1、微信退款接口

相对来说我感觉微信的退款接口还是比较好调用的，直接发送httppost请求即可；

/**
         * 
         * 微信退款
         * @param transaction_id 微信支付订单号
         * @param out_refund_no  商户订单号
         * @param total_fee 总金额
         * @param refund_fee 退款金额
         * @param op_user_id 操作人
         * @return String
         * @exception
         */
        public String wxPayRefundRequest(String transaction_id, String out_refund_no,
                int total_fee, int refund_fee, String op_user_id) {
            CloseableHttpClient httpclient = null;
            CloseableHttpResponse response = null;
            String strResponse = null;
            try {
                httpclient = ClientCustomSSL.getCloseableHttpClient();
                // 构造HTTP请求
                HttpPost httpPost = new HttpPost(Configure.PAY_REFUND_API);
                // PayRefundReqData wxdata = new PayRefundReqData(
                // "1004720096201602263541023415", "16371", 30, 30, "19417");
                PayRefundReqData wxdata = new PayRefundReqData(transaction_id,
                        out_refund_no, total_fee, refund_fee, op_user_id);
                String requestStr = Util.ConvertObj2Xml(wxdata);
                StringEntity se = new StringEntity(requestStr.toString());
                httpPost.setEntity(se);
                // 发送请求
                response = httpclient.execute(httpPost);
    
                HttpEntity entity = response.getEntity();
                if (entity != null) {
                    SAXReader saxReader = new SAXReader();
                    Document document = saxReader.read(entity.getContent());
                    Element rootElt = document.getRootElement();
                    // 结果码
                    String returnCode = rootElt.elementText("return_code");
                    String resultCode = rootElt.elementText("result_code");
                    if ("SUCCESS".equals(returnCode)&&"SUCCESS".equals(resultCode)) {
                        strResponse=returnCode;
                    }else {
                        strResponse=rootElt.elementText("err_code_des");
                    }
                }
                 EntityUtils.consume(entity); 
            } catch (Exception e) {
                Logger.getLogger(getClass()).error("payRefundRequest", e);
            } finally {
                try {
                    response.close();
                    httpclient.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    Logger.getLogger(getClass()).error("payRefundRequest关闭异常:", e);
                }
            }
            return strResponse;
        }

报错的话请检查加密的sign是否正确，还有就是调用的接口地址是否正确  
2、支付宝退款接口    
支付宝直接导入支付宝封装好的jar包直接调用即可，官网下载地址: [https://doc.open.alipay.com/doc2/detail?treeId=54&articleId=103419&docType=1][https_doc.open.alipay.com_doc2_detail_treeId_54_articleId_103419_docType_1]

调用方法:

/**
         * 
         *  支付宝退款请求
         * @param out_trade_no 订单支付时传入的商户订单号,不能和 trade_no同时为空。
         * @param trade_no 支付宝交易号，和商户订单号不能同时为空
         * @param refund_amount 需要退款的金额，该金额不能大于订单金额,单位为元，支持两位小数
         * @return 
         * String
         * @exception 
         */
        public String alipayRefundRequest(String out_trade_no,String trade_no,double refund_amount){
    
            // 发送请求
            String strResponse = null;
            try {
                AlipayClient alipayClient = new DefaultAlipayClient
                        (AlipayConfig.alipayurl,AlipayConfig.appid,
                                AlipayConfig.private_key,AlipayConfig.content_type,AlipayConfig.input_charset,AlipayConfig.ali_public_key);
                AlipayTradeRefundRequest request = new AlipayTradeRefundRequest();
                AlipayRefundInfo alidata= new AlipayRefundInfo();
                alidata.setOut_trade_no(out_trade_no);
                alidata.setRefund_amount(refund_amount);
                alidata.setTrade_no(trade_no);
                request.setBizContent(JsonUtils.convertToString(alidata));
                AlipayTradeRefundResponse response = alipayClient.execute(request);
                strResponse=response.getCode();
                if ("10000".equals(response.getCode())) {
                    strResponse="退款成功";
                }else {
                    strResponse=response.getSubMsg();
                }
            } catch (Exception e) {
                Logger.getLogger(getClass()).error("alipayRefundRequest", e);
            }
            return strResponse;
    
        }
