RabbitMQ MessageConverter giving error when running Spring Boot app

I am trying to run a spring boot app (1.4.7.RELEASE) which will spit out message to a RabbitMQ queue. My build works successfully but when I am trying to run the app by mvn clean spring-boot:run, I am getting the following error in the file ProduceMessage.java

@PropertySource("classpath:application.properties")
@Component
@ContextConfiguration("classpath:META-INF/spring/rabbitmq-producer.xml")
public class ProduceMessage {

    private static final Logger logger = LoggerFactory.getLogger(ProduceMessage.class.getName());

    @Autowired
    private RabbitTemplate myEventTemplate;

    @Autowired
    private MessageConverter ctdMessageConverter;

    @Value("${fieldChangedEvent.MainQueue}")
    private String mainQ;

    /*
     * (non-Javadoc)
     * 
     * @see com.ge.predix.dispatcherqproducer.api.produceFieldChangedEvent#
     * produceFieldChangedEvent(com.ge.dsp.pm.solution.service.fieldchanged.
     * FieldChangedEvent)
     */
    public boolean produceStringMessage(String data) {

        logger.debug("In produceStringMessage......");

        MessageProperties prop = new MessageProperties();
        prop.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN);

        Message msg = ctdMessageConverter.toMessage(data, prop);

        logger.debug("publishing string to ......= " + mainQ);
        myEventTemplate.convertAndSend(mainQ, msg);

        return true;
    }
}

The error :

The issue was resolved once we mention @ImportResource("classpath:META-INF/spring/rabbitmq-producer.xml") in the main Application class in spring boot instead of @ContextConfiguration("classpath:META-INF/spring/rabbitmq-producer.xml") which contains the bean instantiation
