java版微信和支付宝退款接口

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

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;
 
 }
