为 SSLSocket 握手设置超时

Question

最近，我在使用 Apache 轴 1.4 的 SOAP 调用时遇到了问题。我已将超时设置为 30 秒，但有时会在抛出异常之前达到约 1000 秒。探索axis的内部实现，发现是SSLSocket握手的原因。

请参阅下面的示例错误。

java.net.SocketException: Connection timed out (Read failed)

是否可以在握手时也设置超时？或者有没有其他方法可以强行断开连接。

另外，查看代码中的握手部分

 sslSocket = sslFactory.createSocket(tunnel, host, port, true);
            if (log.isDebugEnabled()) {
                log.debug(Messages.getMessage("setupTunnel00",
                          tcp.getProxyHost(),
                        "" + tunnelPort));
            }
        }

        ((SSLSocket) sslSocket).startHandshake();

当您创建tunnel 时，调用：

tunnel.connect(new InetSocketAddress(host, port), 30000);
