ActiveMQ integration of Spring

Foreword

We speak in front of producers and consumers, when coding are relatively basic, time and effort to develop them, let's introduce the future how to integrate the spring to simplify development;

Consolidation Configuration

pom increased reliance:

Queue producers and consumers

package com.chaytech.activemq.spring;

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;

/**
 * activeMQ整合spring-生产者
 *
 * @author Chency
 * @email [email protected]
 * @Date 2020/03/24 21:41
 */
@Service
public class SpringJmsProducer {

    @Autowired
    private JmsTemplate jmsTemplate;

    public static void main(String[] args) {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring-activemq.xml");

        SpringJmsProducer springJmsProducer = (SpringJmsProducer)applicationContext.getBean("springJmsProducer");
        springJmsProducer.jmsTemplate.send((session) -> {
            return session.createTextMessage("spring整合activeMQ。。");
        });
    }
}

package com.chaytech.activemq.spring;

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;

/**
 * activeMQ整合spring-消费者
 *
 * @author Chency
 * @email [email protected]
 * @Date 2020/03/24 21:41
 */
@Service
public class SpringJmsConsumer {

    @Autowired
    private JmsTemplate jmsTemplate;

    public static void main(String[] args) {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring-activemq.xml");

        SpringJmsConsumer springJmsConsumer = (SpringJmsConsumer)applicationContext.getBean("springJmsConsumer");

        String message = (String) springJmsConsumer.jmsTemplate.receiveAndConvert();
        System.out.println("spring整合activeMQ消费者：" + message);
    }
}

Theme producers and consumers

Theme producers and consumers without changing the code, just modify the configuration files, amended as follows:

 <!--  这个是队列目的地,  发布订阅的主题Topic-->
<bean id="destinationTopic" class="org.apache.activemq.command.ActiveMQTopic">
    <constructor-arg index="0" value="spring-active-topic"/>
</bean>

<!--  Spring提供的JMS工具类,他可以进行消息发送,接收等  -->
<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
    <!--    传入连接工厂    -->
    <property name="connectionFactory" ref="connectionFactory"/>
    <!--    传入目的地    -->
    <!--<property name="defaultDestination" ref="destinationQueue"/>-->
    <property name="defaultDestination" ref="destinationTopic"/>
    <!--    消息自动转换器    -->
    <property name="messageConverter">
        <bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/>
    </property>
</bean>

Increases topic destination and point jmsTemplate in defaultDestination our new destinationTopic

Consumers listeners

Front blocking the way we consume news when consumers use, the following will demonstrate how to use the Listener way to consume news, once the listener configuration, you need to start a consumer, the producer at the time of sending messages, listening automatically consumption

First, we must first define a custom message listener:

package com.chaytech.activemq.spring;

import org.springframework.stereotype.Component;

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

/**
 * 自定义消息监听器
 *
 * @author Chency
 * @email [email protected]
 * @Date 2020/03/24 22:05
 */
@Component
public class CustomerMessageListener implements MessageListener {

    @Override
    public void onMessage(Message message) {
        if(message != null && message  instanceof TextMessage){
            TextMessage textMessage = (TextMessage) message;
            try {
                System.out.println("自定义消息监听器监听到的消息：" + textMessage.getText());
            } catch (JMSException e) {
                e.printStackTrace();
            }
        }
    }
}

Modify the configuration file, add the listener configuration:

<!--配置消费者监听器-->
<bean id="messageListenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
    <property name="connectionFactory" ref="connectionFactory"/>
    <property name="destination" ref="destinationTopic"/>
    <property name="messageListener" ref="customerMessageListener"/>
</bean>
