java实现网站微信扫码支付

发布日期： 2026-01-12 阅读量： 作者： 用户投稿

一、网站微信扫码支付开发并没有现成的java示例,总结一下自己微信扫码支付心得

二、首先去微信公众平台申请账户

https://mp.weixin.qq.com
**

三、账户开通、开发者认证之后就可以进行微信支付开发了

1、微信统一下单接口调用获取预支付id，以及生成二维码所需的codeUrl

/**
 * 保存订单，并生成二维码所需的codeUrl
 * 
 * @param request
 * @param response
 * @param notifyURLBuf
 * @param order
 * @return
 * @throws Exception
 */
 @Override
 public Map<String, String> getWechatOrderInfo(String ip, Cuser user, String notifyUrl, Order order) throws Exception {
 Map<String, String> resultMap = new HashMap<String, String>();
 // 生成并保存订单
 order.setUserId(user.getId());
 // 支付方式 0：银联 1：支付宝 2：网上银行 3：微信 4：其他
 order.setPayType("3");
 // 生成订单号
 order.setOrderNo(OrderNoGenerator.getOrderNo());
 // 订单类型 1：消费 2：退款
 order.setOrderType("1");
 // 订单创建时间
 order.setCreateTime(new Date());
 // 订单更新时间
 order.setUpdateTime(new Date());
 // 订单状态 0: 交易中 1：完成 2：已取消
 order.setOrderStatus("0");
 // 付款状态 0：失败 1:成功 2、待付款
 order.setPayStatus("2");
 // 设置订单失效时间
 Calendar calendar = Calendar.getInstance();
 calendar.add(Calendar.HOUR, 2);
 order.setExpireTime(calendar.getTime());
 Integer orderId = this.balanceDao.saveOrder(order);

 Map<String, String> payPreIdMap = new HashMap<>();
 payPreIdMap = WechatUtil.getPayPreId(String.valueOf(orderId), "体检报告", notifyUrl, ip,
  String.valueOf((order.getMoney().multiply(new BigDecimal(100)).intValue())), orderId.toString());
 String prePayId = payPreIdMap.get("prepay_id");
 // 更新
 order.setId(orderId);
 order.setPrepayId(prePayId);
 order.setCodeUrl(payPreIdMap.get("code_url"));
 this.balanceDao.updateOrder(order);
 // return WechatUtil.QRfromGoogle(order.getCodeUrl(), 300, 0);
 resultMap.put("codeUrl", order.getCodeUrl());
 resultMap.put("orderId", String.valueOf(order.getId()));
 return resultMap;
 }

此方法返回的数据如下

<xml><return_code><![CDATA[SUCCESS]]></return_code>
<return_msg><![CDATA[OK]]></return_msg>
<appid><![CDATA[wxaf0b*****8afbf]]></appid>
<mch_id><![CDATA[1408****02]]></mch_id>
<nonce_str><![CDATA[zf0vGvdtVycBliwB]]></nonce_str>
<sign><![CDATA[A2910F16086211153D747058063B3368]]></sign>
<result_code><![CDATA[SUCCESS]]></result_code>
<prepay_id><![CDATA[wx201701191109388037e9a12310276591827]]></prepay_id>
<trade_type><![CDATA[NATIVE]]></trade_type>
<code_url><![CDATA[weixin://wxpay/bizpayurl?pr=1UjorNX]]></code_url>
</xml>

2、服务器端接受微信支付结果通知

/**
  * 保存微信通知结果
  * 
  * @param request
  * @param response
  * @return
  * @throws Exception
  */
 @Override
 public String saveWechatNotify(String notifyInfoXml) throws Exception {
  Map<String, String> noticeMap = XMLUtil.doXMLParse(notifyInfoXml);
  // 这个其实是订单 的id
  String outTradeNo = noticeMap.get("out_trade_no");
  Order order = this.balanceDao.getOrderById(Integer.valueOf(outTradeNo));
  // 如果支付通知信息不为，说明请求已经处理过，直接返回
  if (StringUtil.isNotEmpty(order.getNotifyInfo())) {
   return "SUCCESS";
  }
  String sign = noticeMap.get("sign");
  noticeMap.remove("sign");
  // 验签通过
  if (WechatUtil.getSignVeryfy(noticeMap, sign)) {
   // 通信成功此字段是通信标识，非交易标识，交易是否成功需要查看result_code来判断
   if ("SUCCESS".equals(noticeMap.get("return_code"))) {
    // 交易成功
    if ("SUCCESS".equals(noticeMap.get("result_code"))) {
     // 商户订单号

     // 订单更新时间
     order.setUpdateTime(new Date());
     // ------------------------------
     // 处理业务开始
     // ------------------------------
     // 是否交易成功,1:成功0：失败
     // 微信支付成功
     order.setPayStatus("1");
     // 订单状态 0: 交易中 1：完成 2：已取消
     order.setOrderStatus("1");
     // 保存通知信息
     order.setNotifyInfo(notifyInfoXml);
     this.balanceDao.updateOrder(order);
     // 处理业务完毕
    } else {
     // 错误时，返回结果未签名，记录retcode、retmsg看失败详情。
     logger.info("查询验证签名失败或业务错误");
     logger.info("retcode:" + noticeMap.get("retcode") + " retmsg:" + noticeMap.get("retmsg"));
    }
    return "SUCCESS";
   } else {
    logger.info("后台调用通信失败");
   }
   return "SUCCESS";
  } else {
   logger.info("通知签名验证失败");
  }
  return null;
 }

4、下面是用到的配置类

package com.caifu.tencent.common;

/**
 * User: rizenguo
 * Date: 2014/10/29
 * Time: 14:40
 * 这里放置各种配置数据
 */
public class Configure {
//这个就是自己要保管好的私有Key了（切记只能放在自己的后台代码里，不能放在任何可能被看到源代码的客户端程序中）
 // 每次自己Post数据给API的时候都要用这个key来对所有字段进行签名，生成的签名会放在Sign这个字段，API收到Post数据的时候也会用同样的签名算法对Post过来的数据进行签名和验证
 // 收到API的返回的时候也要用这个key来对返回的数据算下签名，跟API的Sign数据进行比较，如果值不一致，有可能数据被第三方给篡改

 private static String key = "A6gB0Dy4dsfdssuPCPsdfdshkSCDQcr3eXS";


 private static String appSecret="7584sdfdsfe4f26fadsfsdfs56f10728a";

 //微信分配的公众号ID（开通公众号之后可以获取到）
 private static String appID = "wxaf0b86sdfsdf8afbf";

 //微信支付分配的商户号ID（开通公众号的微信支付功能之后可以获取到）
 private static String mchID = "14012313702";

 //受理模式下给子商户分配的子商户号
 private static String subMchID = "";

 //HTTPS证书的本地路径
 private static String certLocalPath = "";

 //HTTPS证书密码，默认密码等于商户号MCHID
 private static String certPassword = "";

 //是否使用异步线程的方式来上报API测速，默认为异步模式
 private static boolean useThreadToDoReport = true;

 //机器IP
 private static String ip = "";

 //以下是几个API的路径：
 //1）被扫支付API
 public static String UNIFIEDORDER_API = "https://api.mch.weixin.qq.com/pay/unifiedorder";

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

 //2）被扫支付查询API
 public static String PAY_QUERY_API = "https://api.mch.weixin.qq.d/pay/orderquery";

 //3）退款API
 public static String REFUND_API = "https://api.mch.weixin.qq.com/secapi/pay/refund";

 //4）退款查询API
 public static String REFUND_QUERY_API = "https://api.mch.weixin.qq.com/pay/refundquery";

 //5）撤销API
 public static String REVERSE_API = "https://api.mch.weixin.qq.com/secapi/pay/reverse";

 //6）下载对账单API
 public static String DOWNLOAD_BILL_API = "https://api.mch.weixin.qq.com/pay/downloadbill";

 //7) 统计上报API
 public static String REPORT_API = "https://api.mch.weixin.qq.com/payitil/report";

 public static boolean isUseThreadToDoReport() {
  return useThreadToDoReport;
 }

 public static void setUseThreadToDoReport(boolean useThreadToDoReport) {
  Configure.useThreadToDoReport = useThreadToDoReport;
 }

 public static String HttpsRequestClassName = "com.tencent.common.HttpsRequest";

 public static void setKey(String key) {
  Configure.key = key;
 }

 public static void setAppID(String appID) {
  Configure.appID = appID;
 }

 public static void setMchID(String mchID) {
  Configure.mchID = mchID;
 }

 public static void setSubMchID(String subMchID) {
  Configure.subMchID = subMchID;
 }

 public static void setCertLocalPath(String certLocalPath) {
  Configure.certLocalPath = certLocalPath;
 }

 public static void setCertPassword(String certPassword) {
  Configure.certPassword = certPassword;
 }

 public static void setIp(String ip) {
  Configure.ip = ip;
 }

 public static String getKey(){
  return key;
 }

 public static String getAppid(){
  return appID;
 }

 public static String getMchid(){
  return mchID;
 }

 public static String getSubMchid(){
  return subMchID;
 }

 public static String getCertLocalPath(){
  return certLocalPath;
 }

 public static String getCertPassword(){
  return certPassword;
 }

 public static String getIP(){
  return ip;
 }

 public static void setHttpsRequestClassName(String name){
  HttpsRequestClassName = name;
 }

}

在这里需要注意的配置
private static String key = “A6gB0Dy4dsfdssuPCPsdfdshkSCDQcr3eXS”;
这里的key 是登陆https://pay.weixin.qq.com/index.php/core/info (微信商户平台)设置的api_key

   }
  }

  return sb.toString();
 }

 /**
  * 将requestxml通知结果转出啊成map

  */
 public static Map<String, String> parseXml(HttpServletRequest request) throws Exception {
  // 解析结果存储在HashMap
  Map<String, String> map = new HashMap<String, String>();
  InputStream inputStream = request.getInputStream();
  // 读取输入流
  SAXReader reader = new SAXReader();
  org.dom4j.Document document = reader.read(inputStream);

   map.put(e.getName(), e.getText());
  // 释放资源
  inputStream.close();
  inputStream = null;
  return map;
 }

}

6、整个后台服务已经完成，最后关闭页面微信支付二维码，告知用户支付已经完成了

var f;
 /* 定时任务方法，异步请求去查询订单是否支付*/
 function GetOrder() {
  var orderId = $('#orderId').val();
  if (orderId != '') {
   $.ajax({
    url : "${base}/balance/auth/isPay?orderId=" + orderId,
    type : "GET",
    async : false,
    success : function(d) {
     if (d == "1") {
      //当获取到微信支付结果时，关闭二维码div
      $(".weixinpay").css("display", "none");
      $("#zhichutankuang").css("display", "block");
      ////当获取到微信支付结果时，关闭定时任务
      clearInterval(f);
      // layer.alert('付款成功', {
      // skin : 'layui-layer-molv', // 样式类名
      // closeBtn : 0
      // }, function() {
      // location.href = "${base}/balance/auth/presentation?tjNo=" + $("#tjNo").val();
      // });

     }
    }
   });
  }
 }
 //异步请求获取生成二维码的url
 $(".paylast").click(function() {
  var $payType = $('input:radio:checked').val();
  var $money = $("#money").val();
  var $tjReportType = $("#tjReportType").val();
  var $tjNo = $("#tjNo").val();
  $.ajax({
   url : "${base}/balance/auth/wechatInfo",
   type : "POST",
   async : false,
   data : {
    payType : $payType,
    money : $money,
    tjNo : $tjNo,
    tjReportType : $tjReportType
   },
   success : function(d) {
    if (d.resultCode == "1000") {
     //当请求成功时，设置二维码图片地址
     $("#codeImg").attr('src', d.obj);
     $("#orderId").val(d.attributes.orderId);
     ////当请求成功时，启动定时任务,每隔3秒去后台查询一次订单是否成功
     f = setInterval(GetOrder, 3000);
     // GetOrder(true);
    }
   }
  });
  $(".selpaycon").css("display", "none");
  $(".weixinpay").css("display", "block");
 });
