Create Maven projects, pom.xml consistent with the above producers

springboot arrangement, application.yml:

server:
  port: 5566
spring:
  activemq:
    broker-url: tcp://localhost:61616 #自己的MQ服务器地址
    user: admin
    password: admin

  jms:
    pub-sub-domain: true    # false: Queue  true：Topic


#自己定义队列名称
mytopic: boot-activemq-topic

consumer:

package pers.zhang.activemq;

import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;

import javax.jms.JMSException;
import javax.jms.TextMessage;

@Component
public class Queue_Consumer {

    @JmsListener(destination = "${mytopic}")
    public void receive(TextMessage textMessage)throws JMSException {
        System.out.println("消费者收到主题的消息：" + textMessage.getText());
    }
}

Master Boot categories:

@SpringBootApplication
public class MainApp_Consumer {
    public static void main(String[] args) {
        SpringApplication.run(MainApp_Consumer.class, args);
    }

Consumers first start:

Then start producers, a message is sent every 2 seconds:

Consumers Print Console:
