Question

如果使用相同的主机和端口创建多个TCP出站端点会发生什么，两个端点将使用相同的套接字，即连接或不同的连接。如何在mule测试流程中获取套接字对象。

我在这里使用2个具有相同地址和端口的端点，需要验证两者是否使用相同的连接或不同的连接。

<flow name="testOutBoundTCP">
     <inbound-endpoint ref="outer" />
     <outbound-endpoint ref = "clientEndpoint2"/>
     <logger message="2 : #[message.payload]" category="INFO"></logger>
     <test:component appendString=" Received" logMessageDetails="true"/>
    </flow>

    <flow name="testOutBoundTCP1">
     <inbound-endpoint ref="outer1" />
     <outbound-endpoint ref = "clientEndpoint"/>
     <logger message="1 : #[message.payload]" category="INFO"></logger>
     <test:component appendString=" Received" logMessageDetails="true" />
    </flow>


    <flow name="testComponent">
        <inbound-endpoint ref="clientEndpoint" />
        <test:component/>
    </flow>

我知道这有点晚了，如果您的工作流程是同步的，您可以使用＆＃34;请求 - 响应＆＃34;在TCP端点中。如果您的工作流程需要异步并且仍然需要使用相同的套接字，那么您可以通过在tcp-connector中为入站和出站tcp端点添加服务覆盖来实现此目的，并从端点引用这些连接器。

<tcp:connector name="TCP_Inbound" doc:name="TCP connector"
        clientSoTimeout="${client.so.timeout}" receiveBacklog="0"
        receiveBufferSize="0" sendBufferSize="0"
        serverSoTimeout="${server.so.timeout}" socketSoLinger="0"
        validateConnections="true" keepAlive="true">
        <reconnect-forever />
        <service-overrides messageReceiver="custom.TCPMessageReceiver" />

    </tcp:connector>
    <tcp:connector name="TCP_Outbound" doc:name="TCP connector"
        clientSoTimeout="${client.so.timeout}" receiveBacklog="0"
        receiveBufferSize="0" sendBufferSize="0"
        serverSoTimeout="${server.so.timeout}" socketSoLinger="0"
        validateConnections="true" keepAlive="true">
        <reconnect-forever />
        <service-overrides dispatcherFactory="custom.TcpDispatcherFactory" />

    </tcp:connector>

在receiver部分中，服务覆盖类应扩展TcpMessageReceiver类，您可以覆盖以下方法将客户端套接字添加到mule会话。

/* (non-Javadoc)
         * @see org.mule.transport.tcp.TcpMessageReceiver.TcpWorker#preRouteMuleMessage(org.mule.api.MuleMessage)
         * This class shares the socket object to be used by the outbound endpoint.
         */
        @Override
        protected void preRouteMuleMessage(final MuleMessage message) throws Exception
        {
            super.preRouteMuleMessage(message);

            final SocketAddress clientAddress = socket.getRemoteSocketAddress();
            if (clientAddress != null)
            {
                message.setOutboundProperty(MuleProperties.MULE_REMOTE_CLIENT_ADDRESS, clientAddress.toString());
            }

            message.setOutboundProperty("ClientSocket", socket );     
        }

现在您可以引用Outbound属性＆＃34; ClientSocket＆＃34;在您的muleflow中，使用调度程序将其传递回出站TCP。在dispatcher部分中，您必须具有DispatcherFactory类的服务覆盖，该类应扩展AbstractMessageDispatcher类并覆盖doDispatch方法，如下所示：

protected synchronized void doDispatch(MuleEvent event) throws Exception
    {     
        /* Get the socket shared from the inbound endpoint receiver class */    
        Socket socket = (Socket) event.getMessage().getSessionProperty("Socket");           
        dispatchToSocket(socket,event);
    }
