try {
    KeyStore keystore = KeyStore.getInstance("PKCS12");
    char[] partnerId2charArray = this.getMchId().toCharArray();
    keystore.load((InputStream)inputStream, partnerId2charArray);
    this.sslContext = SSLContexts.custom().loadKeyMaterial(keystore, partnerId2charArray).build();
    var15 = this.sslContext;
} catch (Exception var10) {
    throw new WxPayException("证书文件有问题，请核实！", var10);
} finally {
    IOUtils.closeQuietly((InputStream)inputStream);
}

在

keystore.load((InputStream)inputStream, partnerId2charArray);

此行报错了, 提示证书文件有问题,这什么情况啊,按理说 文件获取到了,默认密码是商户id,应该没毛病的啊,是哪里还需要配置吗???请帮助,谢谢
