当消息侦听器容器上的 channelTransacted = true 时，确认模式.AUTO 和确认模式.手动有什么区别？
我知道当我想使用带有 channelTransacted=false 的 acknowledgeMode.MANUAL 时，侦听器必须通过调用 Channel.basicAck() 来确认消息。当侦听器容器具有 channelTransacted = true 时，是否不需要使用 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
