一、安装activeMQ

Linux环境ActiveMQ部署方法：https://www.nhooo.com/article/162320.htm

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"

">

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

packagecom.example.demoactivemq.config;

importorg.apache.activemq.ActiveMQConnectionFactory;
importorg.apache.activemq.RedeliveryPolicy;
importorg.springframework.beans.factory.annotation.Value;
importorg.springframework.context.annotation.Bean;
importorg.springframework.context.annotation.Configuration;

importjava.util.ArrayList;
importjava.util.List;

/**
*@authorshankson2019-11-12
*/
@Configuration
publicclassActiveMqConfig{

@Bean
publicActiveMQConnectionFactoryfactory(@Value("${spring.activemq.broker-url}")Stringurl){
ActiveMQConnectionFactoryfactory=newActiveMQConnectionFactory(url);
//设置信任序列化包集合
Listmodels=newArrayList<>();
models.add("com.example.demoactivemq.domain");
factory.setTrustedPackages(models);

returnfactory;
}

}

消息实体类

packagecom.example.demoactivemq.domain;

importlombok.Builder;
importlombok.Data;

importjava.io.Serializable;

/**
*@authorshankson2019-11-12
*/

@Builder
@Data
publicclassMessageModelimplementsSerializable{
privateStringtitile;
privateStringmessage;
}

生产者

packagecom.example.demoactivemq.producer;


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

importjavax.jms.*;
importjava.io.Serializable;


/**
*消息生产者
*
*@authorshanks
*/
@Service
@Slf4j
publicclassProducer{

publicstaticfinalDestinationDEFAULT_QUEUE=newActiveMQQueue("delay.queue");

@Autowired
privateJmsMessagingTemplatetemplate;

/**
*发送消息
*
*@paramdestinationdestination是发送到的队列
*@parammessagemessage是待发送的消息
*/
publicvoidsend(Destinationdestination,Tmessage){
template.convertAndSend(destination,message);
}

/**
*延时发送
*
*@paramdestination发送的队列
*@paramdata发送的消息
*@paramtime延迟时间
*/
publicvoiddelaySend(Destinationdestination,Tdata,Longtime){
Connectionconnection=null;
Sessionsession=null;
MessageProducerproducer=null;
//获取连接工厂
ConnectionFactoryconnectionFactory=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());
ObjectMessagemessage=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(Exceptione){
e.printStackTrace();
}finally{
try{
if(producer!=null){
producer.close();
}
if(session!=null){
session.close();
}
if(connection!=null){
connection.close();
}
}catch(Exceptione){
e.printStackTrace();
}
}
}
}

消费者

packagecom.example.demoactivemq.producer;


importcom.example.demoactivemq.domain.MessageModel;
importlombok.extern.slf4j.Slf4j;
importorg.springframework.jms.annotation.JmsListener;
importorg.springframework.stereotype.Component;

/**
*消费者
*/
@Component
@Slf4j
publicclassConsumer{


@JmsListener(destination="delay.queue")
publicvoidreceiveQueue(MessageModelmessage){
log.info("收到消息:{}",message);
}
}

application.yml

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

测试类

packagecom.example.demoactivemq;

importcom.example.demoactivemq.domain.MessageModel;
importcom.example.demoactivemq.producer.Producer;
importorg.junit.jupiter.api.Test;
importorg.junit.runner.RunWith;
importorg.springframework.beans.factory.annotation.Autowired;
importorg.springframework.boot.test.context.SpringBootTest;
importorg.springframework.test.context.junit4.SpringRunner;

@SpringBootTest(classes=DemoActivemqApplication.class)
@RunWith(SpringRunner.class)
classDemoActivemqApplicationTests{

/**
*消息生产者
*/
@Autowired
privateProducerproducer;

/**
*及时消息队列测试
*/
@Test
publicvoidtest(){
MessageModelmessageModel=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
publicvoidtest2(){
for(inti=0;i<5;i++){
MessageModelmessageModel=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(InterruptedExceptione){
e.printStackTrace();
}
}
}
