Producing messages

In all the samples presented in this chapter, we have sent orders through RESTful API for testing purposes. However, we may easily create some test data by defining the message source inside the application. Here's a bean that generates one message per second using @Poller and sends it to the output channel:

@Bean@InboundChannelAdapter(value = Source.OUTPUT, poller = @Poller(fixedDelay = "1000", maxMessagesPerPoll = "1"))public MessageSource<Order> ordersSource() {    Random r = new Random();    return () -> new GenericMessage<>(new Order(OrderStatus.NEW, (long) r.nextInt(5), Collections.singletonList((long) r.nextInt(10))));}
