What is the java config equivalent to tcp-outbound-gateway?

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
