新商户需要使用公钥模式，无需下载平台证书
// 可以根据实际情况使用publicKeyFromPath或publicKey加载公钥Config config =new RSAPublicKeyConfig.Builder().merchantId(merchantId).privateKeyFromPath(privateKeyPath).publicKeyFromPath(publicKeyPath).publicKeyId(publicKeyId).merchantSerialNumber(merchantSerialNumber).apiV3Key(apiV3Key).build();
