springBoot integra RabbitMq para implementar mensajes de confirmación manual

¿Cómo garantizar la entrega confiable de mensajes?

1. Garantizar la entrega confiable del productor al corredor, habilitar la entrega de acuse de recibo para confirmar el éxito y realizar una compensación del mensaje si falla.

 * 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. Asegúrese de que el mensaje pueda entregarse a la cola de destino.

/**

 * @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。

@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);
    }
}
