这个是完整的请求参数，商户号和批次号，我是从 service.listAvailableMerchants(listAvailableMerchantsRequest);这个结果里，获取的， // 查询可用商户 ListAvailableMerchantsRequest listAvailableMerchantsRequest = new ListAvailableMerchantsRequest(); listAvailableMerchantsRequest.setLimit(50); Integer listAvailableMerchantsOffset = 1; listAvailableMerchantsRequest.setStockId("19534288"); listAvailableMerchantsRequest.setStockCreatorMchid("1659714450"); AvailableMerchantCollection availableMerchantCollection = null; try { listAvailableMerchantsRequest.setOffset(listAvailableMerchantsOffset); availableMerchantCollection = service.listAvailableMerchants(listAvailableMerchantsRequest); System.out.println(availableMerchantCollection); } catch (Exception e) { throw new RuntimeException(e); }更新：你offset没有按要求传，所以报错了
看起来应该是你接口请求的时候参数出现问题了，可以打印日志比对或者也可以复制参数到postman验证，我测试查询是ok的
