一、安装activeMQ

Linux环境ActiveMQ部署方法：

安装步骤参照上面这篇文章，本文不做介绍

Windows下安装ActiveMQ：

到官网（http://activemq.apache.org/download-archives.html）下载最新发布的压缩包（我下的是5.15.9）到本地后解压（我解压到D盘Dev目录下）即可。进入解压后的bin目录，我是64位机器，再进入win64目录后，双击activemq.bat启动：

默认端口8161，访问下http://localhost:8161/admin，用户名密码都是admin，进入控制台页面：

我们用坐上方的Queues来创建一个叫vboxlog的队列：

二、修改activeMQ配置文件

broker新增配置信息 schedulerSupport="true"

<broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}" schedulerSupport="true" > <destinationPolicy> <policyMap> <policyEntries> <policyEntry topic=">" > <!-- The constantPendingMessageLimitStrategy is used to prevent slow topic consumers to block producers and affect other consumers by limiting the number of messages that are retained For more information, see: http://activemq.apache.org/slow-consumer-handling.html --> <pendingMessageLimitStrategy> <constantPendingMessageLimitStrategy limit="1000"/> </pendingMessageLimitStrategy> </policyEntry> </policyEntries> </policyMap> </destinationPolicy>

三、创建SpringBoot工程

1、配置ActiveMQ工厂信息，信任包必须配置否则会报错

package com.example.demoactivemq.config;import org.apache.activemq.ActiveMQConnectionFactory;import org.apache.activemq.RedeliveryPolicy;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;/** * @author shanks on 2019-11-12 */@Configurationpublic 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.example.demoactivemq.domain"); factory.setTrustedPackages(models); return factory; }}

消息实体类

package com.example.demoactivemq.domain;import lombok.Builder;import lombok.Data;import java.io.Serializable;/** * @author shanks on 2019-11-12 */@Builder@Datapublic class MessageModel implements Serializable { private String titile; private String message;}

生产者

package com.example.demoactivemq.producer;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;/** * 消息生产者 * * @author shanks */@Service@Slf4jpublic class Producer { public static final Destination DEFAULT_QUEUE = new ActiveMQQueue("delay.queue"); @Autowired private JmsMessagingTemplate template; /** * 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) { template.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 = template.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(); } } }}

消费者

package com.example.demoactivemq.producer;import com.example.demoactivemq.domain.MessageModel;import lombok.extern.slf4j.Slf4j;import org.springframework.jms.annotation.JmsListener;import org.springframework.stereotype.Component;/** * 消费者 */@Component@Slf4jpublic class Consumer { @JmsListener(destination = "delay.queue") public void receiveQueue(MessageModel message) { log.info("收到消息:{}", message); }}

application.yml

spring: activemq: broker-url: tcp://localhost:61616

测试类

package com.example.demoactivemq;import com.example.demoactivemq.domain.MessageModel;import com.example.demoactivemq.producer.Producer;import org.junit.jupiter.api.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.test.context.SpringBootTest;import org.springframework.test.context.junit4.SpringRunner;@SpringBootTest(classes = DemoActivemqApplication.class)@RunWith(SpringRunner.class)class DemoActivemqApplicationTests { /** * 消息生产者 */ @Autowired private Producer producer; /** * 及时消息队列测试 */ @Test public void test() { MessageModel messageModel = MessageModel.builder() .message("测试消息") .titile("消息000") .build(); // 发送消息 producer.send(Producer.DEFAULT_QUEUE, messageModel); } /** * 延时消息队列测试 */ @Test public void test2() { for (int i = 0; i < 5; i++) { MessageModel messageModel = MessageModel.builder() .titile("延迟10秒执行") .message("测试消息" + i) .build(); // 发送延迟消息 producer.delaySend(Producer.DEFAULT_QUEUE, messageModel, 10000L); } try { // 休眠100秒，等等消息执行 Thread.currentThread().sleep(100000L); } catch (InterruptedException e) { e.printStackTrace(); } }}
