Java 小程序V3支付 apiv3 后端代码实现与工具
以下是使用Spring Boot和APIv2密钥发起JSAPI支付的示例代码:
1. 首先,您需要引入微信支付相关的依赖,具体依赖版本可以根据您的需求选择:
```xml
<dependency>
<groupId>com.github.wxpay.sdk</groupId>
<artifactId>wxpay-sdk</artifactId>
<version>3.0.9</version>
</dependency>
```
2. 创建一个支付服务类,用于处理支付相关的请求和响应:
```java
@Service
public class WechatPayService {
@Autowired
private WxPayService wxPayService;
/**
* 发起JSAPI支付请求
* @param request
* @return
* @throws Exception
*/
public Map<String, String> jsapiPay(JsapiPayRequest request) throws Exception {
WxPayUnifiedOrderRequest unifiedOrderRequest = new WxPayUnifiedOrderRequest();
unifiedOrderRequest.setBody(request.getBody());
unifiedOrderRequest.setOutTradeNo(request.getOutTradeNo());
unifiedOrderRequest.setTotalFee(BaseWxPayRequest.yuanToFen(request.getTotalFee()));
unifiedOrderRequest.setSpbillCreateIp(request.getSpbillCreateIp());
unifiedOrderRequest.setNotifyUrl(request.getNotifyUrl());
unifiedOrderRequest.setTradeType("JSAPI");
unifiedOrderRequest.setOpenid(request.getOpenid());
return wxPayService.createOrder(unifiedOrderRequest);
}
/**
* 处理支付回调通知
* @param xmlData
* @return
* @throws Exception
*/
public String notify(String xmlData) throws Exception {
WxPayOrderNotifyResult notifyResult = wxPayService.parseOrderNotifyResult(xmlData);
// 进行订单状态的处理
// ...
return "<xml><return_code><![CDATA[SUCCESS]]></return_code><return_msg><![CDATA[OK]]></return_msg></xml>";
}
}
```
3. 创建一个控制器类,用于处理支付请求和回调通知:
```java
@RestController
public class WechatPayController {
@Autowired
private WechatPayService wechatPayService;
/**
* 发起JSAPI支付请求
* @param request
* @return
* @throws Exception
*/
@PostMapping("/jsapi/pay")
public Map<String, String> jsapiPay(@RequestBody JsapiPayRequest request) throws Exception {
return wechatPayService.jsapiPay(request);
}
/**
* 处理支付回调通知
* @param request
* @return
* @throws Exception
*/
@PostMapping("/notify")
public String notify(HttpServletRequest request) throws Exception {
BufferedReader reader = request.getReader();
StringBuffer buffer = new StringBuffer();
String line;
while ((line = reader.readLine()) != null) {
buffer.append(line);
}
reader.close();
return wechatPayService.notify(buffer.toString());
}
}
```
4. 创建一个JSAPI支付请求的实体类:
```java
public class JsapiPayRequest {
private String body; // 商品描述
private String outTradeNo; // 商户订单号
private String totalFee; // 标价金额(单位:元)
private String spbillCreateIp; // 终端IP
private String notifyUrl; // 通知地址
private String openid; // 用户标识
// 省略getter和setter方法
}
```
5. 在配置文件中添加微信支付相关的配置:
```properties
# 微信支付配置
wxpay.appId=应用ID
wxpay.mchId=商户号
wxpay.key=APIv2密钥
wxpay.certPath=证书路径
wxpay.notifyUrl=支付回调通知地址
```
6. 创建一个微信支付服务的配置类:
```java
@Configuration
public class WechatPayConfig {
@Value("${wxpay.appId}")
private String appId;
@Value("${wxpay.mchId}")
private String mchId;
@Value("${wxpay.key}")
private String key;
@Value("${wxpay.certPath}")
private String certPath;
@Value("${wxpay.notifyUrl}")
private String notifyUrl;
@Bean
public WxPayService wxPayService() throws Exception {
WxPayConfig wxPayConfig = new WxPayConfig();
wxPayConfig.setAppId(appId);
wxPayConfig.setMchId(mchId);
wxPayConfig.setKey(key);
wxPayConfig.setCertPath(certPath);
wxPayConfig.setNotifyUrl(notifyUrl);
return new WxPayServiceImpl(wxPayConfig);
}
}
```
到这里,您就可以使用APIv2密钥发起JSAPI支付了。
