Spring-boot 2 rabbitmq MessageConverter not working as excepted - spring-rabbit

Question

I am using the springboot and rabitmq. I have kind of similar scenario here.
I would like to map my message to custom java object
I also want pass delivery tag which is message proprieties
I wann to pass Channel as well beacuse I need to manual ack messages
My code is like this
#RunWith(SpringRunner.class)
public class EPPQ2SubscriberTest {
#Autowired
private RabbitListenerEndpointRegistry registry;
public final String sampleMessage = "{" + "\"header\": {" + "\"RETRY_COUNT\":0," + "\"PUBLISH_EVENT_TYPE\":\"AUTH\""
+ "}," + "\"payLoad\":{" + "\"MTI\": \"120\"," + "\"MTI_REQUEST\": \"120\","
+ "\"PAN\": \"6011000000000000\"" + "}" + "}";
#Test
public void message_converter_test() throws Exception {
SimpleMessageListenerContainer container = (SimpleMessageListenerContainer) this.registry
.getListenerContainer("messageListener");
ChannelAwareMessageListener listener = (ChannelAwareMessageListener) container.getMessageListener();
Message message = MessageBuilder.withBody(sampleMessage.getBytes())
.andProperties(MessagePropertiesBuilder.newInstance().setContentType("application/json").build())
.build();
listener.onMessage(message, mock(Channel.class));
}
#Configuration
#EnableRabbit
public static class config {
#Bean
public ConnectionFactory mockConnectionFactory() {
return mock(ConnectionFactory.class);
}
#Bean
public MessageConverter messageConverter() {
Jackson2JsonMessageConverter messageConverter = new Jackson2JsonMessageConverter();
/*
* DefaultClassMapper classMapper = new DefaultClassMapper();
* classMapper.setDefaultType(com.discover.dftp.scrubber.domain.Message.class);
* messageConverter.setClassMapper(classMapper);
*/
return messageConverter;
}
#Bean
public SimpleRabbitListenerContainerFactory rabbitListenerContainerFactory() {
SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
factory.setConnectionFactory(mockConnectionFactory());
factory.setMessageConverter(messageConverter());
factory.setAutoStartup(false);
return factory;
}
#Bean
public EPPQ2Subscriber messageListener() {
return new EPPQ2Subscriber();
}
}
}
#Component
public class EPPQ2Subscriber {
private static final Logger LOGGER = LoggerFactory.getLogger(EPPQ2Subscriber.class);
// #RabbitListener(queues = "#{queue.getName()}") #TODO I wann to use this in
// later point in time.. !
#RabbitListener(id = "messageListener", queues = "TestQueue")
public void receiveMessage(Message message, Channel channel/* ,#Header(AmqpHeaders.DELIVERY_TAG) long tag */) {
LOGGER.info("Method receiveMessage invoked");
message.getMessageProperties().getDeliveryTag();
LOGGER.info("Result:" + message.getClass() + ":" + message.toString());
}
}
public class Message implements Serializable {
private static final long serialVersionUID = 1L;
private Map<String, Object> header;
private Map<String, Object> payLoad;
public Map<String, Object> getHeader() {
return header;
}
public void setHeader(Map<String, Object> header) {
this.header = header;
}
public Map<String, Object> getPayLoad() {
return payLoad;
}
public void setPayLoad(Map<String, Object> payLoad) {
this.payLoad = payLoad;
}
#Override
public String toString() {
return "Header [header=" + this.header + ", payLoad=" + this.payLoad + "]";
}
}

Answer 1

#RabbitListener(id = "messageListener", queues = "TestQueue")
public void receiveMessage(Message message, Channel channel/* ,#Header(AmqpHeaders.DELIVERY_TAG) long tag */) {
LOGGER.info("Method receiveMessage invoked");
message.getMessageProperties().getDeliveryTag();
LOGGER.info("Result:" + message.getClass() + ":" + message.toString());
}
I looks like that method receives the raw (unconverted) Spring AMQP Message (you are importing the wrong Message class in EPPQ2Subscriber).
