java配合uniapp的微信支付商户转账等解决方案 _微信支付

识字粗堪供赋役，不须辛苦慕公卿。这篇文章主要讲述java配合uniapp的微信支付商户转账等解决方案相关的知识，希望能为你提供帮助。
maven：

< dependency> < groupId> com.github.wxpay< /groupId> < artifactId> wxpay-sdk< /artifactId> < version> 0.0.3< /version> < /dependency>

java: 微信支付信息配置类：

public class MyWxpayConfigimplements WXPayConfig { private byte [] certData; public MyWxpayConfig() throwsException{ InputStream certStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("cert/apiclient_cert.p12"); this.certData = https://www.songbingjia.com/android/IOUtils.toByteArray(certStream); certStream.close(); }public static final String APP_ID = 应用ID;

public static final String APP_KEY = 支付key;

public static final String MCH_ID = 商户号;

public static final String BODY = 用户界面展示内容;

public static final String PARTNER_ID = "*******";

public static final String GRANT_TYPE = "client_credential";

public static String GATEURL = "https://api.mch.weixin.qq.com/pay/unifiedorder";

public static String NOTIFY_URL = 回调接口地址;

public static String ORDER_QUERY = "https://api.mch.weixin.qq.com/pay/orderquery";

@Override public String getAppID() { return APP_ID; }

@Override public String getMchID() { return MCH_ID; }

@Override public String getKey() { return APP_KEY; }

@Override public InputStream getCertStream() { return null; }

@Override public int getHttpConnectTimeoutMs() { return 8000; }

@Override public int getHttpReadTimeoutMs() { return 10000; } }

微信支付实现类：

@Service
public class WxPayServiceImpl implements WxPayService {

@Override public Map< String, String> dounifiedOrder(订单信息,IP地址) throws Exception { //本地订单信息操作略过 Map< String, String> fail = new HashMap< > (); MyWxpayConfig config = new MyWxpayConfig(); WXPay wxpay = new WXPay(config); Map< String, String> data = https://www.songbingjia.com/android/new HashMap< String, String> (); data.put("appid", MyWxpayConfig.APP_ID); data.put("mch_id", MyWxpayConfig.MCH_ID); data.put("nonce_str", WXPayUtil.generateNonceStr()); data.put("body", 用户界面信息); data.put("out_trade_no", UUID.randomUUID().toString().replaceAll("-", "")); data.put("total_fee", 订单金额); //String类型，以分为单位 data.put("spbill_create_ip", IP地址); data.put("notify_url", MyWxpayConfig.NOTIFY_URL); data.put("trade_type", "APP"); data.put("sign", WXPayUtil.generateSignature(data, MyWxpayConfig.APP_KEY)); Map< String,String> dataMap=new HashMap< String,String> (); Map< String,String> map = new HashMap< > (); try {Map< String, String> resp = wxpay.unifiedOrder(data); if("SUCCESS".equals(resp.get("result_code"))){ String nonce_str = (String)resp.get("nonce_str"); String prepay_id = (String)resp.get("prepay_id"); Long time =System.currentTimeMillis()/1000; map.put("appid",config.getAppID()); map.put("partnerid",config.getMchID()); map.put("package","Sign=WXPay"); map.put("noncestr",nonce_str); map.put("timestamp",time+""); map.put("prepayid",prepay_id); map.put("sign",sign); } resp.put("time",System.currentTimeMillis()/1000+""); return map; } catch (Exception e) {
fail.put("failMsg",e.toString());
return fail;
}
}
