RabbitMQ学习06--消息可靠性(SpringBoot方式)

1、配置文件增加如下内容：

application.yml修改如下：

spring:
  rabbitmq:
    publisher-confirm-type: simple #开启confirm机制
    publisher-returns: true #开启return机制

2、增加配置类：

package com.yas.rabbitmqboot.config;

import org.springframework.amqp.core.ReturnedMessage;
import org.springframework.amqp.rabbit.connection.CorrelationData;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import javax.annotation.PostConstruct;

@Component
public class PublisherConfirmAndReturnConfig implements RabbitTemplate.ConfirmCallback, RabbitTemplate.ReturnsCallback {

    @Autowired
    RabbitTemplate rabbitTemplate;

    @PostConstruct
    public void initMethod() {
        rabbitTemplate.setConfirmCallback(this);
        rabbitTemplate.setReturnsCallback(this);
    }

    @Override
    public void confirm(CorrelationData correlationData, boolean b, String s) {
        if (b) {
            System.out.println("消息已经送达Exchange，ack已发");
        } else {
            System.out.println("消息没有送达Exchange");
        }
    }

    @Override
    public void returnedMessage(ReturnedMessage returnedMessage) {
        System.out.println("消息没有送到队列中");
    }
}
