环境启动配置和代码
- application.yml配置:
server:
port: 7777
spring:
activemq:
你的activemq连接地址
broker-url: tcp://192.168.64.129:61616
账号
user: admin
密码
password: admin
jms:
指定连接的是队列(Queue)还是主题(Topic),false代表队列,true代表主题
pub-sub-domain: false
queue:
name: boot-queue-test
topic:
name: boot-topic-test
ActiveMQ配置类:
package com.huazai.activemq.springboot.config;
import org.apache.activemq.command.ActiveMQQueue;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import javax.jms.Queue;
/**
* @author DDKK.COM 弟弟快看,程序员编程资料站
* @date 2022/1/16 19:13
*/
@Configuration
public class ActiveConfig {
@Value("${queue.name}")
private String queueName;
@Value("${topic.name}")
private String topicName;
@Bean
public Queue activeQueue() {
return new ActiveMQQueue(queueName);
}
@Bean
public Topic activeTopic() {
return new ActiveMQTopic(topicName);
}
}
- 启动类:
package com.huazai.activemq.springboot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.jms.annotation.EnableJms;
/**
* @author DDKK.COM 弟弟快看,程序员编程资料站
* @date 2022/1/16 18:51
*/
@SpringBootApplication
// 开启JMS服务
@EnableJms
public class BootQueueProviderMain {
public static void main(String[] args) {
SpringApplication.run(BootQueueProviderMain.class, args);
}
}
队列生产者代码
- 消息生产者服务:
package com.huazai.activemq.springboot.queue;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Service;
import javax.jms.JMSException;
import javax.jms.Queue;
import java.util.UUID;
@Service
public class QueueProviderService {
/**
* 相当于 {@link JmsTemplate}
*/
@Autowired
private JmsMessagingTemplate jmsMessagingTemplate;
@Autowired
private Queue queue;
/**
* 生产消息
*
* @throws JMSException
*/
@JmsListener(destination = "${queue.name}")
public void productMessage() throws JMSException {
// 生产者生产并发送消息,此方法是send方法的加强版
jmsMessagingTemplate.convertAndSend(queue, "消费者发送消息:" + UUID.randomUUID());
}
}
- 队列消息发送测试类:
import com.huazai.activemq.springboot.BootQueueProviderMain;
import com.huazai.activemq.springboot.queue.QueueProviderService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import javax.jms.JMSException;
/**
* @author DDKK.COM 弟弟快看,程序员编程资料站
* @date 2022/1/16 19:25
*/
@SpringBootTest(classes = BootQueueProviderMain.class)
@RunWith(SpringJUnit4ClassRunner.class)
public class QueueProviderTest {
@Autowired
private QueueProviderService queueProviderService;
@Test
public void testSend() throws JMSException {
queueProviderService.productMessage();
}
}
启动测试类,将消息发送到名称为boot-queue-test
队列,结果如下:
队列消费者代码
- 消息监听消费服务:
package com.huazai.activemq.springboot.queue;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Service;
import javax.jms.JMSException;
import javax.jms.TextMessage;
@Service
public class QueueConsumerService {
/**
* 监听接收的方法,监听的目的地名称为${queue.name}配置
*/
@JmsListener(destination = "${queue.name}")
public void receive(TextMessage textMessage) throws JMSException {
String text = textMessage.getText();
System.out.println("***消费者收到的消息: " + text);
}
}
启动消费者服务,接受到了之前生产者生产的消息,测试结果如下:
主题代码
- 主题订阅者服务
package com.huazai.activemq.springboot.topic;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Service;
import javax.jms.Topic;
import java.util.UUID;
/**
* @author DDKK.COM 弟弟快看,程序员编程资料站
* @date 2022/1/17 15:14
*/
@Service
public class TopicProviderService {
@Autowired
private JmsMessagingTemplate jmsMessagingTemplate;
@Autowired
private Topic topic;
/**
* 每隔3秒定时发布主题消息
*/
@Scheduled(fixedDelay = 3000)
public void productTopic() {
jmsMessagingTemplate.convertAndSend(topic, "发布者发布主题消息:" + UUID.randomUUID());
}
}
- 主题发布者服务
package com.huazai.activemq.springboot.topic;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Service;
import javax.jms.JMSException;
import javax.jms.TextMessage;
/**
* @author DDKK.COM 弟弟快看,程序员编程资料站
* @date 2022/1/17 15:15
*/
@Service
public class TopicConsumerService {
/**
* 开启监听器监听主题消息
*
* @param textMessage
* @throws JMSException
*/
@JmsListener(destination = "${topic.name}")
public void receive(TextMessage textMessage) throws JMSException {
String text = textMessage.getText();
System.out.println("订阅者订阅到的消息:" + text);
}
}
先启动主题订阅者,再启动主题发布者,主题订阅者会间隔3秒接收到主题发布者的消息,结果如下:
