springBoot整合RabbitMq实现手动确认消息

如何保证消息的可靠性投递？

1.保证生产者向broke可靠性投递，开启ack投递成功确认，如果失败的话进行消息补偿

/**
 * @author yueF_L
 * @date 2023-08-10 01:32
 * ConfirmCallback：消息只要被 RabbitMQ broker 接收到就会触发confirm方法。
 */
@Slf4j
@Component
public class ConfirmCallbackService implements RabbitTemplate.ConfirmCallback {

  
    @Override
    public void confirm(CorrelationData correlationData, boolean ack, String cause) {
        if (!ack) {
            log.error("confirm==>发送到broker失败\r\n" +
                            "correlationData={}\r\n" + "ack={}\r\n" + "cause={}",
                    correlationData, ack, cause);
        } else {
            log.info("confirm==>发送到broker成功\r\n" +
                            "correlationData={}\r\n" + "ack={}\r\n" + "cause={}",
                    correlationData, ack, cause);
        }
    }

2. 保证消息能投敌到目标 queue

/**
 * @author yueF_L
 * @date 2023-08-10 01:29
 * ReturnCallback：如果消息未能投递到目标 queue 里将触发returnedMessage方法。
 * 若向 queue 投递消息未成功，可记录下当前消息的详细投递数据，方便后续做重发或者补偿等操作。
 */
@Slf4j
@Component
public class ReturnCallbackService implements RabbitTemplate.ReturnCallback {


    @Override
    public void returnedMessage(Message message, int replyCode, String replyText,
                                String exchange, String routingKey) {
        log.info("returnedMessage==> \r\n" + "message={}\r\n" + "replyCode={}\r\n" +
                        "replyText={}\r\n" + "exchange={}\r\n" + "routingKey={}",
                message, replyCode, replyText, exchange, routingKey);
    }
}

将配置set到rabbitTemplate

/**
 * @author yueF_L
 * @date 2023-08-10 01:25
 * 消息队列配置
 */
@Slf4j
@Configuration
@RequiredArgsConstructor
public class RabbitMQConfig {

    private final ConfirmCallbackService confirmCallbackService;

    private final ReturnCallbackService returnCallbackService;

    @Bean
    RabbitTemplate rabbitTemplate(ConnectionFactory connectionFactory) {
        RabbitTemplate rabbitTemplate = new RabbitTemplate(connectionFactory);
        // 开启失败通知
        rabbitTemplate.setMandatory(true);
        rabbitTemplate.setConfirmCallback(confirmCallbackService);
        rabbitTemplate.setReturnCallback(returnCallbackService);
        return rabbitTemplate;
    }
}

yml配置

 代码中的调用

 

  @RabbitListener(queues = TtlQueueConfig.DEAD_LETTER_QUEUE_TELEPHONE_BILL)
    public void receiveD(Message message, Channel channel) {
        try {
            try {
                String msg = new String(message.getBody());
                // 模拟异常，测试重试
                int a = 1 / 0;
                //apiService.doApiHeartChainTelephoneBillOrder(msg);
                // 手动确认消息
                channel.basicAck(message.getMessageProperties().getDeliveryTag(), false);
                log.info("当前时间：{},收到话费死信队列信息：{}", new Date(), msg);
            }catch (Exception e){
                //参数1：消费消息的index
                //参数2：是否批量否定多个消息，设为false就与basicReject功能一样，triue的前提也是在同一个channel，且在该消息否定前存在未确认的消息
                //参数3： 对异常消息的处理，true表示重排序，false表示丢弃
                // 如果拒绝消息，要求mq重发的话，一直异常会进入死循环
                //channel.basicNack(message.getMessageProperties().getDeliveryTag(), false, true);
                log.error(TtlQueueConfig.DEAD_LETTER_QUEUE_TELEPHONE_BILL + " 消息反馈失败，param:{}", message.getBody());
                throw e;
            }
        } catch (Exception e) {
            log.error("监听RabbitMq、队列：" + TtlQueueConfig.DEAD_LETTER_QUEUE_TELEPHONE_BILL + "发生异常："+ e.getMessage());
            throw new CustomException("监听RabbitMq、队列：" + TtlQueueConfig.DEAD_LETTER_QUEUE_TELEPHONE_BILL + "发生异常："+ e.getMessage());
        }
    }
