java - RabbitMQ MessageConverter在运行Spring Boot应用程序时出现错误

我正在尝试运行一个Spring Boot应用程序（1.4.7.RELEASE），它将把消息吐出到RabbitMQ队列中。我的构建成功运行，但是当我尝试通过mvn clean spring-boot:run运行应用程序时，文件ProduceMessage.java中出现以下错误

@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;
    }
}

       描述：
       com.ge.power.tcs.producer.ProduceMessage中的字段ctdMessageConverter需要一个类型为bean的bean
  'org.springframework.amqp.support.converter.MessageConverter'
  找不到。
  
  行动：
  
  考虑定义一个类型的bean
  您的'org.springframework.amqp.support.converter.MessageConverter'
  组态。

最佳答案

一旦我们在Spring Boot的主Application类中提到了@ImportResource("classpath:META-INF/spring/rabbitmq-producer.xml")而不是包含豆实例化的@ContextConfiguration("classpath:META-INF/spring/rabbitmq-producer.xml")，就解决了该问题
