微信代金券发放，可以给其他主体的小程序用户发券吗？ 发券时用我司的商户号， appid用其他其他公司的小程序appid（其他主体），这种可以发券吗？

以下是配置HttpClient代码 private static CloseableHttpClient init() { try { PrivateKey privateKey = PemUtil.loadPrivateKey( new ByteArrayInputStream(merchantPrivateKey.getBytes(StandardCharsets.UTF_8))); CertificatesManager certificatesManager = CertificatesManager.getInstance(); certificatesManager.putMerchant(merchantId, new WechatPay2Credentials(merchantId, new PrivateKeySigner(merchantSerialNumber, privateKey)), apiV3Key.getBytes(StandardCharsets.UTF_8)); verifier = certificatesManager.getVerifier(merchantId); //... CloseableHttpClient httpClient = WechatPayHttpClientBuilder.create() .withMerchant(merchantId, merchantSerialNumber, privateKey) .withValidator(new WechatPay2Validator(verifier)) .evictExpiredConnections() // 开启回收空闲线程 .evictIdleConnections(3L, TimeUnit.SECONDS) // 30秒回收空闲连接 .setMaxConnPerRoute(300).setMaxConnTotal(1000) .build(); return httpClient; } catch (Exception e) { e.printStackTrace(); } return null; } 以下是调用api接口代码 private static <T extends WechatBaseResponse> T execute(String url, Object params, boolean isPost, Class<T> tClass) { long startTime = System.currentTimeMillis(); String message = JsonUtils.toJsonString(params); T t = null; try { HttpUriRequest request; if (isPost) { HttpPost httpPost = new HttpPost(url); httpPost.addHeader("Accept", "application/json"); httpPost.addHeader("Content-type", "application/json; charset=utf-8"); httpPost.setEntity(new StringEntity(JsonUtils.toJsonString(params), "utf-8")); request = httpPost; } else { HttpGet httpGet = new HttpGet(url); httpGet.addHeader("Accept", "application/json"); request = httpGet; } CloseableHttpResponse response = httpClient.execute(request); String result = EntityUtils.toString(response.getEntity()); t = JsonUtils.parseObject(result, tClass); logger.info("【微信】请求 url={} 请求参数={} 响应数据={} 处理时间={}ms", url, message, result, System.currentTimeMillis() - startTime); } catch (IOException e) { logger.error("【微信】调用异常 url={} 请求参数={}", url, message, e); try { t = tClass.newInstance(); t.setCode(CodeEnum.ERROR.getCode()); t.setMessage(CodeEnum.ERROR.getMsg()); } catch (Exception ex) { } } return t; } 在并发高的时候"处理时间"能有十几秒, 这个问题怎么解决? 是我配置有问题, 还是哪里有问题?
