The problem is exactly what the message says.

Dispatcher has no subscribers for channel 'app-name:local:9010.inputChannel'.

You have no subscriber on this bean

@Bean
public MessageChannel inputChannel() {
    return new DirectChannel();
}

EDIT

@ServiceActivator(inputChannel = "inputChannel")
public void handle(String in) {
    ...
}

or

@Transformer(inputChannel = "inputChannel", outputChannel = "transformed")
public String handle(String in) {
    retur in.toUpperCase();
}

@ServiceActivator(inputChannel = "transformed")
public void handle(String in) {
    ...
}
