我们有一个应用程序，它使用Spring AMPQ和RabbitListener从多个队列中读取RabbitMQ消息。像这样的东西
@RabbitListener(queues = {"#{'${rabbit.queues}'.split(',')}"})
public void processRabbitMessage(@Payload String data, @Header(AmqpHeaders.CONSUMER_QUEUE) String queue, @Header(AmqpHeaders.MESSAGE_ID) String messageId) throws Exception {
// Do some stuff
}
但是我收到了一个间歇性错误，其中未设置邮件头。

所有消息都以完全相同的方式（如下所示）写入队列，并且来自相同的源，因此通常是相同的结构。
MessageProperties msgprop = new MessageProperties()
msgprop.setContentType(MessageProperties.CONTENT_TYPE_TEXT_PLAIN)
msgprop.setAppId(routing)
rabbitTemplate.send(exchange, routing, new Message(message.getBytes(), msgprop))
我们没有丢失数据，因为我们可以捕获DLX中所有被拒绝的消息，但是当我们不知道它们来自哪个队列时很难重新处理。
我们知道没有消息是空的/格式错误的（甚至是那些生成错误的消息），我的印象是这是Rabbit根据写入消息的队列设置的头，所以它怎么可以为null ？
有关某些而非所有消息的此标头如何为null以及/或确保标头设置的可能修复的任何想法？
编辑：添加了最后一次尝试阅读邮件的DEBUG日志。我们制定了无国籍重试政策，因此已经尝试了两次。

答案 0 :(得分：0)
我不明白这是怎么回事;我们unconditionally set the consumerQueue property in the received message - 这是该标头的来源。我们维护了一张consumerTag的地图 - ＆gt;用于此目的的队列名称。
显示此行为的消息传递的DEBUG日志将非常有用。
