jetty7 同时并发连接多个目的主机时(100+) 本地tcp端口不够用的解决方案,技术点滴,通讯+多线程...-优快云博客

当使用Jetty7进行并发连接时遇到本地TCP端口资源耗尽的问题，可以通过修改注册表来扩展MaxUserPort的可用端口数量，并调整TcpTimedWaitDelay的值以缩短等待时间。参考链接提供了详细的解决步骤和相关技术资料。

第一种方法

改注册表

改变这个变量：MaxUserPort可用端口数量由1024扩展为65535

改变这个变量:TcpTimedWaitDelay 把它缩短到30s

//先站个位置

public void startConnection( HttpDestination destination )
        throws IOException
    {
        SocketChannel channel = null;
        try
        {
            channel = SocketChannel.open();
            Address address = destination.isProxied() ? destination.getProxy() : destination.getAddress();
            channel.socket().setTcpNoDelay(true);
            channel.socket().setReuseAddress(true);
            channel.socket().setSoLinger(true, 0);
            if (_httpClient.isConnectBlocking())
            {
                channel.socket().connect(address.toSocketAddress(), _httpClient.getConnectTimeout());
                channel.configureBlocking(false);
                _selectorManager.register( channel, destination );
            }
            else
            {
                channel.configureBlocking(false);
                channel.connect(address.toSocketAddress());
                _selectorManager.register(channel,destination);
                ConnectTimeout connectTimeout = new ConnectTimeout(channel,destination);
                _httpClient.schedule(connectTimeout,_httpClient.getConnectTimeout());
                _connectingChannels.put(channel,connectTimeout);
            }
        }
