Question

您好我使用Spring boot 1.3.5和初学者RabbitMQ。在这个项目中，我有一个RabbitMQ消费者，它消耗来自特定队列的消息。但是在运行应用程序时它继续打印在控制台中的消息下方。而在谷歌浏览我读取设置heartBeat将解决问题，但没有运气对我来说，

14:08:14.892 [SimpleAsyncTaskExecutor-1] DEBUG o.s.a.r.l.BlockingQueueConsumer - Retrieving delivery for Consumer: tags=[{amq.ctag-rDkzcToXLMWqF4fFUIHS0A=notificationQueue}], channel=Cached Rabbit Channel: AMQChannel(amqp://guest@127.0.0.1:5672/,3), conn: Proxy@47914ea3 Shared Rabbit Connection: SimpleConnection@1096fe75 [delegate=amqp://guest@127.0.0.1:5672/], acknowledgeMode=AUTO local queue size=0

它永远结束。亲自找到以下消费者代码：

RabbitMqConfiguration.java

import org.springframework.amqp.rabbit.annotation.EnableRabbit;
import org.springframework.amqp.rabbit.config.SimpleRabbitListenerContainerFactory;
import org.springframework.amqp.rabbit.connection.CachingConnectionFactory;
import org.springframework.amqp.support.converter.Jackson2JsonMessageConverter;
import org.springframework.amqp.support.converter.MessageConverter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableRabbit
public class RabbitMqConfiguration{

@Autowired
private CachingConnectionFactory cachingConnectionFactory;

@Value("${concurrent.consumers}")
public int concurrent_consumers;

@Value("${max.concurrent.consumers}")
public int max_concurrent_consumers;

@Bean
public SimpleRabbitListenerContainerFactory rabbitListenerContainerFactory() {
        SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
        factory.setConnectionFactory(cachingConnectionFactory);
        factory.setConcurrentConsumers(concurrent_consumers);
        factory.setMaxConcurrentConsumers(max_concurrent_consumers);
        factory.setMessageConverter(jsonMessageConverter());
        return factory;
    }

@Bean
public MessageConverter jsonMessageConverter()
{
    final Jackson2JsonMessageConverter converter = new Jackson2JsonMessageConverter();
    return converter;
}

}

NotificationConsumer.java

@Component
public class NotificationConsumer {

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

@Value("${notification.queue}")
public String notificationQueue;

@RabbitListener(id="notification",containerFactory="rabbitListenerContainerFactory",queues = "#{notificationQueue}")
public void handleNotificationMessage(Transaction transaction)
{
    System.out.println("Entered handleNotificationMessage::"+transaction.getId());
    System.out.println("Exit handleNotificationMessage::"+transaction.getData());

    logger.info("Entered handleNotificationMessage::", transaction.getId());
    logger.info("Exit handleNotificationMessage::", transaction.getData());
}

@Bean
public Queue notificationQueue() {
    return new Queue(notificationQueue, true, false, false);
}

}

application.yml

spring:
    rabbitmq:
        addresses: 127.0.0.1:5672
        adminAddresses: http://127.0.0.1:15672
        username: guest
        password: guest
        requested-heartbeat: 60

spring.rabbit.exchange: notification-exchange
notification.queue: notificationQueue
concurrent.consumers: 3
max.concurrent.consumers: 10

消息将由另一个应用程序生成，此应用程序将仅使用该消息。

应该感谢你的帮助。

根据Gary的说法，将记录器级别从DEBUG转移到INFO解决了我的问题。

logging:
    level:
        ROOT: INFO

现在我得到以下异常：

15：21：24.925 [SimpleAsyncTaskExecutor-2] WARN o.s.a.r.l.ConditionalRejectingErrorHandler - 致命消息转换错误;消息被拒绝; 它将被删除或路由到死信交换，如果这样配置:(正文：'{“id”：“5784eed4f5a64b4d8663e706”，“clientIdentifier”：“313131313131”， “data”：“按vad采样数据”，“currentAction”：{“state”：{“status”：“PENDING”，“errorCode”：“404”}，“data”：“示例数据”}， “hasError”：false，“errorMessage”：“”}'MessageProperties [headers = {__ TypeId __ = com.global.produce.model.Transaction}， timestamp = null，messageId = null，userId = null，appId = null，clusterId = null，type = null，correlationId = null，replyTo = null，contentType = application / json， contentEncoding = UTF-8，contentLength = 0，deliveryMode = PERSISTENT，expiration = null，priority = 0，redelivered = false，receivedExchange =， receivedRoutingKey = notificationQueue，deliveryTag = 1，messageCount = 0]）

有人对此错误有任何疑问吗？

那只是DEBUG日志;将日志设置更改为INFO或WARN或ERROR。
