springboot整合activeMQ之主题（生成者，消费者）

一、pom依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

    <parent>

    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-activemq</artifactId>
            <version>2.1.5.RELEASE</version>
        </dependency>
        <dependency>

            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>


        <dependency>

            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>5.0.4.RELEASE</version>
        </dependency>

            <artifactId>junit</artifactId>
            <scope>test</scope>
        </dependency>


    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

二、配置文件

server:
  port: 8001

spring:
  activemq:
    broker-url: tcp://192.168.56.10:61616 #用自己的MQ服务器地址
    user: admin
    password: admin
  jms:
    pub-sub-domain: true #默认开启的是false 即为queue模式 / true为topic模式

mytopic: active-produce-topic

三、配置类

package activemq.produce.config;

import org.apache.activemq.command.ActiveMQQueue;
import org.apache.activemq.command.ActiveMQTopic;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.jms.annotation.EnableJms;
import org.springframework.stereotype.Component;

import javax.jms.Queue;
import javax.jms.Topic;

@Component
@EnableJms
public class Beanconfig {
    
    

    @Value("${mytopic}")
    private String mytopic;

    @Bean
    public Topic topic(){
    
    
        return new ActiveMQTopic(mytopic);
    }




}

四、生产者

package activemq.produce.Bean;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import javax.jms.Topic;
import java.util.UUID;

@Component //定义组件
public class Produce_topic {
    
    

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    @Autowired
    private Topic topic;

    @Scheduled(fixedDelay = 3000) //设置定时发布
    public void produce(){
    
    
        jmsMessagingTemplate.convertAndSend(topic,"-----"+ UUID.randomUUID().toString().substring(0,6));

    }

}

五、消费者

package activemq.produce.Bean;

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

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

@Component
public class consumer_topic {
    
    

    @JmsListener(destination = "${mytopic}") //消费者设置监听程序
    public void consume(TextMessage textMessage) throws JMSException {
    
    
        System.out.println("接收的消息"+textMessage.getText());
    }
}

六、主程序

@EnableScheduling:开启对@Scheduled的识别

package activemq.produce;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

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

七、测试类

首先打开activemq控制台

• 启动主程序
  

• 可以看出随着信息的发布消费者不断地接收数据
