 */
@Component
public class MyProvider {
    //注入JMSTemplate模板
    @Resource
    private JmsTemplate jmsTemplate;
    //创建方法
    public void sendMessage(){
        //点对点,创建队列
        ActiveMQQueue queue=new ActiveMQQueue("SpringBoot_Queue");

    @Bean
    public JmsListenerContainerFactory jmsTopicListenerContainerFactory(ConnectionFactory connectionFactory){
        DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
        factory.setConnectionFactory(connectionFactory);
        //这里必须设置为true,false则表示是queue类型
        factory.setPubSubDomain(true);
        return factory;
    }


    //消费者消费  destination队列或者主题的名字
    @JmsListener(destination = "SpringBoot_Topic",containerFactory = "jmsTopicListenerContainerFactory")

    <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-activemq</artifactId>
    </dependency>

7、TopicProvider

package com.zn.topic;

import org.apache.activemq.command.ActiveMQQueue;
import org.apache.activemq.command.ActiveMQTopic;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;

/**
 * 生产者,通过JMSTemplate模板发送消息
 */
@Component
public class TopicProvider {
    //注入JMSTemplate模板
    @Resource
    private JmsTemplate jmsTemplate;
    //创建方法
    public void sendMessage(){
        //发布订阅,创建主题
        ActiveMQTopic topic=new ActiveMQTopic("SpringBoot_Topic");
        //springboot默认是queue
        jmsTemplate.setPubSubDomain(true);
        //发送消息
        jmsTemplate.convertAndSend(topic,"生产者产生topic的消息");
    }
}

8、ProvideController

package com.zn.controller;

import com.zn.p2p.MyProvider;
import com.zn.topic.TopicProvider;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.annotation.Resource;

/**
 * 客户端访问的方法
 */
@RestController
public class ProvideController {

    //topic调用
    @Resource
    private TopicProvider topicProvider;

    @RequestMapping("/sendMessage")
    public String sendMessage(){
        topicProvider.sendMessage();
        return "success";
    }
}

9、启动消费者订阅消息

  

10、启动生产者

  

   

 11、消费者控制台效果

  

三、SpringBoot整合ActiveMQ开启持久化---队列持久化

1、步骤1、2、3同上p2p

4、生产者MyProvider,通过JMSTemplate模板发送消息

package com.zn.p2p;

import org.apache.activemq.command.ActiveMQQueue;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;

/**
 * 生产者,通过JMSTemplate模板发送消息
 */
@Component
public class MyProvider {
    //注入JMSTemplate模板
    @Resource
    private JmsTemplate jmsTemplate;
    //创建方法
    public void sendMessage(){

        //开启持久化
        jmsTemplate.setDeliveryMode(2);
        jmsTemplate.setExplicitQosEnabled(true);
        jmsTemplate.setDeliveryPersistent(true);


        //点对点,创建队列
        ActiveMQQueue queue=new ActiveMQQueue("SpringBoot_Queue");
        //发送消息
        jmsTemplate.convertAndSend(queue,"生产者产生的消息");
    }
}

5、步骤5、6、7、8、9、10同上

11、开启生产者

  

  

  

12、开启消费者

  

     

  这里可以试一下让ActiveMQ服务器宕机,然后让服务器重启,看看数据有没有做持久化的操作

13、结论:当服务器宕机,重启服务器之后,没有被消费的消息依然在数据库中,这样就做到了持久化操作。

四、SpringBoot整合ActiveMQ开启持久化---主题持久化

  不会进行数据消费的,但是数据可以持久化

1、步骤1、2、3同上

4、consumer启动类StartTopicConsumer

package com.zn;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.jms.config.DefaultJmsListenerContainerFactory;
import org.springframework.jms.config.JmsListenerContainerFactory;
import org.springframework.jms.listener.DefaultMessageListenerContainer;

import javax.jms.ConnectionFactory;
import javax.jms.JMSException;
import javax.jms.Session;
import javax.jms.TextMessage;

@SpringBootApplication
public class StartTopicConsumer {
    public static void main(String[] args) {
        SpringApplication.run(StartTopicConsumer.class,args);
    }
@Bean(name
= "topicListenerFactory") public JmsListenerContainerFactory<DefaultMessageListenerContainer> topicListenerFactory(ConnectionFactory connectionFactory){ DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory(); factory.setSubscriptionDurable(true);// Set this to "true" to register a durable subscription, factory.setClientId("A"); factory.setConnectionFactory(connectionFactory); return factory; } //消费者消费 destination队列或者主题的名字 @JmsListener(destination = "boot_topic",containerFactory = "topicListenerFactory") public void getMessage(TextMessage message, Session session) throws JMSException { System.out.println("消费者获取到消息:"+message.getText()); } }

9、步骤5、6、7、8同上

10、启动消费者

  

11、启动生产者

  

  

   

12、消费者控制台
