How to send reply for TCP requests (spring-integration)?

I would need something similar like in Can not send response for UDP message but for TCP. So the client send message and TCP server can send back response like OK. For TCP socket-expression="@inbound.socket" and destination-expression="headers['ip_packetAddress']" cannot be used.

This is how my config look like now: 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:int="http://www.springframework.org/schema/integration"
    xmlns:int-ip="http://www.springframework.org/schema/integration/ip"
    xmlns:int-event="http://www.springframework.org/schema/integration/ip"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/integration http://www.springframework.org/schema/integration/spring-integration.xsd
        http://www.springframework.org/schema/integration/ip http://www.springframework.org/schema/integration/ip/spring-integration-ip.xsd">

  <int:channel id="tcpSend"/>

  <int-ip:tcp-connection-factory id="client" type="client"/>

  <int-ip:tcp-connection-factory id="server" type="server" host="localhost" port="1234"/>

  <int-ip:tcp-outbound-channel-adapter id="tcpOutbound" channel="tcpSend"
                                   connection-factory="client"/>

  <int-ip:tcp-inbound-channel-adapter id="tcpInbound" channel="tcpReceive"
                                  connection-factory="server"/>

  <int:service-activator id="tcpHandler" input-channel="tcpReceive" output-channel="tcpSend"
                         ref="listener"/>
</beans>

In case of TCP it is much easier because you can use Inbound Gateway.

The sample on the matter is in the official repository: https://github.com/spring-projects/spring-integration-samples/tree/master/basic/tcp-client-server
