1、编写配置
# rabbitmq的抵达队列的发送端确认(ReturnCallback)
spring.rabbitmq.publisher-returns=true
# 只要抵达队列,以异步方式优先回调我们这个returnconfirm
spring.rabbitmq.template.mandatory=true
2、在自己的rabbit的配置类中重写rabbitTemplate
package com.gulimall.order.config;
import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.connection.CorrelationData;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.amqp.support.converter.Jackson2JsonMessageConverter;
import org.springframework.amqp.support.converter.MessageConverter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.annotation.PostConstruct;
@Configuration
public class MyRabbitConfig {
private RabbitTemplate rabbitTemplate;
@Bean
public MessageConverter messageConverter(){
return new Jackson2JsonMessageConverter();
}
/**
* 定制RabbitTemplate
*/
@PostConstruct //在MyRabbitConfig对象创建完成后执行这个方法
public void initRabbitTemplate(){
//设置确认回调
rabbitTemplate.setConfirmCallback(new RabbitTemplate.ConfirmCallback() {
/**
* 1、只要消息抵达Broker就ack=true
* correlationData:当前消息的唯一关联数据(这个是消息的唯一id)
* ack:消息是否成功收到
* cause:失败的原因
*/
@Override
public void confirm(CorrelationData correlationData, boolean ack, String cause) {
System.out.println("confirm...correlationData["+correlationData+"]==>ack:["+ack+"]==>cause:["+cause+"]");
}
});
//设置消息发送到队列的回调(只有发送失败才会回调)
rabbitTemplate.setReturnCallback(new RabbitTemplate.ReturnCallback() {
/**
* 只要消息【没有】投递给指定的队列,就触发这个失败回调
* message:投递失败的消息详细信息
* replyCode:回复的状态码
* replyText:回复的文本内容
* exchange:当时这个消息发给哪个交换机
* routingKey:当时这个消息用哪个路邮键
*/
@Override
public void returnedMessage(Message message, int replyCode, String replyText, String exchange, String routingKey) {
System.out.println("Fail Message["+message+"]==>replyCode["+replyCode+"]" +
"==>replyText["+replyText+"]==>exchange["+exchange+"]==>routingKey["+routingKey+"]");
}
});
}
}
