWAY_URL = "https://openapi.alipay.com/gateway.do";
public String createQRCode(String outTradeNo, String subject, String totalAmount) throws AlipayApiException {
DefaultAlipayClient alipayClient = new DefaultAlipayClient(ALIPAY_GATEWAY_URL, ALIPAY_APP_ID, ALIPAY_PRIVATE_KEY, "json", "UTF-8", ALIPAY_PUBLIC_KEY);
AlipayTradePrecreateRequest request = new AlipayTradePrecreateRequest();
request.setNotifyUrl("your_notify_url"); // 异步通知回调地址
request.setBizContent("{" +
"\"out_trade_no\":\"" + outTradeNo + "\"," +
"\"total_amount\":\"" + totalAmount + "\"," +
"\"subject\":\"" + subject + "\"" +
"}");
AlipayTradePrecreateResponse response = alipayClient.execute(request);
if (response.isSuccess()) {
return response.getQrCode();
} else {
throw new AlipayApiException(response.getMsg());
}
}
}
```
最后,在你的控制器中使用 `AlipayService` 类来生成支付二维码:
```java
import com.alipay.api.AlipayApiException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/payment")
public class PaymentController {
@Autowired
private AlipayService alipayService;
@GetMapping("/createQRCode")
public String createQRCode() {
try {
String outTradeNo = "your_out_trade_no";
String subject = "your_subject";
String totalAmount = "your_total_amount";
String qrCode = alipayService.createQRCode(outTradeNo, subject, totalAmount);
return qrCode;
} catch (AlipayApiException e) {
e.printStackTrace();
return "Failed to create QR code.";
}
}
}
```
以上代码中的 `your_app_id`、`your_private_key`、`your_public_key`、`your_notify_url`、`your_out_trade_no`、`your_subject`、`your_total_amount` 需要替换为你自己的支付宝配置和业务参数。
请注意,这只是一个简单的示例,实际使用时需要根据自己的业务需求进行适当的修改和完善。同时,为了保证支付的安全性和可靠性,建议在真实环境中使用HTTPS协议和其他安全机制。
