Como a empresa não pôde solicitar a permissão de serviço de pagamento do provedor de serviços, finalmente encontrou uma solução de provedor de serviços de shopping.
Você só pode encomendar produtos de um comerciante ao fazer um pedido no shopping. Isso ocorre porque o pedido de produtos de um comerciante exige pagamento combinado e o negócio não foi ativado. Portanto, a única desvantagem é que você só pode comprar produtos de uma loja de cada vez. Compras entre lojas não são suportadas.

}8. Solicitação de parcelamento de contas. Existem dois tipos de solicitação: parcelamento único e solicitação de parcelamento múltiplo.
Diferença: Após a solicitação de parcelamento único, nenhum outro parcelamento será permitido. O dinheiro restante a ser parcelado será descongelado diretamente para o lojista.
Solicitação de parcelamento múltiplo as divisões podem ser divididas várias vezes. A divisão máxima é O valor não pode exceder a proporção máxima de divisão. Após a conclusão da divisão, você deve solicitar o descongelamento para a parte da conta dividida, e o valor restante da divisão será descongelado para o comerciante.
Solicitar os resultados da divisão para uma única divisão requer chamar a interface de consulta de divisão.
1. Solicite uma única divisão de contas
public synchronized void profitSharing(Order order) {
//BigDecimal amount = order.getAmount();
SxzBreakfastShop shop = shopMapper.selectById(order.getShopId());
//BigDecimal wxRate = shop.getWxRate();//得除以100
//BigDecimal fyRate = shop.getFyRate();//得除以100
//BigDecimal wxMoney = amount.multiply(wxRate);
//BigDecimal fenzhangMoney = amount.multiply(new BigDecimal(1).subtract(wxRate));
//BigDecimal fymoney = fenzhangMoney.multiply(fyRate);
BigDecimal multiply = order.getCommission().multiply(new BigDecimal(100));
String s = WxPayKit.generateStr();//分账单号
//查询商户信息
List<ReceiverModel> list = new ArrayList<>();
list.add(ReceiverModel.builder()
.type("MERCHANT_ID")
.account(wxPayBean.getMchId())
.amount(multiply.intValue())
.description(shop.getName()+" 分账")
.build());
Map<String, String> params = ProfitSharingModel.builder()
.mch_id(wxPayBean.getMchId())
.sub_mch_id(shop.getSubMchid())
.appid(wxPayBean.getAppId())
.nonce_str(WxPayKit.generateStr())
.transaction_id(order.getPayNo())
.out_order_no(s)
.receivers(JSON.toJSONString(list))
.build()
.createSign(wxPayBean.getPartnerKey(), SignType.HMACSHA256);
String result = WxPayApi.multiProfitSharing(params, wxPayBean.getCertPath(), wxPayBean.getMchId());
System.out.println(result);
Map<String, String> map = WxPayKit.xmlToMap(result);
if("SUCCESS".equals(map.get("return_code"))&&"SUCCESS".equals(map.get("result_code"))){
String order_id = map.get("order_id");//微信分账单号
String out_order_no = map.get("out_order_no");//商户分账单号
String transaction_id = map.get("transaction_id");//微信订单号
String status = map.get("status");//分账单状态
order.setFyNo(s);
//order.setCommission(multiply);
//order.setWxCommission(wxMoney);
if("PROCESSING".equals(status)){
order.setFyFlag("2");
this.baseMapper.updateById(order);
}else if("FINISHED".equals(status)){
order.setFyFlag("3");
order.setFzTime(new Date());
this.baseMapper.updateById(order);
saveFzToShopLog(order);//解冻
saveFzLog(order);//分账
}
}else{
saveFzFailLog(order);
throw new MyException(result);
}
}2. Para consultar os resultados do razão, é melhor escrever um cronômetro para consulta.
public synchronized void profitSharingQuery(Order order) {
SxzBreakfastShop shop = shopMapper.selectById(order.getShopId());
Map<String, String> params = ProfitSharingModel.builder()
.mch_id(wxPayBean.getMchId())
.sub_mch_id(shop.getSubMchid())
.appid(wxPayBean.getAppId())
.nonce_str(WxPayKit.generateStr())
.transaction_id(order.getPayNo())
.out_order_no(order.getFyNo())
.build()
.createSign(wxPayBean.getPartnerKey(), SignType.HMACSHA256);
String result = WxPayApi.profitSharingQuery(params);
System.out.println(result);
Map<String, String> map = WxPayKit.xmlToMap(result);
if("SUCCESS".equals(map.get("return_code"))&&"SUCCESS".equals(map.get("result_code"))){
String status = map.get("status");//分账单状态
if("FINISHED".equals(status)){
if(!"3".equals(order.getFyFlag())){
order.setFyFlag("3");
order.setFzTime(new Date());
this.baseMapper.updateById(order);
saveFzToShopLog(order);//解冻
saveFzLog(order);//分账
}
}
}else{
throw new MyException(result);
}
}Não vou escrever para divisões múltiplas. É basicamente o mesmo que divisão única. Basta montar os parâmetros.
