Question

我正在尝试运行一个Spring Boot应用程序（1.4.7.RELEASE），它会将消息吐出到RabbitMQ队列。我的构建成功运行但当我尝试通过mvn clean spring-boot:run运行应用程序时，我在文件ProduceMessage.java中收到以下错误

@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：

启动ApplicationContext时出错。要显示自动配置报告，请在启用“debug”的情况下重新运行应用程序。

***************************申请未能开始**************** ***********        描述：        com.ge.power.tcs.producer.ProduceMessage中的字段ctdMessageConverter需要一个类型的bean   'org.springframework.amqp.support.converter.MessageConverter'那个   无法找到。

动作：

考虑定义类型的bean   你的'org.springframework.amqp.support.converter.MessageConverter'   配置。

的RabbitMQ-producer.xml

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

一旦我们在spring boot中的主Application类中提到$currentTime而不是包含bean实例化的19700101000000，问题就解决了
