支付接口接入

String url=profileHttpUrl+"/aliPay/notifyApp";
            Orders orders = ordersJpaRepository.getOne(ordersId);
            String outTradeNo=orders.getOrderNum();
            //构造client
            CertAlipayRequest certAlipayRequest   =   new   CertAlipayRequest ();
            //设置网关地址
            certAlipayRequest . setServerUrl ( "https://openapi.alipay.com/gateway.do" );
            //设置应用Id
            certAlipayRequest . setAppId ( commonRepository.findOne(63).getValue() );
            //设置应用私钥
            certAlipayRequest . setPrivateKey ( commonRepository.findOne(65).getValue() );
            //设置请求格式，固定值json
            certAlipayRequest . setFormat ( "json" );
            //设置字符集
            certAlipayRequest . setCharset ( "UTF-8" );
            //设置签名类型
            certAlipayRequest . setSignType ( "RSA2" );
            //设置应用公钥证书路径
            certAlipayRequest . setCertPath ( classPath+app_cert_path );
            //设置支付宝公钥证书路径
            certAlipayRequest . setAlipayPublicCertPath (  classPath+alipay_cert_path);
            //设置支付宝根证书路径
            certAlipayRequest . setRootCertPath ( classPath+alipay_root_cert_path );
            //构造client
            AlipayClient   alipayClient   =   new   DefaultAlipayClient ( certAlipayRequest);
            //实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称：alipay.trade.app.pay
            AlipayTradeAppPayRequest   request   =   new   AlipayTradeAppPayRequest ();
            //SDK已经封装掉了公共参数，这里只需要传入业务参数。以下方法为sdk的model入参方式(model和biz_content同时存在的情况下取biz_content)。
            AlipayTradeAppPayModel   model   =   new   AlipayTradeAppPayModel ();
            model . setBody ( Config.BASE_NAME );
            model . setSubject ( Config.BASE_NAME );
            model . setOutTradeNo ( outTradeNo );
            model . setTimeoutExpress ( "30m" );
            model . setTotalAmount ( orders.getPayMoney()+"");
            model . setProductCode ( "QUICK_MSECURITY_PAY" );
            request . setBizModel ( model );
            request . setNotifyUrl ( url );
            try  {
                //这里和普通的接口调用不同，使用的是sdkExecute
                AlipayTradeAppPayResponse   response   =   alipayClient . sdkExecute ( request );
                if(response.isSuccess()){
                    System.out.println();
                    return ResultUtil.success(response.getBody());
                } else {
                    log.info("调用失败");
                    ResultUtil.error(-100,"获取订单失败！");
                }
                System . out . println ( response . getBody ()); //就是orderString 可以直接给客户端请求，无需再做处理。
            }  catch  ( AlipayApiException   e ) {
                e . printStackTrace ();
            }

支付之后回调函数

public void notifyApp(HttpServletRequest request, HttpServletResponse response){
            //获取支付宝POST过来反馈信息
            Map<String,String> params = new HashMap<String,String>();
            Map requestParams = request.getParameterMap();
            for (Iterator iter = requestParams.keySet().iterator(); iter.hasNext();) {
                String name = (String) iter.next();
                String[] values = (String[]) requestParams.get(name);
                String valueStr = "";
                for (int i = 0; i < values.length; i++) {
                    valueStr = (i == values.length - 1) ? valueStr + values[i]
                            : valueStr + values[i] + ",";
                }
                //乱码解决，这段代码在出现乱码时使用。
                //valueStr = new String(valueStr.getBytes("ISO-8859-1"), "utf-8");
                params.put(name, valueStr);
            }
            //切记alipaypublickey是支付宝的公钥，请去open.alipay.com对应应用下查看。
            //boolean AlipaySignature.rsaCheckV1(Map<String, String> params, String publicKey, String charset, String sign_type)
            try {
                log.info("回调成功！！！");
                boolean flag = AlipaySignature.rsaCertCheckV1(params, classPath+alipay_cert_path,
                        AliPayConstants.CHARSET,"RSA2");
                log.info(flag+"回调验证信息");
                if(flag){
                    String outTradeNo = params.get("out_trade_no");
                    //支付成功，处理业务
                    Orders orders = ordersService.findByOrderNum(outTradeNo);
                    orders.setPayWay(2); //支付方式为2支付宝
                    orders.setStatus(2); //已付款
                    orders.setPayTime(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date())); //设置支付时间
                   // if(orders.getPinkId()>0){
                   //     GoodsPink storePink = goodsPinkRepository.findOrderById(orders.getOrderNum(),orders.getPinkId());
                   //     if(storePink !=null){
                   //         storePink.setIsRefund(0);
                   //         goodsPinkJpaRepository.saveAndFlush(storePink);
                   //     }
                   // }
                   // orders.setCanUse(orders.getPayMoney());
                    ordersService.updateBody(orders);
                    //订单分销
                 //   ordersService.fenXiao(orders.getId());
                }
            } catch (AlipayApiException e) {
                e.printStackTrace();
                log.info("回调验证失败！！！");
            }
        }

订单退款

public boolean refund(Long ordersId) {
            try {
                Orders orders = ordersJpaRepository.getOne(ordersId);
              // AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do", commonRepository.findOne(63).getValue(),

                certAlipayRequest . setCertPath ( classPath+app_cert_path );
                //设置支付宝公钥证书路径
                certAlipayRequest . setAlipayPublicCertPath (  classPath+alipay_cert_path);
                //设置支付宝根证书路径
                certAlipayRequest . setRootCertPath ( classPath+alipay_root_cert_path );

                model.setOutTradeNo(orders.getOrderNum()); //订单号

                request.setBizModel(model);
                AlipayTradeRefundResponse response = alipayClient.certificateExecute(request);
