Java RabbitMQ MessageConverter在运行Spring启动应用程序时出现错误

我正在尝试运行spring启动应用程序1.4.7.RELEASE，它将向RabbitMQ队列吐出消息。我的构建工作成功，但当我试图通过mvn clean spring boot:run运行应用程序时，我在文件ProduceMessage.java中遇到以下错误

@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;
    }
}

错误：

***************************应用程序无法启动*************************** 说明： com.ge.power.tcs.producer.ProduceMessage中的字段ctdMessageConverter需要类型为的bean 'org.springframework.amqp.support.converter.MessageConverter'表示 找不到

行动：

考虑定义类型为的bean 您的应用程序中的“org.springframework.amqp.support.converter.MessageConverter” 配置

rabbitmq-producer.xml

<beans xmlns="http://www.springframework.org/schema/beans"

当我们在spring boot的主应用程序类中提到@ImportResourceclasspath:META-INF/spring/rabbitmq-producer.xml，而不是包含bean实例化的@ContextConfigurationclasspath:META-INF/spring/rabbitmq-producer.xml时，问题就解决了，您是否有要注入的消息转换器的@bean定义这里？它是import org.springframework.amqp.support.converter.MessageConverter；实例我的问题是，您到底希望在这里注入什么，为什么是您的期望？这在您共享的代码中并不明显。@sromit autoconfiguration不提供MessageConverter类型的bean，如果您是自动连接，那么您必须使用c创建edwin提到的MessageConverter类型的bean。如何创建MessageConverter类型的bean？
