maven:

  <dependency>

      <artifactId>wxpay-sdk</artifactId>
      <version>0.0.3</version>
  </dependency>

java:

微信支付信息配置类:

public class MyWxpayConfig  implements WXPayConfig {
    private byte [] certData;

    public MyWxpayConfig() throws  Exception{
        InputStream certStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("cert/apiclient_cert.p12");
        this.certData = 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 = 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;
     }
  }

 

微信商户转账到个人实现类

                try {
                    keyStore.load(instream, MyWxpayConfig.MCH_ID.toCharArray());
                } finally {
                    instream.close();
                }
                SSLContext sslcontext = SSLContexts.custom().loadKeyMaterial(keyStore, MyWxpayConfig.MCH_ID.toCharArray()).build();

                HttpPost httppost = new HttpPost("https://api.mch.weixin.qq.com/mmpaymkttransfers/promotion/transfers");
                httppost.addHeader("Content-Type", "text/xml");
                StringEntity se = new StringEntity(xml, "UTF-8");
                httppost.setEntity(se);
                CloseableHttpResponse responseEntry = httpclient.execute(httppost);
                try {
                    HttpEntity entity = responseEntry.getEntity();

                        Element rootElt = document.getRootElement();
                        String resultCode = rootElt.elementText("result_code");
                        if (resultCode.equals("SUCCESS")) {
                            tansferStatus=true;

uniapp调起微信支付

that.$myRequest({
      url: ‘/Pay/wxOrder‘,
      methods: ‘post‘,
      data: { 订单信息 },
      })
    .then(res
=> { uni.requestPayment({   provider: ‘wxpay‘, orderInfo: 后台返回的微信支付参数, success: (e) => {
          成功后的操作
        }, fail: (e) => {
          失败后的操作    }, complete: ()
=> {
          完成后的操作         }        })     }).
