rabbitmq重试机制存在的问题

以下内容基于上一篇springboot整合rabbitmq

1、重试

1.1 配置

消费者中添加如下配置

# 开启自动重试
spring.rabbitmq.listener.simple.retry.enabled=true
# 最大重试次数
spring.rabbitmq.listener.simple.retry.max-attempts=5
# 重试时间间隔
spring.rabbitmq.listener.simple.retry.initial-interval=3000

2、消费者改造

SmsConsumer

package com.mine.consumer;

import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

import com.rabbitmq.client.Channel;

import lombok.extern.slf4j.Slf4j;

@Component
@Slf4j
public class SmsConsumer {

	@RabbitListener(queues = "queue_sms")
	@RabbitHandler
	public void process(Message message, Channel channel) throws Exception {
		// 获取消息Id，用消息ID做业务判断
		String messageId = message.getMessageProperties().getMessageId();
		String content = new String(message.getBody(), "UTF-8");
		log.info("接收到短信队列消息：" + content + "，消息ID：" + messageId);

		if ("error".equals(content)) {
			throw new Exception("手动抛出异常");
		}

		// 手动签收
		channel.basicAck(message.getMessageProperties().getDeliveryTag(), false);
	}
}

3、测试

3.1 发送消息

依次发送如下消息，第二条消息会抛出异常，重试5次，每次间隔3秒。

1. i am message!
2. error
3. message
4. message2
5. message3

3.2 日志

日志信息如下

3.3 结论

如果其中某条消息发生错误，重试过程中，会把消息放到队列头部，导致后面的消息无法正常消费。先记录一下，后面再考虑如何解决此问题。
