What is the java config equivalent to tcp-outbound

I have the following spring-integration XML config

<ip:tcp-outbound-gateway id="outboundClient"
        request-channel="requestChannel"
        reply-channel="string2ObjectChannel"
        connection-factory="clientConnectionFactory"
        request-timeout="10000"
        reply-timeout="10000"/>

How can I write the Java config equivalent of the above? I thought the equivalent would be

@Bean
public TcpOutboundGateway outboundClient() {
    TcpOutboundGateway tcpOutboundGateway = new TcpOutboundGateway();
    tcpOutboundGateway.setConnectionFactory(clientConnectionFactory());
    tcpOutboundGateway.setRequiresReply(true);
    tcpOutboundGateway.setReplyChannel(string2ObjectChannel());
    tcpOutboundGateway.setRequestTimeout(10000);
    tcpOutboundGateway.setSendTimeout(10000);
    return tcpOutboundGateway;
}

But I couldn't find a way to set the request channel. Any help would be appreciated.

Thank you

Your config looks good, but you should know in addition that any Spring Integration Consumer component consists of two main objects: MessageHandler (TcpOutboundGateway in your case) and EventDrivenConsumer for subscriable input-channel or PollingConsumer if input-channel is Pollable.

So, since you already have the first, handling, part you need another consuming. For this purpose Spring Integration suggests to mark your @Bean with endpoint annotations:

@Bean
@ServiceActivator(inputChannel = "requestChannel")
public TcpOutboundGateway outboundClient() {

See more in the Spring Integration Reference Manual.

However to allow such a annotation process (or any other Spring Integration infrastructure) you have to mark your @Configuration with @EnableIntegration.

Also consider to use Spring Integration Java DSL to have more gain from JavaConfig.
