加密config（pem文件在resources下）
private Config getConfig() {

PrivateKey privateKey = getPrivateKey("wechatpay/apiclient_key.pem");
config = new RSAAutoCertificateConfig.Builder()
.merchantId(properties.getMch().getMchId())
.privateKey(privateKey)

.apiV3Key(properties.getMch().getApiV3Key())

解密config（pem文件在resources下）
public NotificationConfig getNotificationConfig() {
if(notificationConfig == null){
PrivateKey privateKey = getPrivateKey("wechatpay/apiclient_key.pem");
notificationConfig = new RSAAutoCertificateConfig.Builder()
.merchantId(properties.getMch().getMchId())

.build();
}
return notificationConfig;
}
***问题：
测试环境：用natapp内网穿透映射的回调地址，回调解密正常
生产环境：用nginx代理的回调地址，回调解密失败

实在没法了，我这边报错是这个一直报错的签名长度问题Last unit does not have enough valid bits有大佬解决下吗，搜了一下都说是微信什么故意发送的错误签名。。咋可能呢。我是才支付成功后回调报的这错，然后问了下Ai说是密钥错误，支付请求都完成了咋可能是密钥又错了
，实在没法啊。我升级支付包还是不行。。
