下单报错The corresponding provider for the merchant already exists. 错误原因我大概清楚，是上一次获取的证书还存在. 但是我是多台服务器，A服务器正常获取Config，也做了null判断，null就获取，非空就继续用，代码 if (config == null){ config = new RSAAutoCertificateConfig.Builder() .merchantId(mchid) .privateKey(privateKey) .merchantSerialNumber(merchantSerialNumber) .apiV3Key(apiV3key) .build(); } A服务器正常，请求分配到B服务器就报错The corresponding provider for the merchant already exists.
