I am trying to use Spring Integration (3.0.1) to implement a RESTful service that supports both XML and JSON as request and response formats, using a int-http:inbound-gateway.
My code is based on the Spring integration example (although this does not use the message payload):
https://github.com/spring-projects/spring-integration-samples/tree/master/intermediate/rest-http
Service Activator class:
@Service("httpOrderGateway")
public class HttpOrderGateway implements OrderGateway {
private static final Logger LOGGER = Logger.getLogger(HttpOrderGateway.class);
@Override
public Message<CreateOrderResponse> createOrder(Message<CreateOrderRequest> orderRequest) {
LOGGER.info("Received CreateOrderRequest headers: " + orderRequest.getHeaders());
LOGGER.info("Received: " + orderRequest.getPayload());
return MessageBuilder.withPayload(new CreateOrderResponse("Thank you for your order")).build();
}
}
Spring integration XML:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

method="createOrder"
requires-reply="true"
send-timeout="60000" />
<bean id="jaxbJacksonObjectMapper" class="com.anon.order.gateway.json.JaxbJacksonObjectMapper" />
</beans>
Currently, the code logs out:
Received: <CustomerServiceRequest><CustomerName>Robert Pulson</CustomerName></CustomerServiceRequest>
(or the equivalent JSON format), and returns a response in either JSON or XML, depending on the Accept Header, so that part is working.
I have read the following similar question that is based on a previous version of Spring Integration:
Spring Integration : http:inbound-channel adapter - not getting json object in payload
But this uses an inbound-channel-adaptor, not an inbound-gateway as I have.
How do I configure my inbound-gateway to use the marshaller and jaxbJacksonObjectMapper (from the same configuration file) to convert the raw request body into a CreateOrderRequest instance for both JSON/XML please?
