     * @param orderId 商户的订单号
     * @param tradeNo 支付宝的交易流水号
     * @param totalAmount 退款金额
     * @return
     */
    public static Map alipayCreateOrderRefund(String orderId,String tradeNo,String totalAmount) {
        Map map = new LinkedHashMap();

        AlipayClient alipayClient = new DefaultAlipayClient(AlipayConfig. aliPayUrl,
                AlipayConfig.appId, AlipayConfig.developerSpoon,
                "json", AlipayConfig.input_charset, AlipayConfig.aliPaySpoon, "RSA2");
        AlipayTradeRefundRequest request = new AlipayTradeRefundRequest();

        AlipayTradeRefundModel model= new AlipayTradeRefundModel();
        model.setOutTradeNo(orderId);//订单支付时传入的商户订单号
        model.setTradeNo(tradeNo);//支付宝交易号
        model.setRefundAmount(totalAmount);//refund_amount    需要退款的金额，该金额不能大于订单金额,单位为元

        request.setBizModel(model);//请求参数

        AlipayTradeRefundResponse  response=null;
        try {
            response = alipayClient.execute(request);
            System.out.println(JSONObject.fromObject(response).toString());
            Map tuiMap=JSONObject.fromObject(response);

        }catch ( AlipayApiException e){
            String massage = "alipay.trade.refund退款接口：订单签名错误";
            System.out.println(massage);
        }
        if(response.isSuccess()){
            System.out.println("调用成功");
            map.put("status", 0);//订单退款  status：0 成功 1:失败
            logger.info("支付宝：支付订单支付结果查询：订单out_trade_no----"+orderId+"---订单退款成功！");
        } else {
            System.out.println("调用失败");
            map.put("status",1);//订单退款  status：0 成功 1:失败
            logger.info("支付宝：支付订单支付结果查询：订单out_trade_no----"+orderId+"---订单退款失败！");
        }
        return map;
    }
