1、修改mq配置文件 activemq.xml

 <broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}" schedulerSupport="true">

添加上

schedulerSupport="true"

2、pom文件添加

 <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-pool</artifactId>
            <version>5.16.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-all</artifactId>
            <version>5.16.0</version>
        </dependency>

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

3、springboot配置文件添加

spring.activemq.broker-url=tcp://localhost:61616
spring.activemq.in-memory=true
spring.activemq.pool.enabled=false
spring.activemq.password=admin
spring.activemq.user=admin

4、添加MQ代码配置  必须步骤

package com.zsj.daka.daka.config;

import org.apache.activemq.ActiveMQConnectionFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import java.util.ArrayList;
import java.util.List;

/**
 * @Description TODO
 * @Date 2020/9/2 18:04
 * @Author zsj
 */
@Configuration
public class ActiveMqConfig {

    @Bean
    public ActiveMQConnectionFactory factory(@Value("${spring.activemq.broker-url}") String url){
        ActiveMQConnectionFactory factory = new ActiveMQConnectionFactory(url);
        // 设置信任序列化包集合
        List<String> models = new ArrayList<>();
        models.add("com.zsj.daka.daka.model");
        factory.setTrustedPackages(models);

        return factory;
    }

}

5、消息类

package com.zsj.daka.daka.model;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.io.Serializable;

/**
 * @Description TODO
 * @Date 2020/9/2 17:56
 * @Author zsj
 */
@Data
@Builder
@AllArgsConstructor
@NoArgsConstructor
public class MessageModel implements Serializable {

    private String message;

    private String title;
}

6、消息生产者

package com.zsj.daka.daka.quartz;

/**
 * @Description TODO
 * @Date 2020/9/2 17:43
 * @Author zsj
 */

import lombok.extern.slf4j.Slf4j;
import org.apache.activemq.ScheduledMessage;
import org.apache.activemq.command.ActiveMQQueue;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.jms.JmsProperties;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.stereotype.Service;

import javax.jms.*;
import java.io.Serializable;

@Slf4j
@Service("producer")
public class Producer {
    @Autowired // 也可以注入JmsTemplate，JmsMessagingTemplate对JmsTemplate进行了封装
    private JmsMessagingTemplate jmsTemplate;


    /**
     * 发送消息
     *
     * @param destination destination是发送到的队列
     * @param message     message是待发送的消息
     */
    public <T extends Serializable> void send(Destination destination, T message) {
        jmsTemplate.convertAndSend(destination, message);
    }

    /**
     * 延时发送
     *
     * @param destination 发送的队列
     * @param data        发送的消息
     * @param time        延迟时间
     */
    public <T extends Serializable> void delaySend(Destination destination, T data, Long time) {
        Connection connection = null;
        Session session = null;
        MessageProducer producer = null;
        // 获取连接工厂
        ConnectionFactory connectionFactory = jmsTemplate.getConnectionFactory();
        try {
            // 获取连接
            connection = connectionFactory.createConnection();
            connection.start();
            // 获取session，true开启事务，false关闭事务
            session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
            // 创建一个消息队列
            producer = session.createProducer(destination);
            producer.setDeliveryMode(JmsProperties.DeliveryMode.PERSISTENT.getValue());
            ObjectMessage message = session.createObjectMessage(data);
            //设置延迟时间
            message.setLongProperty(ScheduledMessage.AMQ_SCHEDULED_DELAY, time);
            // 发送消息
            producer.send(message);
            log.info("发送消息：{}", data);
            session.commit();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            try {
                if (producer != null) {
                    producer.close();
                }
                if (session != null) {
                    session.close();
                }
                if (connection != null) {
                    connection.close();
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

}

7、消息消费者

package com.zsj.daka.daka.quartz;

/**
 * @Description TODO
 * @Date 2020/9/2 17:44
 * @Author zsj
 */

import com.zsj.daka.daka.model.MessageModel;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.messaging.handler.annotation.SendTo;
import org.springframework.stereotype.Component;

import java.util.Date;


@Component
public class Consumer {

    // 使用JmsListener配置消费者监听的队列，其中text是接收到的消息
    @JmsListener(destination = "mytest.queue")
    public void receiveQueue(MessageModel messageModel) throws InterruptedException {
        System.out.println("consumer接收到"+messageModel.getTitle()+"的请求并处理完毕，时间是"+new Date());
    }


}

8、生产消息入口

package com.zsj.daka.daka.quartz;

import com.zsj.daka.daka.model.MessageModel;
import org.apache.activemq.command.ActiveMQQueue;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.jms.Destination;

/**
 * @Description TODO
 * @Date 2020/9/2 17:44
 * @Author zsj
 */
@Controller
public class UserController {
    @Autowired
    private Producer producer;

    /**
     * 消息队列实现方式
     */
    @RequestMapping("/queue")
    @ResponseBody
    public String queue() {
        Destination destination = new ActiveMQQueue("mytest.queue");

        for (int i = 0; i < 10; i++) {
            MessageModel messageModel = MessageModel.builder()
                    .message("测试消息" + i)
                    .title("消息" + i)
                    .build();
            // 发送消息
            producer.send(destination, messageModel);
        }

        return "queue 发送成功";
    }

    @RequestMapping("/delay")
    @ResponseBody
    public String delay() {
        Destination destination = new ActiveMQQueue("mytest.queue");

        for (int i = 0; i < 10; i++) {
            MessageModel messageModel = MessageModel.builder()
                    .message("测试消息" + i)
                    .title("消息" + i)
                    .build();
            // 延时发送消息 单位毫秒
            producer.delaySend(destination, messageModel,60*1000L);
        }

        return "delay 发送成功";
    }

}
