Question

当我的交易标记为回滚时，我不希望SimpleMessageListenerContainer继续使用这些消息。

我没有在配置文件中添加listener-container并尝试重新抛出AmqpRejectAndDontRequeueException。它不起作用。这是我的代码库：

@Transactional
 public class MySecondService {

    @Resource
    private MySecondRepository mySecondRepository;

    @Transactional(propagation = Propagation.REQUIRED)
    @ServiceActivator(inputChannel = "my-first-servie-output-channel",
                      outputChannel = "my-Second-servie-output-channel")
    public String saveEntity(final MyTestEntity myTestEntity) 
        throws AmqpRejectAndDontRequeueException {
         try {
            mySecondRepository.save(myTestEntity);
         } catch (Exception e) {
            throw new AmqpRejectAndDontRequeueException("exception");
        }
    }
}

弹簧整合-context.xml中

<int:chain input-channel="transaction-inbound-channel" output-channel="my-first-servie-input-channel">
    </int:chain>
<int-amqp:inbound-channel-adapter
            channel="transaction-inbound-channel"
            queue-names="sample.queue"
            concurrent-consumers="5"
            error-channel="failed-channel"
            connection-factory="rabbitConnectionFactory"
            mapped-request-headers="*" 
            transaction-manager="transactionManager" />

    <rabbit:connection-factory
            id="rabbitConnectionFactory"
            connection-factory="rcf"
            host="${spring.rabbitmq.host}"
            port="${spring.rabbitmq.port}"
            username="${spring.rabbitmq.username}"
            password="${spring.rabbitmq.password}"
            />
    <bean id="rcf" class="com.rabbitmq.client.ConnectionFactory">
        <property name="host" value="${spring.rabbitmq.host}"/>
        <property name="requestedHeartbeat" value="10" />
    </bean>

这是堆栈跟踪：

我不希望这种情况发生org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer - Restarting Consumer

有人可以帮助我添加我需要添加的其他内容来重新抛出AmqpRejectAndDontRequeueException。提前谢谢。

你没有显示流程。

如果您只是调用单个服务，则不要将事务管理器添加到入站通道适配器。

事务将在调用服务时启动;只要failed-channel上的错误流不会引发异常（或抛出AmqpRejectAndDontRequeueException），该消息就不会被重新排队。

如果您有多个服务要参与单个事务，则可以使用AOP建议进行事务transaction-inbound-channel，下游流程将全部在该事务中运行。

或者，如果您从不希望邮件重新排队，请在入站适配器的容器中设置defaultRequeueRejected为false（您必须连接到该容器）作为<bean/>）。

在TransactionSystemException之后，SimpleMessageListenerContainer持续消耗
