当出现问题而不是重新排队时,如何设置侦听器容器何时 channelTransacted(true) 将消息放入死信队列?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。

我想让事务与外部事务数据库(PlatformTransactionManager)同步。当我在侦听器容器上设置 transactionManager(transactionManager) 时,它总是会重新排队。

你用的是什么版本?我刚刚channelTransacted=true使用 Spring Integration 5.0.2 和 Spring AMQP 2.0.2 以及 Spring Integration 4.3.14 和 Spring AMQP 1.7.6 进行了测试,一切都按预期工作,失败的消息发送到 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:

(正文:'[B@17793549(byte[8])' MessageProperties [headers={x-first-death-exchange=, x-death=[{reason=rejected, count=1, exchange=, time=2 月星期三21 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事务管理器都会发生相同的问题。

请参阅关于回滚已接收消息的说明下的第二个说明。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的行为。1.7.x文档说明您必须将 设置alwaysRequeueWithTxManagerRollbackfalse获取新的(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。
