Question

下面是我在rabbitmq listener的xml文件中的声明性配置。使用advic链重试似乎没有发生.DLQMessageRecoverer类正在抛出RabbitmqRejectAndDontRequeue异常。它似乎也没有调用它。

  scope :duebylastresult, -> {
    find_by_sql(
      'SELECT *
       FROM checks
       LEFT OUTER JOIN 
            (SELECT id AS tick_id,
                    check_id AS check_id,
                    date AS tick_date, 
                    result AS tick_result,
                    dense_rank() OVER (
                      PARTITION BY ticks.check_id
                      ORDER BY ticks.date DESC
                    ) AS tick_rank
             FROM ticks) AS ranked_ticks ON checks.id = ranked_ticks.check_id
       WHERE tick_rank = 1 AND tick_result >= 3;'
    )
  }

我认为你应该设置spring.rabbitmq.listener.retry.enabled属性true。默认情况下，RabbitMQ不会重试失败的消息（假设失败是在消费者端）。

同样AmqpRejectAndDontRequeueException阻止您的邮件被重新排队。
