        SpringMQProduce produce = ctx.getBean(SpringMQProduce.class);

        // 由于 目标队列 在配置文件指定了，所以在发送的时候不需要再指定
        produce.jmsTemplate.send(new MessageCreator() {
            @Override
            public Message createMessage(Session session) throws JMSException {

        System.out.println("spring消费者收到的消息：" + retValue);
    }

}

    <!--  配置生产者  -->
    <bean id="connectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop">
        <property name="connectionFactory">

        </property>
    </bean>
</beans>

3.2 生产者

  • 和队列的代码一样，只是在配置文件里面改了destination

3.3 消费者

  • 和队列的代码一样，只是在配置文件里面改了destination

4.消费者 - 监听器

  • 实现目标：在Spring里面实现消费者不启动，直接通过配置监听完成
  • 类似于前面setMessageListenner实时间提供消息
  • 注意：配置了监听器，那么启动生产者，就会自动消费，不需要再启动消费者了

4.1 编写监听器类

package com.qingsi.activemq.spring;

import org.springframework.stereotype.Component;

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

@Component
public class MyMessageListener implements MessageListener {
    @Override
    public void onMessage(Message message) {
        if (message instanceof TextMessage){
            TextMessage textMessage = (TextMessage) message;
            try {
                System.out.println("收到消息： " + textMessage.getText());
            } catch (JMSException e) {
                e.printStackTrace();
            }
        }
    }
}

4.2 配置监听器

  • applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">

    <!--  开启包的自动扫描  -->
    <context:component-scan base-package="com.qingsi.activemq"/>
    <!--  配置生产者  -->
    <bean id="connectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop">
        <property name="connectionFactory">
            <!--      正真可以生产Connection的ConnectionFactory,由对应的JMS服务商提供  -->
            <bean class="org.apache.activemq.spring.ActiveMQConnectionFactory">
                <property name="brokerURL" value="tcp://192.168.86.128:61616"/>
            </bean>
        </property>
        <property name="maxConnections" value="100"/>
    </bean>

    <!--  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="destinationTopic"/>
        <!--    消息自动转换器    -->
        <property name="messageConverter">
            <bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/>
        </property>
    </bean>

    <!--  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"/>
        <!--  指定自己实现了MessageListener的类     -->
        <property name="messageListener" ref="myMessageListener"/>
    </bean>
</beans>

4.3 生产者+消费者一体

package com.qingsi.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.jms.core.MessageCreator;
import org.springframework.stereotype.Service;

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

@Service
public class SpringMQProduce {
    @Autowired
    private JmsTemplate jmsTemplate;

    public static void main(String[] args) {
        // 获取配置文件对象
        ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
        // 获取SpringMQProduce对象，用于调用jmsTemplate
        // 下面等同于 new SpringMQProduce()，但是交给Spring管理，他只会new一次，后续都是用同一个实例对象
        SpringMQProduce produce = ctx.getBean(SpringMQProduce.class);

        // 由于 目标队列 在配置文件指定了，所以在发送的时候不需要再指定
         produce.jmsTemplate.send((session -> {
             TextMessage textMessage = session.createTextMessage("Spring和Active整合的消息");
             return textMessage;
         }));

        System.out.println("消息发送完毕");

    }

}
