1. 采用api版本：

com.github.wechatpay-apiv3wechatpay-java0.2.17

2.配置采用微信公钥模式

public Config getMerchantConfig(){
    Config config = new RSAPublicKeyConfig.Builder()
            .merchantId(merchantConfig.getString("merchantId"))
            .privateKeyFromPath(merchantConfig.getString("privateKeyFromPath"))
            .publicKeyFromPath(merchantConfig.getString("publicKeyPath"))
            .publicKeyId(merchantConfig.getString("publicKeyId"))
            .merchantSerialNumber(merchantConfig.getString("merchantSerialNumber"))
            .apiV3Key(merchantConfig.getString("apiV3Key"))
            .build();
    return config;

3.响应验签时报错：

我的问题是：

1. 我用微信公钥模式配置发起请求，响应应该返回微信公钥的Wechatpay-Serial，但为什么返回的Wechatpay-Serial序列号却是微信证书的。
2. 怎么才能让微信响应返回微信公钥的序列号？
