我的代碼假設與某個對等方啟動 SSL 套接字，提取證書并關閉套接字。問題是，createSocket()似乎阻塞了很長時間。如何設置合理的超時時間？這是我的完整代碼：public static void main(String[] args) throws Exception {        SSLContext sslCtx;        sslCtx = SSLContext.getInstance("TLSv1.2");        sslCtx.init(null, new TrustManager[]{new X509TrustManager() {            private X509Certificate[] accepted;            @Override            public void checkClientTrusted(X509Certificate[] xcs, String string) {            }            @Override            public void checkServerTrusted(X509Certificate[] xcs, String string) {                accepted = xcs;            }            @Override            public X509Certificate[] getAcceptedIssuers() {                return accepted;            }        }}, null);        System.out.println("start ....");        try (SSLSocket sslSocket = (SSLSocket) sslCtx.getSocketFactory().createSocket("156.70.54.68", 443)) {            sslSocket.setSoTimeout(5_000);            Certificate[] certificates = sslSocket.getSession().getPeerCertificates();            System.out.println(certificates.length);        } catch (Exception e) {            System.out.println(e);        }    }
