Question

在消息侦听器容器上channelTransacted = true时，acknowledgeMode.AUTO和acknowledgeMode.MANUAL有什么区别？

据我所知，当我想在channelTransacted = false时使用acknowledgeMode.MANUAL时，监听器必须通过调用Channel.basicAck（）来确认消息。当侦听器容器有channelTransacted = true时，是否不必使用acknowledgeMode.MANUAL？因为当我将acknowledgeMode.MANUAL和channelTransacted = true与调用Channel.basicAck（）结合起来时，我得到了异常。

@Bean(name = "amqpInboundEsignRequest")
public IntegrationFlow amqpInbound(ConnectionFactory connectionFactory, PlatformTransactionManager transactionManager) {
    return IntegrationFlows.from(
            Amqp.inboundAdapter(connectionFactory, EsignContstants.QUEUE)
                    .acknowledgeMode(AcknowledgeMode.MANUAL)
                    .messageConverter(new Jackson2JsonMessageConverter())
                    .autoStartup(false)
                    .channelTransacted(true)
                    .transactionManager(transactionManager)
                    .txSize(1)
    )
            .enrichHeaders(s -> s.header(MessageHeaders.REPLY_CHANNEL, "basicAck.flow", true))
            .log("amqpInbound.start-process")
            .channel("insertAndStartProcess.input")
            .get();
}

例外

Answer 1

使用交易不应该有任何区别;该错误意味着在您收到邮件并发送basicAck之间由于某种原因关闭了频道，我们在事务提交之前不会检测到这些事务。

我们最近added a fix to detect the channel was closed并在这种情况下拒绝basicAck。

修复程序位于2.0.2.RELEASE。
