RabbitMQ MessageConverter在運行Spring Boot應用程序時出現錯誤

我試圖運行一個彈出式啓動應用程序（1.4.7.RELEASE），它會將消息吐出到RabbitMQ隊列中。我的建築工作順利，但是當我試圖通過mvn clean spring-boot:run運行應用程序，我收到以下錯誤在文件ProduceMessage.javaRabbitMQ MessageConverter在運行Spring Boot應用程序時出現錯誤

@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; 
    } 
}

錯誤：

啓動ApplicationContext時出錯。要顯示自動配置報告，請啓用'debug'重新運行您的應用程序。

***************************應用程序啓動失敗*************************** 描述： com.ge.power.tcs.producer.ProduceMessage中的字段ctdMessageConverter需要一個類型的bean 'org.springframework.amqp.support.converter.MessageConverter'找不到。

操作：

考慮您的配置中定義型 'org.springframework.amqp.support.converter.MessageConverter' 的豆。

的RabbitMQ-producer.xml

，做你有一個你想注入的消息轉換器的'@ Bean'定義？ –

其導入org.springframework.amqp.support.converter.MessageConverter;實例 – sromit

我的問題是，你期望在這裏注入什麼，爲什麼是你的期望？這在您分享的代碼中並不明顯。 –

一旦我們在主應用程序類在春季啓動，而不是@ContextConfiguration("classpath:META-INF/spring/rabbitmq-producer.xml")提@ImportResource("classpath:META-INF/spring/rabbitmq-producer.xml")的問題就解決了其中包含的bean實例
