我的通用未来：

public class MyGenericFutureListener implements GenericFutureListener<DefaultPromise<Channel>> {
SslHandler sslHandler;
String crlPath;

public MyGenericFutureListener(SslHandler sslHandler, String crlPath) {
    this.sslHandler = sslHandler;
    this.crlPath = crlPath;
}

@Override
public void operationComplete(DefaultPromise<Channel> channelFuture) throws Exception {
    if (channelFuture.isSuccess()) {
        SSLSession sslSession = sslHandler.engine().getSession();
        X509Certificate cert = (X509Certificate) sslSession.getPeerCertificates()[0];
        if (isCertificateRevoked(cert)) {
            log.error("Certificate revoked");
            //channelFuture.get().close();
        }
    }
}


@SneakyThrows
private boolean isCertificateRevoked(X509Certificate cert) {
    X509CRL crl = (X509CRL) CertificateFactory.getInstance("X.509").generateCRL(new FileInputStream(crlPath));
    return crl.isRevoked(cert);
}
