Java微信支付宝分账指南

本文将详细介绍如何使用Java代码实现微信和支付宝分账功能，以及实现自定义分账规则和查询分账结果。

一、微信支付分账

微信支付分账是指商户将订单的资金分给多个分账接收方。常用于分润、提成、佣金等场景。

下面是Java实现微信支付分账的代码：

public static String profitSharing(String appId, String mchId, String nonceStr, String sign, String signType,
        String partnerTradeNo, String openId, String amount, String desc) throws Exception {
    Map params = new HashMap<>();
    params.put("appId", appId);
    params.put("mchId", mchId);
    params.put("nonceStr", nonceStr);
    params.put("sign", sign);
    params.put("signType", signType);
    params.put("partnerTradeNo", partnerTradeNo);
    params.put("openid", openId);
    params.put("amount", amount);
    params.put("description", desc);

    String response = HttpUtil.post(WxPayConstants.ProfitSharingUrl, buildXml(params));

    Map result = WxPaySignature.checkIsSignValidFromResponseString(response, signType, config.getKey());

    return result.get("return_code");
}

二、支付宝分账

支付宝分账是指商户将订单的资金分给多个分账接收方。常用于分润、提成、佣金等场景。

下面是Java实现支付宝分账的代码：

public static AlipayFundTransToaccountTransferResponse transfer(String appId, String privateKey, String publicKey,
        String outBizNo, String payeeAccount, String amount, String remark) throws AlipayApiException {
    AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do", appId, privateKey,
            "json", "UTF-8", publicKey, "RSA2");
    AlipayFundTransToaccountTransferRequest request = new AlipayFundTransToaccountTransferRequest();
    request.setBizContent("{\"out_biz_no\":\"" + outBizNo + "\","
            + "\"payee_type\":\"ALIPAY_LOGONID\",\"payee_account\":\"" + payeeAccount + "\","
            + "\"amount\":\"" + amount + "\",\"payer_show_name\":\"XXX\",\"payee_real_name\":\"XXX\","
            + "\"remark\":\"" + remark + "\"}");
    AlipayFundTransToaccountTransferResponse response = alipayClient.execute(request);

    return response;
}

三、自定义分账规则

在实际应用中，需要根据具体业务需求来设置分账规则。比如不同的分账接收方分到不同的金额、比例等。

下面是Java实现自定义分账规则的代码：

public static String profitSharing(String appId, String mchId, String nonceStr, String sign, String signType,
        String partnerTradeNo, Map receivers, String totalAmount, String desc) throws Exception {
    Map params = new HashMap<>();
    params.put("appId", appId);
    params.put("mchId", mchId);
    params.put("nonceStr", nonceStr);
    params.put("sign", sign);
    params.put("signType", signType);
    params.put("partnerTradeNo", partnerTradeNo);
    params.put("receivers", receivers);
    params.put("totalAmount", totalAmount);
    params.put("description", desc);

    String response = HttpUtil.post(WxPayConstants.ProfitSharingUrl, buildXml(params));

    Map result = WxPaySignature.checkIsSignValidFromResponseString(response, signType, config.getKey());

    return result.get("return_code");
}

四、查询分账结果

为了保证分账的准确性和及时性，商户需要及时查询分账结果。以下是Java实现查询分账结果的代码：

public static String queryProfitSharing(String appId, String mchId, String nonceStr, String sign, String signType,
        String outTradeNo) throws Exception {
    Map params = new HashMap<>();
    params.put("appId", appId);
    params.put("mchId", mchId);
    params.put("nonceStr", nonceStr);
    params.put("sign", sign);
    params.put("signType", signType);
    params.put("outTradeNo", outTradeNo);

    String response = HttpUtil.post(WxPayConstants.ProfitSharingQueryUrl, buildXml(params));

    Map result = WxPaySignature.checkIsSignValidFromResponseString(response, signType, config.getKey());

    return result.get("result_code");
}
