好的,关于整合农行支付,我可以给你一些参考。首先,你需要在农行官网上注册账号,并且申请开通网银支付功能。然后,你需要获取到农行支付的接口文档和密钥信息,这些都是必要的前置条件。
接下来,你可以使用Spring Boot的HTTP客户端来发送POST请求,调用农行支付接口。具体实现可以参考以下步骤:
1. 首先,在Spring Boot项目中引入HTTP客户端依赖,比如Apache HttpClient或OkHttp等。
2. 创建一个支付服务类,定义发送支付请求的方法,例如:
```java
public class ABCPaymentService {
private CloseableHttpClient httpClient;
private String apiUrl;
private String merchantId;
private String terminalId;
private String publicKey;
private String privateKey;
public ABCPaymentService(String apiUrl, String merchantId, String terminalId, String publicKey, String privateKey) {
this.httpClient = HttpClients.createDefault();
this.apiUrl = apiUrl;
this.merchantId = merchantId;
this.terminalId = terminalId;
this.publicKey = publicKey;
this.privateKey = privateKey;
}
public String sendPaymentRequest(String orderId, BigDecimal amount, String returnUrl) {
// 构造请求参数
Map<String, String> params = new HashMap<>();
params.put("version", "v1.0.0");
params.put("merId", merchantId);
params.put("termId", terminalId);
params.put("orderId", orderId);
params.put("txnTime", LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyyMMddHHmmss")));
params.put("txnAmt", amount.setScale(2, RoundingMode.DOWN).toString());
params.put("currencyCode", "156");
params.put("payTimeout", "15");
params.put("backUrl", returnUrl);
params.put("payType", "A");
params.put("instMid", "ABC");
params.put("openId", "");
params.put("reserved", "");
// 构造签名
String sign = ABCPaymentUtils.generateSign(params, privateKey);
// 将签名加入请求参数
params.put("sign", sign);
// 发送请求
try {
HttpPost httpPost = new HttpPost(apiUrl);
httpPost.setEntity(new StringEntity(ABCPaymentUtils.buildQuery(params), ContentType.APPLICATION_FORM_URLENCODED));
CloseableHttpResponse response = httpClient.execute(httpPost);
String result = EntityUtils.toString(response.getEntity(), "UTF-8");
EntityUtils.consume(response.getEntity());
return result;
} catch (Exception e) {
throw new RuntimeException("支付请求发送失败", e);
}
}
}
```
3. 在Spring Boot的配置文件中配置支付服务的参数,例如:
```yaml
abc:
apiUrl: https://xxxxx
merchantId: 123456
terminalId: 123456
publicKey: xxxxx
privateKey: xxxxx
```
4. 在Spring Boot的Controller中调用支付服务,例如:
```java
@RestController
@RequestMapping("/payment")
public class PaymentController {
@Autowired
private ABCPaymentService paymentService;
@PostMapping("/abc")
public String abcPayment(@RequestParam String orderId,
@RequestParam BigDecimal amount,
@RequestParam String returnUrl) {
return paymentService.sendPaymentRequest(orderId, amount, returnUrl);
}
}
```
以上代码仅供参考,实际实现可能因具体业务场景而异。另外,请注意保护密钥信息的安全,不要将其硬编码在代码中,可以使用加密存储或配置中心等方式来保护。
