目前公司使用jeepluscloud版本,这个版本没有集成消息队列,这里记录一下,集成的过程;这个框架跟ruoyi的那个微服务版本结构一模一样,所以也可以快速上手。
1.项目结构图:
配置类的东西做成一个公共的模块
rabbitmq模块:
2.核心配置
1.pom类

2.ConditionalOnRabbit

/**

* 使用场景: 在不使用Rabbit中间件但未去除Rabbit依赖的情况下, 通过配置文件中关闭Rabbit选项,
* 同时将这个注解到有`@RabbitListener`标志的类上,让这个对象不注册到Spring容器中,
* 从而避免`RabbitMQ`进行无限尝试重连服务器,导致项目一直抛出异常,影响开发和使用。

RabbitMqCommonAutoConfiguration
10.spring.factories
## 配置自定义 starter 的自动化配置
org.springframework.boot.autoconfigure.EnableAutoConfiguration=\

3. nacos配置
哪一个服务模块需要消息队列,就在对应的yml文件中配置 rabbit链接
#rabbitmq
rabbitmq:
host: localhost
port: 5627
username: root
password: root123
virtual-host: /
publisher-confirm-type: correlated
listener:
simple:
acknowledge-mode: manual
4.服务中调用rabbitmq
建立两个包,配置类和监听类
1.mq模板配置
package com.jeeplus.duxin.config;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.amqp.support.converter.Jackson2JsonMessageConverter;
import org.springframework.amqp.support.converter.MessageConverter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
/**
* mq模板
* @author lgn
* @date 2023/10/28 10:15
*/
@Configuration
public class MyRabbitConfig {
private RabbitTemplate rabbitTemplate;
@Primary
@Bean
public RabbitTemplate rabbitTemplate(ConnectionFactory connectionFactory) {
RabbitTemplate rabbitTemplate = new RabbitTemplate(connectionFactory);
this.rabbitTemplate = rabbitTemplate;
rabbitTemplate.setMessageConverter(messageConverter());
initRabbitTemplate();
return rabbitTemplate;
}
@Bean
public MessageConverter messageConverter() {
return new Jackson2JsonMessageConverter();
}
/**
* 定制RabbitTemplate
* 1、服务收到消息就会回调
* 1、spring.rabbitmq.publisher-confirms: true
* 2、设置确认回调
* 2、消息正确抵达队列就会进行回调
* 1、spring.rabbitmq.publisher-returns: true
* spring.rabbitmq.template.mandatory: true
* 2、设置确认回调ReturnCallback
*
* 3、消费端确认(保证每个消息都被正确消费,此时才可以broker删除这个消息)
*
*/
// @PostConstruct //MyRabbitConfig对象创建完成以后,执行这个方法
public void initRabbitTemplate() {
/**
* 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
*/
//设置确认回调
rabbitTemplate.setConfirmCallback((correlationData,ack,cause) -> {
System.out.println("confirm...correlationData["+correlationData+"]==>ack:["+ack+"]==>cause:["+cause+"]");
});
/**
* 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
*/
rabbitTemplate.setReturnCallback((message,replyCode,replyText,exchange,routingKey) -> {
System.out.println("Fail Message["+message+"]==>replyCode["+replyCode+"]" +
"==>replyText["+replyText+"]==>exchange["+exchange+"]==>routingKey["+routingKey+"]");
});
}
}
2.服务交换机 队列设置

}
3.监听队列 接收消息
消费方消费消息
package com.jeeplus.duxin.listener;
import com.rabbitmq.client.Channel;
import lombok.extern.slf4j.Slf4j;
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 java.io.IOException;
/**
* 监听路由信息
* @author lgn
* @date 2023/10/28 10:33
*/
@Slf4j
@Component
//@RabbitListener标注在方法上,直接监听指定的队列,此时接收的参数需要与发送时类型一致
//@RabbitListener 注解是指定某方法作为消息消费的方法,例如监听某 Queue 里面的消息。
@RabbitListener(queues = "bom.maintenance.queue")
public class MQTestListener {
//@RabbitListener 可以标注在类上面,需配合 @RabbitHandler 注解一起使用
//@RabbitListener 标注在类上面表示当有收到消息的时候,就交给 @RabbitHandler 的方法处理,根据接受的参数类型进入具体的方法中。
@RabbitHandler
public void listener(String info,Channel channel, Message message) throws IOException {
System.out.println("=============接收消息开始执行:"+info);
try {
channel.basicAck(message.getMessageProperties().getDeliveryTag(),false);
} catch (Exception e) {
channel.basicReject(message.getMessageProperties().getDeliveryTag(),true);
}
}
}
5.使用
使用起来也非常方便:
在业务service中直接调用,生产者消息发送。文章来源:https://www.toymoban.com/news/detail-731750.html
/**
* mqTest
* @author lgn
* @date 2023/10/28 10:03
* @return Object
*/
public String mqTest() {
//TODO 订单创建成功,发送消息给MQ
rabbitTemplate.convertAndSend("bom-event-exchange","bom.maintenance.create","1234");
return null;
}
