Spring integration 在Spring TCP集成时，在TcpOutboundGateway等待响应异常时超时

目前，我正在通过Spring integration TCP进行外部供应商集成，通过创建不同的@ServiceActivator以实现唯一的IP/端口组合，将IP 1、端口1、端口2、端口3和端口1、端口2和端口3发送到不同的端口

在正常的消息加载中，一切都正常工作，但是，当我将负载增加到40-50个事务/秒时，通过等待响应，我看到消息超时

下面是其中一个Service Activator，其他也以类似的方式设置。如果我的主ip不可用，我将使用FailoverClient ConnectionFactory进行故障切换。我还使用了CachingClientConnectionFactory，这样，我的每个请求都不必创建昂贵的连接

@Bean
@ServiceActivator(inputChannel = "toRequest")
public MessageHandler serviceActivatorOne() {
    TcpOutboundGateway tcpOutputGateway = new TcpOutboundGateway();
    List<ServerNode> nodes = properties.getFailOver().getServers().subList(0,2);
    tcpOutputGateway.setConnectionFactory(createFailOverConnectionFactory(nodes));
    tcpOutputGateway.setReplyChannelName("bytesToObjectChannel");
    tcpOutputGateway.setRemoteTimeout(5000);
    return tcpOutputGateway;
}

...
...

private AbstractClientConnectionFactory createFailOverConnectionFactory(List<ServerNode> serverNodeList) {
        FailoverClientConnectionFactory connectionFactory =
                new FailoverClientConnectionFactory(createConnectionFactories(serverNodeList));
        connectionFactory.setSingleUse(true);
        connectionFactory.afterPropertiesSet();
        return connectionFactory;
    }

private AbstractClientConnectionFactory createDefaultConnectionFactory(String url, int port, String name) {
        TcpNetClientConnectionFactory connFactory = new TcpNetClientConnectionFactory(url, port);
        connFactory.setSerializer(byteArrayLengthHeaderSerializer());
        connFactory.setDeserializer(byteArrayLengthHeaderSerializer());
        connFactory.setSoTimeout(properties.getSocketTimeOut());
        connFactory.setSoKeepAlive(true);
        connFactory.setLookupHost(false);
        connFactory.setComponentName(name);
        connFactory.setSingleUse(true);

        if(properties.getPoolMaxSize() <= 0) {
            return connFactory;
        } else {
            CachingClientConnectionFactory cachingConnFactory =
                    new CachingClientConnectionFactory(connFactory, properties.getPoolMaxSize());
            cachingConnFactory.setConnectionWaitTimeout(properties.getPoolMaxWait());
            return cachingConnFactory;
        }
    }

我试图从TCP上的Spring参考中找出一些细节，但到目前为止没有成功。我没有使用共享套接字，因为setSingleUse设置为false。任何帮助/线索都将不胜感激

看起来您连接的服务器在重载情况下无法及时响应5秒超时

似乎默认的remoteTimeout是10秒，我将其设置为5秒，似乎服务器无法在5秒内响应。我可以调整remoteTimeout并进行检查。您是否有任何建议，我可以在哪里更改任何spring tcp集成设置，或者这完全取决于服务器的响应速度慢

对，它确实依赖于服务器。我想象有一种情况，当有一些巨大的负载时，即使是10秒钟也不够。您应该咨询您的服务器供应商以确定其吞吐量。

但您的问题是什么？看起来您连接的服务器在重载情况下无法及时响应5秒超时。谢谢。我的问题是为什么在重载情况下会发生超时，但我明白你的意思。似乎默认的remoteTimeout是10秒，我将其设置为5秒，似乎服务器无法在5秒内响应。我可以调整remoteTimeout并进行检查。您是否有任何建议，我可以在哪里更改任何spring tcp集成设置，或者这完全取决于服务器的响应速度慢？是的，这确实取决于服务器。我想象有一种情况，当有一些巨大的负载时，即使是10秒钟也不够。您应该咨询服务器供应商以确定其吞吐量
