News producer

Producer application.yml:

server:
    port: 8081 # 端口号

spring:
    activemq:
        # activemq的broker的url
        broker-url: tcp://192.168.0.166:61616
        # 连接activemq的broker所需的账号和密码
        user: admin
        password: admin
    jms:
        # 目的地是queue还是topic， false（默认） = queue    true =  topic
        pub-sub-domain: false

#  自定义队列名称。这只是个常量
queueName: boot-activemq-queue

# 主题名称
topicName: boot-activemq-topic

Producers configuration class:

package com.chaytech.producer;

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;

@Component
@EnableJms // 开启jms
public class Config {

    @Value("${queueName}")
    private String queueName;
    @Value("${topicName}")
    private String topicName;

    @Bean
    public ActiveMQQueue activeMQQueue(){
        return new ActiveMQQueue(queueName);
    }

    @Bean
    public ActiveMQTopic activeMQTopic(){
        return new ActiveMQTopic(topicName);
    }
}

Manufacturer messaging Controller:

package com.chaytech.producer;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

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

/**
 * 消息生产者
 *
 * @author Chency
 * @email [email protected]
 * @Date 2020/03/25 20:55
 */
@RestController
@RequestMapping("/producer")
public class ProducerController {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;
    @Autowired
    private Queue queue;
    @Autowired
    private Topic topic;

    /**
     * 发送队列消息
     *
     * @param msg
     */
    @GetMapping("/sendQueueMessage/{msg}")
    public void sendQueueMessage(@PathVariable String msg){
        jmsMessagingTemplate.convertAndSend(this.queue, msg);
    }

    /**
     * 发送主题消息
     *
     * @param msg
     */
    @GetMapping("/sendTopicMessage/{msg}")
    public void sendTopicMessage(@PathVariable String msg){
        jmsMessagingTemplate.convertAndSend(this.topic, msg);
    }
}

package com.chaytech;

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

/**
 * 生产者启动类
 *
 * @author Chency
 * @email [email protected]

@SpringBootApplication
public class ProducerApplication {

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

Consumer news

Consumers application.yml:

server:
  port: 8091 # 端口号
spring:
  activemq:
    # activemq的broker的url
    broker-url: tcp://192.168.0.166:61616
    # 连接activemq的broker所需的账号和密码
    user: admin
    password: admin
  jms:
    # 目的地是queue还是topic， false（默认） = queue    true =  topic
    pub-sub-domain: false

#  自定义队列名称。这只是个常量
queueName: boot-activemq-queue

# 主题名称
topicName: boot-activemq-topic

Consumers message listener, when the producer has issued a new message, here are automatically consumption:

package com.chaytech.consumer;

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

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

/**
 * 消费者消息监听器
 *
 * @author Chency
 * @email [email protected]
 * @Date 2020/03/25 21:14
 */
@Component
public class ConsumerListener {

    @JmsListener(destination = "${queueName}")
    public void receiveQueueMsg(TextMessage textMessage) throws JMSException {
        System.out.println("消费者监听到的队列消息：" + textMessage.getText());
    }

    @JmsListener(destination = "${topicName}")
    public void receiveTopicMsg(TextMessage textMessage) throws JMSException {
        System.out.println("消费者监听到的主题消息：" + textMessage.getText());
    }
}

Start categories:

package com.chaytech;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * 消费者启动类
 *
 * @author Chency
 * @email [email protected]
 * @Date 2020/03/25 21:11
 */
@SpringBootApplication
public class ConsumerApplication {

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

Switching the message queue message theme

We are in front of the queue to which a message that if the need to send a message theme, how to do it?
We only need to modify configuration files producers and consumers as well as the destination when sending a message directed to Topic:

# 目的地是queue还是topic， false（默认） = queue    true =  topic
spring.jms.pub-sub-domain: false

package com.chaytech.producer;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

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

/**
 * 消息生产者
 *
 * @author Chency
 * @email [email protected]
 * @Date 2020/03/25 20:55
 */
@RestController
@RequestMapping("/producer")
public class ProducerController {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;
    @Autowired
    private Topic topic;
    
    /**
     * 发送主题消息
     *
     * @param msg
     */
    @GetMapping("/sendTopicMessage/{msg}")
    public void sendTopicMessage(@PathVariable String msg){
        jmsMessagingTemplate.convertAndSend(this.topic, msg);
    }
}

Timing message delivery

Earlier we talked about are triggered message delivery, then activeMQ also supports regular message delivery, sample code as follows:

package com.chaytech.producer;

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.Queue;
import java.util.UUID;

/**
 * 定时投递消息
 *
 * @author Chency
 * @email [email protected]
 * @Date 2020/03/25 21:07
 */
@Component
public class ProducerScheduled {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;
    @Autowired
    private Queue queue;

    /**
     * 定时投递消息，间隔3秒
     */
    @Scheduled(fixedDelay = 3000)
    public void scheduledSendQueueMessage(){
        jmsMessagingTemplate.convertAndSend(this.queue, "定时投递消息 —> " + UUID.randomUUID());
    }
}

Modifying the boot type, the opening timing of delivery:

package com.chaytech;

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

/**
 * 生产者启动类
 *
 * @author Chency
 * @email [email protected]
 * @Date 2020/03/25 21:04
 */
@SpringBootApplication
@EnableScheduling // 开启定时投递消息
public class ProducerApplication {

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