微服务框架SpringcloudAlibaba+Nacos集成RabbitMQ

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

在这里插入图片描述

rabbitmq模块:

2.核心配置

1.pom类

2.ConditionalOnRabbit

package com.jeeplus.common.rabbit.conditional;

import org.springframework.context.annotation.Conditional;

import java.lang.annotation.*;

/**
 * 判断系统是否在启用了Rabbit, 未启用的情况下不将Bean注册到系统中
 *
 * 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。

 * @author xxm
 * @since 2022/12/12
 */
@Target({ ElementType.TYPE })
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Conditional(OnRabbitEnable.class)
public @interface ConditionalOnRabbit {

}

3.OnRabbitEnable

package com.jeeplus.common.rabbit.conditional;

import org.springframework.boot.context.properties.bind.Binder;
import org.springframework.context.annotation.Condition;
import org.springframework.context.annotation.ConditionContext;

 */
public class OnRabbitEnable implements Condition {

    private final String rabbitPropertiesPrefix = "com.jeeplus.common.rabbit";

    /**
     * @param context
     * @param metadata
     * @return
     */
    @Override
    public boolean matches(ConditionContext context, AnnotatedTypeMetadata metadata) {
        RabbitMqProperties rabbitMqProperties = Binder.get(context.getEnvironment())
            .bind(rabbitPropertiesPrefix, RabbitMqProperties.class)
            .orElse(new RabbitMqProperties());
        return rabbitMqProperties.isEnable();

        MappingJackson2MessageConverter converter = new MappingJackson2MessageConverter();
        converter.setObjectMapper(objectMapper);
        factory.setMessageConverter(converter);
        return factory;
    }

}

6.RabbitMqConfigurer

package com.jeeplus.common.rabbit.configuration;

import com.fasterxml.jackson.databind.ObjectMapper;

public class RabbitMqProperties {

    /**
     * 是否开启 RabbitMQ功能,
     * @see ConditionalOnRabbit 配合此注解使用
     */
    private boolean enable = false;

}

8.RabbitMqCommonAutoConfiguration

package com.jeeplus.common.rabbit;

/**
 * RabbitMQ配置
 *
 * @author xxm
 * @since 2022/5/3
 */
@SpringBootApplication
public class RabbitMqCommonAutoConfiguration {

}

在这里插入图片描述

9.org.springframework.boot.autoconfigure.AutoConfiguration.imports

RabbitMqCommonAutoConfiguration

10.spring.factories

## 配置自定义 starter 的自动化配置
org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
  com.jeeplus.common.rabbit.RabbitMqCommonAutoConfiguration

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
在这里插入图片描述

  #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

在这里插入图片描述

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+"]");
        });
    }
}

@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。

    /**
     * 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;
    }

希望对你有用!
