一、大佬给的配置

spring:
  #activemq延迟队列
  activemq:
    inMemory: false
    broker-url: tcp://47.108.204.1:61616
    user: admin
    password: admin

二、添加依赖和俩文件

在这里插入图片描述

ActiveMQ依赖

<!--activeMq-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-activemq</artifactId>
</dependency>

第一个配置文件------ActiveMQConfiguration

package com.nxt.order.utils.ActiveMQ;

@Configuration

        RedeliveryPolicy redeliveryPolicy = new RedeliveryPolicy();

        //重发时间间隔,默认为1秒
        redeliveryPolicy.setInitialRedeliveryDelay(1000);
        //第一次失败后重新发送之前等待500毫秒,第二次失败再等待500 * 2毫秒,这里的2就是value
        redeliveryPolicy.setBackOffMultiplier(2);
        //最大传送延迟，只在useExponentialBackOff为true时有效（V5.5），假设首次重连间隔为10ms，倍数为2，那么第
        //二次重连时间间隔为 20ms，第三次重连时间间隔为40ms，当重连时间间隔大的最大重连时间间隔时，以后每次重连时间间隔都为最大重连时间间隔。
        redeliveryPolicy.setMaximumRedeliveryDelay(1000);
        factory.setRedeliveryPolicy(redeliveryPolicy);
        return factory;
    }

    //在Topic模式中，对消息的监听需要对containerFactory进行配置
    @Bean("topicJmsListenerContainerFactory")
    public JmsListenerContainerFactory<?> topicJmsListenerContainerFactory(
            //将“innerConnectionFactory”这个Bean注入
            @Qualifier("innerConnectionFactory") ActiveMQConnectionFactory connectionFactory) {
        SimpleJmsListenerContainerFactory factory = new SimpleJmsListenerContainerFactory();
        factory.setConnectionFactory(connectionFactory);
        factory.setSessionTransacted(true);
        factory.setPubSubDomain(true);
        return factory;
    }

    @Bean("queueJmsListenerContainerFactory")

        return factory;
    }
}

第二个配置文件------ActivemqOperator

package com.nxt.order.utils.ActiveMQ;

import org.apache.activemq.ScheduledMessage;
import org.apache.activemq.command.ActiveMQQueue;
import org.apache.activemq.command.ActiveMQTopic;

import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.stereotype.Component;

import javax.jms.*;

/**
 * @author LunarYouI
 * @create 2021-08-04 11:36
 */
@Component
public class ActivemqOperator {
    private final JmsMessagingTemplate jmsTemplate;
    @Autowired
    public ActivemqOperator(JmsMessagingTemplate jmsTemplate) {
        this.jmsTemplate = jmsTemplate;
    }

    /**
     * 发送主题消息
     */
    public void sendMsgTopic(String topic, String message) {
        Destination destination = new ActiveMQTopic(topic);
        jmsTemplate.convertAndSend(destination, message);
    }

    /**
     * 发送队列消息
     */
    public void sendMsgQueue(String queue, String message) {
        Destination destination = new ActiveMQQueue(queue);
        jmsTemplate.convertAndSend(destination, message);
    }

    /**
     * 发送延时队列消息
     */
    public <T> void delaySend(String queue, String message, Long time) {
        Connection connection = null;
        Session session = null;
        MessageProducer producer = null;
        ConnectionFactory connectionFactory = jmsTemplate.getConnectionFactory();
        Destination destination = new ActiveMQQueue(queue);
        try {
            connection = connectionFactory.createConnection();
            connection.start();
            session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
            producer = session.createProducer(destination);
            producer.setDeliveryMode(JmsProperties.DeliveryMode.PERSISTENT.getValue());
            ObjectMessage objectMessage = session.createObjectMessage(message);

            objectMessage.setLongProperty(ScheduledMessage.AMQ_SCHEDULED_DELAY, time);

            producer.send(objectMessage);
            session.commit();
        } catch (Exception e) {
            throw new RuntimeException("delaySend exception : " + e.getMessage());
        } finally {
            try {
                if (producer != null) {
                    producer.close();
                }
                if (session != null) {
                    session.close();
                }
                if (connection != null) {
                    connection.close();
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }
}

三、演示效果

package com.nxt.order.controller;

import com.nxt.order.utils.ActiveMQ.ActivemqOperator;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.text.SimpleDateFormat;
import java.util.Date;

/**
 * @author LunarYouI
 * @create 2021-08-04 11:42
 */
@RequestMapping("/testMq")
@RestController
public class Testaaaaa {
    @Autowired
    ActivemqOperator activemqOperator;

    @GetMapping("/queue")
    public String testMqQueue() {
        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");//设置日期格式
        System.out.println("当前订单【123456789】生成时间： "+df.format(new Date()));// new Date()为获取当前系统时间
        //设置延时时间推送到activeMQ
        activemqOperator.delaySend("testQueue","延时10S",10000L);
        return "OK";
    }

    @JmsListener(destination = "testQueue", containerFactory = "queueJmsListenerContainerFactory")
    public void listenerMq(String message) {
        //业务逻辑,根据单号查询是否已经付款
        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");//设置日期格式
        System.out.println("当前订单【123456789】失效时间： " + df.format(new Date()));// new Date()为获取当前系统时间
    }
}
