本文实例为大家分享了java微信退款接口和支付宝退款接口的具体代码，供大家参考，具体内容如下

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

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;
 }
