    1、首先设置支付宝账户有关信息及返回路径

    /**说明: *以下代码只是为了方便商户测试而提供的样例代码,商户可以根据自己网站的需要,按照技术文档编写,并非一定要使用该代码。 *该代码仅供学习和研究支付宝接口使用,只是提供一个参考。 */ public class AlipayConfig { //↓↓↓↓↓↓↓↓↓↓请在这里配置您的基本信息↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓ //合作身份者ID,签约账号,以2088开头由16位纯数字组成的字符串,查看地址:https://openhome.alipay.com/platform/keyManage.htm?keyType=partner public static String partner = "2**************1"; //商户的私钥,需要PKCS8格式,RSA公私钥生成:https://doc.open.alipay.com/doc2/detail.htm?spm=a219a.7629140.0.0.nBDxfy&treeId=58&articleId=103242&docType=1 public static String private_key = "*************="; //支付宝的公钥,查看地址:https://openhome.alipay.com/platform/keyManage.htm?keyType=partner public static String alipay_public_key = "*********"; // 签名方式 public static String sign_type = "RSA"; // 调试用,创建TXT日志文件夹路径,见AlipayCore.java类中的logResult(String sWord)打印方法。 public static String log_path ="C://"; // 字符编码格式 目前支持 gbk 或 utf-8 public static String input_charset = "utf-8"; // 接收通知的接口名 public static String service = "http://60.***.***.00/callbacks.do"; //public static String service = "mobile.securitypay.pay"; //APPID public static String app_id="2016**********12"; //↑↑↑↑↑↑↑↑↑↑请在这里配置您的基本信息↑↑↑↑↑↑↑↑↑↑↑↑↑↑↑ } 1234567891011121314151617181920212223242526272829303132333435

    2、支付宝APP支付–申请支付请求参数

    [申请支付请求参数说明] (https://doc.open.alipay.com/docs/doc.htm?spm=a219a.7629140.0.0.O57CIo&treeId=193&articleId=105465&docType=1)

    @ResponseBody @RequestMapping(value = "/alipay.do", produces = "text/html;charset=UTF-8",method={RequestMethod.GET}) public static String alipay(String body, String subject, String out_trade_no, String total_amount) throws Exception { //公共参数 Map<String, String> map = new HashMap<String, String>(); map.put("app_id", AlipayConfig.app_id); map.put("method", "alipay.trade.app.pay"); map.put("format", "json"); map.put("charset", "utf-8"); map.put("sign_type", "RSA"); map.put("timestamp", UtilDate.getDateFormatter()); map.put("version", "1.0"); map.put("notify_url", AlipayConfig.service); Map<String, String> m = new HashMap<String, String>(); m.put("body", body); m.put("subject", subject); m.put("out_trade_no", out_trade_no); m.put("timeout_express", "30m"); m.put("total_amount", total_amount); m.put("seller_id", AlipayConfig.partner); m.put("product_code", "QUICK_MSECURITY_PAY"); JSONObject bizcontentJson= JSONObject.fromObject(m); map.put("biz_content", bizcontentJson.toString()); //对未签名原始字符串进行签名 String rsaSign = AlipaySignature.rsaSign(map, AlipayConfig.private_key, "utf-8"); Map<String, String> map4 = new HashMap<String, String>(); map4.put("app_id", AlipayConfig.app_id); map4.put("method", "alipay.trade.app.pay"); map4.put("format", "json"); map4.put("charset", "utf-8"); map4.put("sign_type", "RSA"); map4.put("timestamp", URLEncoder.encode(UtilDate.getDateFormatter(),"UTF-8")); map4.put("version", "1.0"); map4.put("notify_url", URLEncoder.encode(AlipayConfig.service,"UTF-8")); //最后对请求字符串的所有一级value(biz_content作为一个value)进行encode,编码格式按请求串中的charset为准,没传charset按UTF-8处理 map4.put("biz_content", URLEncoder.encode(bizcontentJson.toString(), "UTF-8")); Map par = AlipayCore.paraFilter(map4); //除去数组中的空值和签名参数 String json4 = AlipayCore.createLinkString(map4); //拼接后的字符串 json4=json4 + "&sign=" + URLEncoder.encode(rsaSign, "UTF-8"); System.out.println(json4.toString()); AliPayMsg apm = new AliPayMsg(); apm.setCode("1"); apm.setMsg("支付成功"); apm.setData(json4.toString()); JSONObject json = JSONObject.fromObject(apm); System.out.println(json.toString()); return json.toString(); }

    3、支付宝支付结果异步通知业务处理

    @ResponseBody @RequestMapping(value = "/callbacks.do", produces = "text/html;charset=UTF-8",method={RequestMethod.POST}) public String callbacks( HttpServletRequest request ) throws Exception { //接收支付宝返回的请求参数 Map requestParams = request.getParameterMap(); JSONObject json = JSONObject.fromObject(requestParams); String trade_status = json.get("trade_status").toString().substring(2,json.get("trade_status").toString().length()-2); String out_trade_no = json.get("out_trade_no").toString().substring(2,json.get("out_trade_no").toString().length()-2); String notify_id = json.get("notify_id").toString().substring(2,json.get("notify_id").toString().length()-2); System.out.println("===================================================="); System.out.println(json.toString()); System.out.println("支付宝回调地址!"); System.out.println("商户的订单编号:" + out_trade_no); System.out.println("支付的状态:" + trade_status); if(trade_status.equals("TRADE_SUCCESS")) { /** *支付成功之后的业务处理 */ return "SUCCESS"; } }else { /** *支付失败后的业务处理 */ return "SUCCESS"; } return "SUCCESS"; }
