WECHAT_PAY_CERTIFICATE_SERIAL_NUMBER和MERCHANT_CERTIFICATE_SERIAL_NUMBER 分别代表什么意思

<dependency> <groupId>com.github.wechatpay-apiv3</groupId> <artifactId>wechatpay-java</artifactId> <version>0.2.9</version> </dependency> 依据官方给的依赖包，以及实例代码，发现存在问题，现在不知道该怎么处理。 [图片] Config config = new RSAAutoCertificateConfig.Builder() .merchantId(merchantId) .privateKeyFromPath(privateKeyPath) .merchantSerialNumber(merchantSerialNumber) .apiV3Key(apiV3key) .build(); PrivacyEncryptor encryptor = config.createEncryptor(); String wechatPayCertificateSerialNumber = encryptor.getWechatpaySerial(); 此处的证书序列号是由config 获取的。 而config的初始化由必须先给 证书序列号 ，这不是前后矛盾了？ 证书序列号如果可以为null ，那么初始化时候假设能成功，那么 证书序列号 有什么用？ 如果是必填，为撒由是在初始化以后才可以获取到。 假设可以填null ，也支持后面获取。那么是否应该有一个set 操作? 而且官方给的这个证书序列号获取的代码的返回值的类型也是错误的。 [图片] 此处写的返回类型是 PrivateEncryptor， 实际上就没这个类。真正的返回类是 PrivacyEncryptor 如何获取微信支付平台证书的证书序列号？
