How to create an asynchronous singleton socket server with spring-integration?

I want to achieve the following using spring-integration: having a singleton open socket that constantly receives and writes data, asyncrhon!

This means I have to open a socket that constantly reads from the single socket, dispatches each message for async processing, and return the responses over the socket also async.

How can I achieve that asynchron pattern?

Especially: how can I use Serializer/Deserializer? As far as I understood, a serializer is only invoked on a new socket connection, so in my case only once at start of the first message?

@Configuration
public class SocketConfig {
    @Bean
    public TcpConnectionFactoryFactoryBean tcpFactory(MyConverter converter) {
        TcpConnectionFactoryFactoryBean fact = new TcpConnectionFactoryFactoryBean();
        fact.setType("server");
        fact.setPort(PORT);
        fact.setUsingNio(true); //should I use true or false?
        fact.setSingleUse(false); //keep socket constantly open
        fact.setSerializer(converter);
        fact.setDeserializer(converter);
        return fact;
    }

    @Bean
    public TcpInboundGateway serverGateway(
            @Qualifier("tcpFactory") TcpConnectionFactoryFactoryBean factory,
            @Qualifier("serverChannel") MessageChannel serverChannel) throws Exception {
        TcpInboundGateway g = new TcpInboundGateway();
        g.setConnectionFactory(factory.getObject());
        g.setRequestChannel(serverChannel);
        return g;
    }

}

@MessageEndpoint
public class SocketEndpoint {

    @ServiceActivator(inputChannel = "serverChannel")
    public Object run(Object obj) {

    }
}


@Service
public class MyConverter implements Serializer<Object>, Deserializer<Object> {
    //read from socket
    @Override
    public Object deserialize(InputStream inputStream) {
    }

    //send back to socket
    @Override
    public void serialize(Object message, OutputStream outputStream) {
    }
}
