ActiveMQ集成Spring使用

　　现在任何一个框架的使用都会结合spring框架，quartz、cxf与平时常见的Hibernate、mybatis、Struts等都可以与spring集成起来使用，在这里研究了activemq结合spring的使用方法。

1.理论篇

　　spring集成JMS连接ActiveMq

　　　　ConnectionFactory：用于管理连接的工厂(Spring为我们提供的连接池，因为JmsTemplate每次发消息都会重新创建连接、会话和producer，这个操作非常消耗性能，所以Spring提供了连接池)

　　　　　　spring提供了两个实现类:SingleConnectionFactory--整个应用使用同一个Connection进行操作，并且重写了其close()方法

　　　　　　　　　　　　　　　　  CachingConnectionFactory--继承自SingleConnectionFactory，所以有SingleConnectionFactory的所有功能，并且额外提供了缓存功能，可以缓存Session、producer、consumer等。

　　　　JmsTemplate:用于接收和发送消息的模板。Spring提供的，我们只需要向spring容器注册这个类就可以使用JmsTemplate方便的操作JMS。JmsTemplate类是线程安全的，可以在整个范围内使用，而且我们可以注册多个JmsTemplate到spring中。

　　　　MessageListener:消息监听器。需要我们手动实现，只需要实现一个omMessage(Message message)方法。

 

2.代码实现spring集成activemq

0.pom.xml配置与目录结构与log4j.properties

 

log4j.rootLogger=info,B,A

log4j.appender.A=org.apache.log4j.ConsoleAppender
log4j.appender.A.layout=org.apache.log4j.PatternLayout
log4j.appender.A.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%c]-[%p] %m%n

log4j.appender.B=org.apache.log4j.RollingFileAppender
log4j.appender.B.File=E:\\jms.log
log4j.appender.B.MaxFileSize=10MB
log4j.appender.B.MaxBackupIndex=5
log4j.appender.B.layout=org.apache.log4j.PatternLayout
log4j.appender.B.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%c]-[%p] %m%n

 1.队列模式的MQ实现(Destination设置为ActiveMQQueue即可)

ApplicationContext-all.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 http://www.springframework.org/schema/context/spring-context.xsd">
    <!--配置扫描注解的包-->
    <context:component-scan base-package="cn.qlq.jms" ></context:component-scan>

    <!--Spring为我们提供的ConnectionFactory-->
    <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://localhost:61616"></property>
    </bean>

    <!--Spring jms为我们提供的连接池-->
    <bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
        <property name="targetConnectionFactory" ref="targetConnectionFactory"/>
    </bean>

    <!--一个队列的目的地，构造方法指定queueName，点对点模式-->
    <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
        <constructor-arg value="queue"></constructor-arg>
    </bean>

    <!--spring JMS提供的JmsTemplate-->
    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory" ref="connectionFactory"/>
    </bean>


    <!--消费消息容器(需要注入连接工厂，目的地，消息消费者监听器)-->
    <bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="connectionFactory"/>
        <property name="destination" ref="queueDestination"/>
        <property name="messageListener" ref="myConsumer"/>
    </bean>
</beans>

 

 生产者接口和实现类:

package cn.qlq.jms.producer;

/**
 * @Author: qlq
 * @Description
 * @Date: 21:25 2018/9/27
 */
public interface MyProducer {
    void sendMessage(String message);
}

 

package cn.qlq.jms.producer;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.stereotype.Service;

import javax.jms.*;

/**
 * @Author: qlq
 * @Description
 * @Date: 21:26 2018/9/27
 */

@Service
public class MyProducerImpl implements MyProducer {
    private static final Logger logger = LoggerFactory.getLogger(MyProducerImpl.class);
    @Autowired
    private JmsTemplate jmsTemplate;
    @Autowired
    @Qualifier("queueDestination")
    private Destination destination;

    public void sendMessage(final String message) {
        jmsTemplate.send(destination, new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                TextMessage textMessage = session.createTextMessage(message);
                return textMessage;
            }
        });
        logger.info("send textMesage:{}",message);
    }
}

 

消费消息监听器代码:

package cn.qlq.jms.producer;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Service;

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

/**
 * @Author: qlq
 * @Description
 * @Date: 22:36 2018/9/27
 */
@Service
public class MyConsumer implements MessageListener {
    private static final Logger logger = LoggerFactory.getLogger(MyConsumer.class);

    public void onMessage(Message message) {
        TextMessage textMessage = (TextMessage) message;
        try {
            System.out.println("consumer message:"+ textMessage.getText());
        } catch (JMSException e) {
            logger.error("consume message error", e);
        }
    }
}

 

生产者启动类:启动spring容器，获取bean并且发布消息:

package cn.qlq.jms.producer;

import org.apache.xbean.spring.context.ClassPathXmlApplicationContext;
import org.springframework.context.ApplicationContext;

/**
 * @Author: qlq
 * @Description 生产消息的入口类
 * @Date: 22:15 2018/9/27
 */
public class ProducerApp {
    public static void main(String[] args) {
        ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("ApplicationContext-all.xml");
//        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("ApplicationContext-all.xml");
        MyProducer myProducer = (MyProducer) applicationContext.getBean("myProducerImpl");
        for (int i = 0; i < 100; i++) {
            myProducer.sendMessage(" message"+i);
        }
        applicationContext.close();//关闭容器，会自动关闭所有的资源
    }
}

 

消费者启动类:启动spring容器，会自动监听目的地的消息:

package cn.qlq.jms.producer;

import org.apache.xbean.spring.context.ClassPathXmlApplicationContext;

/**
 * @Author: qlq
 * @Description 消费消息的入口类
 * @Date: 22:15 2018/9/27
 */
public class ConsumerApp {
    public static void main(String[] args) {
        //启动容器会自动消费消息
        ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("ApplicationContext-all.xml");
    }
}

 

 启动三个消费者一个生产者，查看控制台结果:(符合队列模式的特点:平均消费)

 

 

 

 

 

activemq后台查看结果:(已经停掉3个消费者线程所以消费者是0)

 

 2.主题模式的MQ实现(Destination设置为ActiveMQQueue即可)

 在Spring的xml配置文件中增加topic目的地，并且将消息监听的目的地设为topicDestination

<?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 http://www.springframework.org/schema/context/spring-context.xsd">
    <!--配置扫描注解的包-->
    <context:component-scan base-package="cn.qlq.jms" ></context:component-scan>

    <!--Spring为我们提供的ConnectionFactory-->
    <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
        <property name="brokerURL" value="tcp://localhost:61616"></property>
    </bean>

    <!--Spring jms为我们提供的连接池-->
    <bean id="connectionFactory" class="org.springframework.jms.connection.SingleConnectionFactory">
        <property name="targetConnectionFactory" ref="targetConnectionFactory"/>
    </bean>

    <!--一个队列的目的地，构造方法指定queueName，点对点模式-->
    <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
        <constructor-arg value="queue"></constructor-arg>
    </bean>

    <!--spring JMS提供的JmsTemplate-->
    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory" ref="connectionFactory"/>
    </bean>


    <!--消费消息容器(需要注入连接工厂，目的地，消息消费者监听器)-->
    <bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
        <property name="connectionFactory" ref="connectionFactory"/>
        <property name="destination" ref="topicDestination"/>
        <property name="messageListener" ref="myConsumer"/>
    </bean>

    <!--一个队列的目的地，构造方法指定queueName，点对点模式-->
    <bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">
        <constructor-arg value="topic"></constructor-arg>
    </bean>
</beans>

 

 消息生产者将目的地注入为topicDestination

package cn.qlq.jms.producer;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.stereotype.Service;

import javax.jms.*;

/**
 * @Author: qlq
 * @Description
 * @Date: 21:26 2018/9/27
 */

@Service
public class MyProducerImpl implements MyProducer {
    private static final Logger logger = LoggerFactory.getLogger(MyProducerImpl.class);
    @Autowired
    private JmsTemplate jmsTemplate;
    @Autowired
    @Qualifier("topicDestination")
    private Destination destination;

    public void sendMessage(final String message) {
        jmsTemplate.send(destination, new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                TextMessage textMessage = session.createTextMessage(message);
                return textMessage;
            }
        });
        logger.info("send textMesage:{}",message);
    }
}

 

 　　剩下的测试代码同上，还是先开启三个消费者，再开启一个生产者，查看结果:(符合订阅模式特点:消费所有已经订阅的消息)

 

 

 

 

activemq后台查看结果:
