为 SSLSocket 握手设置超时 [英] Placing timeout for SSLSocket handshake

问题描述

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，但有时会在引发异常之前达到约 1000 秒.在探索axis的内部实现后，我发现这是由于SSLSocket握手造成的.

Recently, I am having trouble with our SOAP calls which uses apache axis 1.4. I have set the timeout as 30s, however it sometimes reaches around ~1000s before throwing an exception. After exploring internal implementation of axis, I found out that it is due to the SSLSocket handshake.

请参阅下面的示例错误.

See sample error below.

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

是否可以在握手中设置超时?或者有没有别的办法强行切断连接.

Is it possible to put a timeout also on the handshake? Or is there another way to forcibly cut the connection.

另见代码中的握手部分

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

        ((SSLSocket) sslSocket).startHandshake();

推荐答案

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