在Java中有如下方式支持配置TLS的版本：
方式一：

        System.setProperty("https.protocols", "TLSv1");
        System.setProperty("jdk.tls.client.protocols", "TLSv1");

方式二：

                HttpsURLConnection connection = (HttpsURLConnection) this.url.openConnection();
                SSLContext sc = SSLContext.getInstance("TLSv1.2"); 
                sc.init(null, null, new java.security.SecureRandom());
                connection.setSSLSocketFactory(sc.getSocketFactory());
                logger.info("---SSLContext sc " + sc.getProtocol());

注意：如果当前进程中有一个地方已经按照方式一设置了之后，那么其他地方再通过方式二设置将不会生效；如果不设置TLS的版本号，客户端可能得到如下连接被重置的报错，eg:
