Spring Boot 2.5，Java 15 Java HttpClient或Apache HttpClient，检查目标证书的CN

Question

是否可以提交一个String值来检查（如果它等于）目标证书的CN（String值）

我用

HttpRequest request = HttpRequest.newBuilder()
    .POST(HttpRequest.BodyPublishers.ofString(body))
    .uri(URI.create("https://<ip-address>/..."))
    .timeout(Duration.ofMillis(1000))
    .build();

HttpResponse<String> response;
try {
    response = HttpClient.newBuilder()
        .version(Version.HTTP_1_1)
        .authenticator(this.authenticator)
        .build()
        .send(request, HttpResponse.BodyHandlers.ofString());
} catch (InterruptedException iex) {
} catch (IOException ioex) {
}

或者，如果无法提交，可能可以定义或设置一个方法，从目标证书读取CN，并对照另一个字符串值检查该值

具有HttpsURLConnection的一种解决方案是：

    HostnameVerifier myHostnameVerifier = new HostnameVerifier() {
        public boolean verify(String hostname, SSLSession session) {
            // check what ever, example CN from certificat
            Certificate[] peerCertificates = session.getPeerCertificates();
            Certificate peerCertificate = peerCertificates[0];
            ...
            return <true> or <false>;
        }
    }
    
    HttpsURLConnection con = (HttpsURLConnection)url.openConnection(); 
    con.setHostnameVerifier(myHostnameVerifier);

使用HttpsURLConnection意味着使用OutputStream和InputStream，这是一种老式风格

JavaHttpClient或Apache HttpClient也可以这样做吗？ 我必须并行运行许多连接
