ActiveMQ--整合SpringBoot

  1. 整合队列
    • 队列生产者
      1. 新建maven工程并设置包名类名
        • 工程名：boot_mq_produce
        • 包名:com.model
      2. pom.xml
        1.

      3. application.yaml
        1. 　　 
          server:
  port: 7777
spring:
  activemq:
    broker-url: tcp://192.168.56.130:61616
    user: admin
    password: admin
  jms:
    pub-sub-domain: false  #false = Queue  true = Topic
myqueue: boot-activemq-queue #自定义队列名称

           

      4. 配置Bean：类似spring框架的applicationContext.xml文件
        1. package com.model.config;

import org.apache.activemq.command.ActiveMQQueue;
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;

@EnableJms
@Component
public class ConfigBean {
    @Value("${myqueue}") //读取到了yaml中的值
    private String myQueue;

    @Bean
    public Queue queue(){

            return new ActiveMQQueue(myQueue);
    }
}

           

          　　
      5. Queue_Produce
        1. package com.model.produce;

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

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

@Component
public class Queue_Produce {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    @Autowired
    private Queue queue;

    public void produceMsg(){
        jmsMessagingTemplate.convertAndSend(queue,"********:"+ UUID.randomUUID().toString().substring(0,6));
        
    }
}

           

          　　
      6. 主动启动类MainApp_Produce
        1. 　　 
          package com.model;

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

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

}

           

      7. 测试单元
        1. package com.model.avtivemq;

import com.model.MainApp_Produce;
import com.model.produce.Queue_Produce;
import org.junit.jupiter.api.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 org.springframework.test.context.web.WebAppConfiguration;

import javax.annotation.Resource;
import javax.annotation.security.RunAs;

@SpringBootTest(classes = MainApp_Produce.class)
@WebAppConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
class BootMqProduceApplicationTests {

    @Resource
    private Queue_Produce queue_produce;

    @Test
    public void contextLoads() throws Exception {

        queue_produce.produceMsg();

    }


}

           

        2. 没只执行一次test就会向后台发送一条消息

        3.  

           

          　 　　　
      8. 新要求：要求没隔3秒网MQ中推送消息，以下定时发送Case，案例修改　　
        1. 修改Queue_Produce
          1. 　　 
            package com.model.produce;

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;

@Component
public class Queue_Produce {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    @Autowired
    private Queue queue;

    public void produceMsg(){
        jmsMessagingTemplate.convertAndSend(queue,"********:"+ UUID.randomUUID().toString().substring(0,6));

    }
    @Scheduled(fixedDelay = 3000)//定时投放信息
    public void produceMsgScheduled(){
        jmsMessagingTemplate.convertAndSend(queue,"********:"+ UUID.randomUUID().toString().substring(0,6));
        System.out.println("*********produceMsgScheduled send over!***********");
    }
}

             

        2. 修改主启动类
          1. 　 
            package com.model.produce;

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;

@Component
public class Queue_Produce {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    @Autowired
    private Queue queue;

    public void produceMsg(){
        jmsMessagingTemplate.convertAndSend(queue,"********:"+ UUID.randomUUID().toString().substring(0,6));

    }
    @Scheduled(fixedDelay = 3000)//定时投放信息
    public void produceMsgScheduled(){
        jmsMessagingTemplate.convertAndSend(queue,"********:"+ UUID.randomUUID().toString().substring(0,6));
        System.out.println("*********produceMsgScheduled send over!***********");
    }
}

             

            　
        3. 直接启动主类，间隔发送消息　　

          2.  

             

             

              

            　　
    • 队列消费者
      • 新建maven工程包括工程名和包名
      • pom.xml ：和生产者一样
      • applicationContext.yaml　　 ：修改一下端口号即可
      • Queue_Consumer ： 
        • package com.model.consumer;

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 = "${myqueue}")
    public void receive(TextMessage textMessage) throws JMSException {
        System.out.println("****消费者消费消息："+textMessage.getText());
    }
}
          　
        • 以前我们需要自己配置一个监听器类:配置监听器就可以实现消费者自动给读取消费队列中的消息，不用我们运行一次消费一次，
        • springboot为我们配置一个注解 JmsListener（destination=“队列名称”）：我们只需告诉监听器需要监听那个队列即可实现自动监听机制
      • 主启动类　　　　　　
  2. 整合发布和订阅
    • topic生产者
      1. 新建maven工程并设置包名类名
        1. 工程名：boot_mq_topic_produce
        2. 包名：com.model
      2. pom.xml
      3. applicaiton.yaml
        1. server:
  port: 6666
spring:
  activemq:
    broker-url: tcp://192.168.56.130:61616
    user: admin
    password: admin
  jms:
    pub-sub-domain: true  #false = Queue  true = Topic
myqueue: boot-activemq-queue #自定义队列名称
mytopic: boot-activemq-topic #自定义的topic的名称

           

          　　
      4. 配置Bean：类似spring框架的appliacationContext.xml文件（配置了从配置文件内获取topic名称，根据名称创建一个topic对象并放入到springboot容器中）
        1. 　　 
          package com.model.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;

@EnableJms
@Component
public class ConfigBean {
    @Value("${mytopic}") //读取到了yaml中的值
    private String myTopic;

    @Bean
    public Topic topic(){

            return new ActiveMQTopic(myTopic);
    }
}

           

      5. Topic_Produce（根据容器中的Topic和消息的的装饰类JmsMessgeingTemplate共同修饰，将消息发送发到JMS服务器）
        1. package com.model.produce;

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

@Component
public class Topic_Produce {

    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    @Autowired
    private Topic topic;

    @Scheduled(fixedDelay = 3000)
   public void produceTopic(){

        jmsMessagingTemplate.convertAndSend(topic,"主题消息："+UUID.randomUUID().toString().substring(0,6));
   }
}

           

          　　
      6. 主启动类MainApp_Topic_Produce　　　　
    • topic消费者
      1. 新建maven工程并设置包名类名
        1. 工程名:boot_mq_topic_consumer
        2. 包名：com.model
      2. pom.xml
      3. application.yaml
      4. Topic_Consumer
        1. package com.model.consumer;

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

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

@Component
public class Topic_Consumer {

    @JmsListener(destination = "${mytopic}")//监听topic
    public void receive(TextMessage textMessage) throws JMSException {
        System.out.println("****消费者消费消息："+textMessage.getText());
    }
}

           

          　　
      5. 模拟两个订阅者著启动类，先启动订阅者在启动发布者
        1. MainApp5555
        2. MainApp5566
      6. 先启动消费者，在启动生产者，这里我们启动俩个消费者，消费则会监听对类中的topic

      7.
