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;

}
