微信商户批量转账

一、微信商户批量转账到零钱

1.引入库

代码如下（示例）：


/*** 微信支付专用类 请求操作方法** @author Administrator*/
public class WeChatNewUtil {private static Logger log = Logger.getLogger(WeChatNewUtil.class);public static String transferBatch="/v3/transfer/batches";public static String domain="https://api.mch.weixin.qq.com";public static int connectionTimeout=10000;public static int readTimeout=10000;public static String privatekeypath = ClassUtils.getDefaultClassLoader().getResource("").getPath()+"/weixin/apiclient_key.pem";//从微信商户平台下载的密钥存放的路径/*** 发起批量转账API 批量转账到零钱* @param url 全路径地址* @param requestJson 请求body* @param mchID4M 商户id* @param method 请求方法（get,post）* @param requestUrl (域名后面的请求url)* @return*/public static String postTransBatRequest(String url,String requestJson,String mchID,String method,String requestUrl) {CloseableHttpClient httpclient = HttpClients.createDefault();CloseableHttpResponse response = null;HttpEntity entity = null;try {String payserialNo= PemUtil.loadCertificate().getSerialNumber().toString(16).toUpperCase();//商户私钥证书HttpPost httpPost = new HttpPost(url);httpPost.addHeader("Content-Type", "application/json");httpPost.addHeader("Accept", "application/json");httpPost.addHeader("Wechatpay-Serial", payserialNo);//-------------------------核心认证 start-----------------------------------------------------------------String strToken = V3Util.getToken(method,requestUrl,requestJson,mchID,payserialNo, privatekeypath);// 添加认证信息httpPost.addHeader("Authorization","WECHATPAY2-SHA256-RSA2048" + " "+ strToken);//---------------------------核心认证 end---------------------------------------------------------------RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(readTimeout).setConnectTimeout(connectionTimeout).build();httpPost.setConfig(requestConfig);if(requestJson!=null)httpPost.setEntity(new StringEntity(requestJson, "UTF-8"));//发起转账请求response = httpclient.execute(httpPost);entity = response.getEntity();//获取返回的数据return EntityUtils.toString(entity);} catch (Exception e) {e.printStackTrace();} finally {// 关闭流}return null;}/*** get查询订单状态* @param url 全路径地址* @param requestJson 请求body* @param mchID4M 商户id* @param method 请求方法（get,post）* @param requestUrl (域名后面的请求url)* @return*/public static String getTransBatRequest(String url,String requestJson,String mchID,String method,String requestUrl) {CloseableHttpClient httpclient = HttpClients.createDefault();CloseableHttpResponse response = null;HttpEntity entity = null;try {String payserialNo= PemUtil.loadCertificate().getSerialNumber().toString(16).toUpperCase();//商户私钥证书HttpGet httpGet = new HttpGet(url);httpGet.addHeader("Content-Type", "application/json");httpGet.addHeader("Accept", "application/json");httpGet.addHeader("Wechatpay-Serial", payserialNo);//-------------------------核心认证 start-----------------------------------------------------------------String strToken = V3Util.getToken(method,requestUrl,requestJson,mchID,payserialNo, privatekeypath);// 添加认证信息httpGet.addHeader("Authorization","WECHATPAY2-SHA256-RSA2048" + " "+ strToken);//---------------------------核心认证 end---------------------------------------------------------------RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(readTimeout).setConnectTimeout(connectionTimeout).build();httpGet.setConfig(requestConfig);//发起转账请求response = httpclient.execute(httpGet);entity = response.getEntity();//获取返回的数据return EntityUtils.toString(entity);} catch (Exception e) {e.printStackTrace();} finally {// 关闭流}return null;}}

2.获取商户序列号密钥

代码如下（示例）：

 public class PemUtil {public static PrivateKey loadPrivateKey(String privateKey) {privateKey = privateKey.replace("-----BEGIN PRIVATE KEY-----", "").replace("-----END PRIVATE KEY-----", "").replaceAll("\\s+", "");try {KeyFactory kf = KeyFactory.getInstance("RSA");return kf.generatePrivate(new PKCS8EncodedKeySpec(new Base64().decode(privateKey)));} catch (NoSuchAlgorithmException e) {throw new RuntimeException("当前Java环境不支持RSA", e);} catch (InvalidKeySpecException e) {throw new RuntimeException("无效的密钥格式");}}public static PrivateKey loadPrivateKey() throws Exception {String certPath1 = ClassUtils.getDefaultClassLoader().getResource("").getPath()+"/weixin/apiclient_key.pem";//从微信商户平台下载的密钥存放的路径File file1 = new File(certPath1);InputStream inputStream = new FileInputStream(file1);ByteArrayOutputStream os = new ByteArrayOutputStream(2048);byte[] buffer = new byte[1024];String privateKey;try {for (int length; (length = inputStream.read(buffer)) != -1; ) {os.write(buffer, 0, length);}privateKey = os.toString("UTF-8");} catch (IOException e) {throw new IllegalArgumentException("无效的密钥", e);}return loadPrivateKey(privateKey);}public static X509Certificate loadCertificate() throws Exception {try {String certPath1 = ClassUtils.getDefaultClassLoader().getResource("").getPath()+"/weixin/apiclient_cert.pem";//从微信商户平台下载的序列号存放的路径File file1 = new File(certPath1);InputStream inputStream = new FileInputStream(file1);CertificateFactory cf = CertificateFactory.getInstance("X509");X509Certificate cert = (X509Certificate) cf.generateCertificate(inputStream);cert.checkValidity();return cert;} catch (CertificateExpiredException e) {throw new RuntimeException("证书已过期", e);} catch (CertificateNotYetValidException e) {throw new RuntimeException("证书尚未生效", e);} catch (CertificateException e) {throw new RuntimeException("无效的证书", e);}}private static final String TRANSFORMATION = "RSA/ECB/OAEPWithSHA-1AndMGF1Padding";public static String encryptOAEP(String message, X509Certificate certificate) throws Exception {return encrypt(message, certificate, TRANSFORMATION);}/*** 敏感信息加密*/public static String encrypt(String message, X509Certificate certificate, String transformation) throws Exception {try {Cipher cipher = Cipher.getInstance(transformation);cipher.init(Cipher.ENCRYPT_MODE, certificate.getPublicKey());byte[] data = message.getBytes(StandardCharsets.UTF_8);byte[] ciphertext = cipher.doFinal(data);return new Base64().encodeToString(ciphertext);} catch (NoSuchAlgorithmException | NoSuchPaddingException e) {throw new RuntimeException("当前Java环境不支持RSA v1.5/OAEP", e);} catch (InvalidKeyException e) {throw new IllegalArgumentException("无效的证书", e);} catch (IllegalBlockSizeException | BadPaddingException e) {throw new IllegalBlockSizeException("加密原串的长度不能超过214字节");}}}

2.获取签名

代码如下（示例）：

public class V3Util {private static Logger log = Logger.getLogger(V3Util.class);/*** * @param method 请求方法 post* @param canonicalUrl 请求地址* @param body 请求参数* @param merchantId 这里用的商户号* @param certSerialNo 商户证书序列号* @param keyPath 商户证书地址* @return* @throws Exception*/public static String getToken(String method,String canonicalUrl,String body,String merchantId,String certSerialNo,String keyPath) throws Exception {String signStr = "";//获取32位随机字符串String nonceStr = getRandomString(32);//当前系统运行时间long timestamp = System.currentTimeMillis() / 1000;if (StringUtils.isEmpty(body)) {body = "";}//签名操作String message = buildMessage(method, canonicalUrl, timestamp, nonceStr, body);//签名操作String signature = sign(message.getBytes("utf-8"), keyPath);//组装参数signStr = "mchid=\"" + merchantId + "\",timestamp=\"" +  timestamp+ "\",nonce_str=\"" + nonceStr+ "\",serial_no=\"" + certSerialNo + "\",signature=\"" + signature + "\"";return signStr;}public static String buildMessage(String method, String canonicalUrl, long timestamp, String nonceStr, String body) {return method + "\n" + canonicalUrl + "\n" + timestamp + "\n" + nonceStr + "\n" + body + "\n";}public static String sign(byte[] message, String keyPath) throws Exception {Signature sign = Signature.getInstance("SHA256withRSA");sign.initSign(getPrivateKey(keyPath));sign.update(message);return Base64.encodeBase64String(sign.sign());}/*** 微信支付-前端唤起支付参数-获取商户私钥** @param filename 私钥文件路径  (required)* @return 私钥对象* @throws Exception */public static PrivateKey getPrivateKey(String filename) throws Exception {return PemUtil.loadPrivateKey();}/*** 获取随机位数的字符串* @param length* @return*/public static String getRandomString(int length) {String base = "abcdefghijklmnopqrstuvwxyz0123456789";Random random = new Random();StringBuffer sb = new StringBuffer();for (int i = 0; i < length; i++) {int number = random.nextInt(base.length());sb.append(base.charAt(number));}return sb.toString();}
}

2.RFC3339日期转换

代码如下（示例）：

 public static String getDateByRFC3339(String time){DateTime dateTime = new DateTime(time);long timeInMillis = dateTime.toCalendar(Locale.getDefault()).getTimeInMillis();Date date = new Date(timeInMillis);SimpleDateFormat format = new SimpleDateFormat("yyyyMMddHHmmsss");String time = format.format(date);return time;}
