spring amqp 死信队列不适用于事务

Question

当 channelTransacted(true) 发生错误而不是重新排队时，我如何设置监听器容器将消息扔进死信队列？当我不使用 channelTransacted 时，一切正常，我可以在死信队列中看到消息。

@Bean(name = "amqpInboundEsignRequest")
public IntegrationFlow amqpInbound(ConnectionFactory connectionFactory, PlatformTransactionManager transactionManager) {
    return IntegrationFlows.from(
            Amqp.inboundAdapter(connectionFactory, esignIAutoRequestQueue())
                    .acknowledgeMode(AcknowledgeMode.AUTO)
                    .messageConverter(new Jackson2JsonMessageConverter())
                    .autoStartup(false)
                    .defaultRequeueRejected(false)
                    //.channelTransacted(true) // dead letter does not work
                    //.transactionManager(transactionManager) // dead letter does not work
    )
            .log("amqpInbound.start-process")
            .handle(p -> {
                throw new RuntimeException("Something wrong!");
            })
            .get();
}

这些是依赖项的版本。

我想让交易与外部交易数据库 (PlatformTransactionManager) 同步。当我在侦听器容器上设置 transactionManager(transactionManager) 时，它总是重新排队。

您使用的是什么版本？我刚刚用 Spring Integration 5.0.2 和 Spring AMQP 2.0.2，以及 Spring Integration 4.3.14 和 Spring AMQP 1.7 测试了 channelTransacted=true。 6 一切都按预期工作，失败的消息转到 DLQ。

@SpringBootApplication
public class So48914749Application {

    public static void main(String[] args) {
        SpringApplication.run(So48914749Application.class, args);
    }

    @Bean
    public IntegrationFlow amqpInbound(ConnectionFactory connectionFactory) {
        return IntegrationFlows.from(
                Amqp.inboundAdapter(connectionFactory, "foo")
                        .acknowledgeMode(AcknowledgeMode.AUTO)
                        .messageConverter(new Jackson2JsonMessageConverter())
                        .autoStartup(true)
                        .defaultRequeueRejected(false)
                        .channelTransacted(true) // dead letter does not work
        // .transactionManager(transactionManager) // dead letter does not work
        )
                .log("amqpInbound.start-process")
                .handle(p -> {
                    throw new RuntimeException("Something wrong!");
                })
                .get();
    }

    @Bean
    public Queue queue() {
        return QueueBuilder.durable("foo")
                .withArgument("x-dead-letter-exchange", "")
                .withArgument("x-dead-letter-routing-key", "dlq")
                .build();
    }

    @Bean
    public Queue dlq() {
        return new Queue("dlq");
    }

    @RabbitListener(queues = "dlq")
    public void dlq(Message in) {
        System.out.println(in);
    }

}

结果：

(Body:'[B@17793549(byte[8])' MessageProperties [headers={x-first-death-exchange=, x-death=[{reason=rejected, count=1, exchange=, time=Wed Feb 21 16:43:48 EST 2018, routing-keys=[foo], queue=foo}], x-first-death-reason=rejected, x-first-death-queue=foo}, timestamp=null, messageId=null, userId=null, receivedUserId=null, appId=null, clusterId=null, type=null, correlationId=null, correlationIdString=null, replyTo=null, contentType=null, contentEncoding=null, contentLength=0, deliveryMode=null, receivedDeliveryMode=NON_PERSISTENT, expiration=null, priority=null, redelivered=false, receivedExchange=, receivedRoutingKey=dlq, receivedDelay=null, deliveryTag=4, messageCount=0, consumerTag=amq.ctag-dOypXDkkQ5Hvw2W9cUIpzg, consumerQueue=dlq])

以后请更准确；您的问题暗示无论是否提供交易管理器，都会发生同样的问题。

参见 the second NOTE under A note on Rollback of Received Messages。这在 2.0 中已修复。

在 1.7.x 中，为了向后兼容，我们必须默认保留旧行为。 1.7.x documentation 说明您必须将 alwaysRequeueWithTxManagerRollback 设置为 false 以获得新的（一致的）行为。

这是一个侦听器容器属性，因此您需要连接一个容器并将其注入入站通道适配器。
