生产者Queue

队列生产者代码：

package com.huazai.activemq.spring.queue;

import org.apache.xbean.spring.context.ClassPathXmlApplicationContext;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Service;

import java.util.Scanner;

/**

 * @date 2022/01/11 23:39
 */
@Service
public class SpringMQProducer {
   
     
    static final Scanner input = new Scanner(System.in);

    @Autowired
    private final JmsTemplate jmsTemplate;

    @Autowired
    public SpringMQProducer(JmsTemplate jmsTemplate) {
   
     
        this.jmsTemplate = jmsTemplate;
    }

    public static void main(String[] args) {
   
     
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
        SpringMQProducer springMQ_producer = applicationContext.getBean(SpringMQProducer.class);
        JmsTemplate jmsTemplate = springMQ_producer.jmsTemplate;
        // 发送消息
        jmsTemplate.send(session -> session.createTextMessage("***Spring和ActiveMQ的整合case....."));
        System.out.println("********send task over");
        while(true) {
   
     
            System.out.println("\n请输入要发送的内容");
            final String msgText = input.next();
            // 输入exit推出程序
            if ("exit".equals(msgText)) {
   
     
                System.exit(-1);
            }
            if (msgText.startsWith("auto:")) {
   
     
                int amount;
                try {
   
     
                    amount = Integer.parseInt(msgText.substring(5));
                } catch (NumberFormatException e) {
   
     
                    System.out.println("auto指令格式错误，正确的应该是：auto:number");
                    continue;
                }
                System.out.println("请稍等...");
                for (int i = 1; i <= amount; i++) {
   
     
                    final int ii = i;
                    jmsTemplate.send(session -> session.createTextMessage(ii + ""));
                }
                System.out.println(msgText + "\t->|\t指令执行完成");
            } else {
   
     
                jmsTemplate.send(session -> session.createTextMessage(msgText));
                System.out.println(msgText + "\t->|\t发送完成");
            }
        }
    }
}

队列消费者代码：

package com.huazai.activemq.spring.queue;

import org.apache.xbean.spring.context.ClassPathXmlApplicationContext;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Service;

/**
 * @author DDKK.COM 弟弟快看，程序员编程资料站
 * @date 2022/01/11 23:39
 */
@Service
public class SpringMQConsumer {
   
     
    @Autowired
    private JmsTemplate jmsTemplate;

    @Autowired
    public void setJmsTemplate(JmsTemplate jmsTemplate) {
   
     
        this.jmsTemplate = jmsTemplate;
    }

    public static void main(String[] args) {
   
     
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
        SpringMQConsumer springMQConsumer = applicationContext.getBean(SpringMQConsumer.class);
        while(true) {
   
     
            // 接受消息
            String returnValue = (String) springMQConsumer.jmsTemplate.receiveAndConvert();
            // 输入exit-退出
            if ("exit-".equals(returnValue)) {
   
     
                System.exit(-1);
            }
            System.out.println("****消费者收到的消息: " + returnValue);
        }
    }
}

启动消费者和订阅者，结果如下：

 

 

生产者Topic

增加核心配置

<!--主题-->
<bean id="destinationTopic" class="org.apache.activemq.command.ActiveMQTopic">
    <constructor-arg index="0" value="spring-active-topic"></constructor-arg>
</bean>

 消费者和生产者代码不需要改变
就这 么 简 简 单 单 \color{red}就这么简简单单 就这么简简单单

监听器实现消费者不启动直接消费消息

applicationContext.xml 监听器配置：

<!--  配置Jms消息监听器  -->
<bean id="defaultMessageListenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
    <!--  Jms连接的工厂     -->
    <property name="connectionFactory" ref="connectionFactory"/>
    <!--   设置默认的监听目的地     -->
    <property name="destination" ref="destinationTopic"/>
    <!--传入默认目的地，可以是queue，也可以是topic-->
    <property name="messageListener" ref="myMessageListener"/>
</bean>

自定义监听器：

package com.huazai.activemq.spring.listener;

import org.springframework.stereotype.Component;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;

/**
 * @author DDKK.COM 弟弟快看，程序员编程资料站
 * @date 2022/1/12 0:14
 */
@Component
public class MyMessageListener implements MessageListener {
   
     
    @Override
    public void onMessage(Message message) {
   
     
        if (message instanceof TextMessage) {
   
     
            TextMessage textMessage = (TextMessage) message;
            try {
   
     
                System.out.println("消费者收到的消息" + textMessage.getText());
            } catch (JMSException e) {
   
     
                e.printStackTrace();
            }
        }
    }
}

增加了监听器之后，在原来代码基础上

1、 只启动队列生产者；

 

以上案例实现了不启动消费者通过监听器实现queue和topic消息消费。
