Java用HttpsURLConnection访问https网站的时候如何跳过SSL证书的验证？

static {
    try {
        trustAllHttpsCertificates();
        HttpsURLConnection.setDefaultHostnameVerifier
                (
                        (urlHostName, session) -> true
                );
    } catch (Exception e) {
    }
}

private static void trustAllHttpsCertificates()
        throws NoSuchAlgorithmException, KeyManagementException {
    TrustManager[] trustAllCerts = new TrustManager[1];
    trustAllCerts[0] = new TrustAllManager();
    SSLContext sc = SSLContext.getInstance("SSL");
    sc.init(null, trustAllCerts, null);
    HttpsURLConnection.setDefaultSSLSocketFactory(
            sc.getSocketFactory());
}

private static class TrustAllManager
        implements X509TrustManager {
    public X509Certificate[] getAcceptedIssuers() {
        return null;
    }

    public void checkServerTrusted(X509Certificate[] certs,
                                   String authType) {
    }

    public void checkClientTrusted(X509Certificate[] certs,
                                   String authType) {
    }
}
