04 activemq与spring的整合

本文将阐述如何把activemq与spring集成。

1、前提约束

• 可以使用java完成activemq的topic模式 https://www.jianshu.com/p/d3993d12f3f7

2、修改pom.xml

在pom.xml中加入以下依赖：

        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-all</artifactId>
            <version>5.15.3</version>
        </dependency>
        <dependency>
            <groupId>org.apache.solr</groupId>
            <artifactId>solr-solrj</artifactId>
            <version>4.10.3</version>
        </dependency>
        <dependency>
            <groupId>commons-logging</groupId>
            <artifactId>commons-logging</artifactId>
            <version>1.2</version>
        </dependency>

        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-beans</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aspects</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jms</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
            <version>4.2.4.RELEASE</version>
        </dependency>

3、创建一个消费者的消息监听

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

public class MessageAddListener implements MessageListener {
    public void onMessage(Message message) {
        TextMessage textMessage=(TextMessage)message;
        try {
            System.out.println("接收到消息："+textMessage.getText());
        } catch (JMSException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

4、创建一个消费者的配置文件applicationContext-activemq-consumer.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"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd">
	<!-- JMS服务厂商提供的ConnectionFactory -->
	<bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
		<constructor-arg name="brokerURL" value="tcp://192.168.100.192:61616"/>
	</bean>
	<!--<bean id="itemAddtopic" class="org.apache.activemq.command.ActiveMQTopic">-->
		<!--<constructor-arg name="name" value="item-add-topic"></constructor-arg>-->
	<!--</bean>-->

	<!-- 配置消息的Destination对象 -->
	<bean id="testQueue" class="org.apache.activemq.command.ActiveMQQueue">
		<constructor-arg name="name" value="testQueue"></constructor-arg>
	</bean>

	<!-- 配置消息的接收者 -->
	<bean id="messageAddListener" class="MessageAddListener"/>

	<bean class="org.springframework.jms.listener.DefaultMessageListenerContainer">
		<property name="connectionFactory" ref="connectionFactory"/>
		<property name="destination" ref="testQueue"/>
		<property name="messageListener" ref="messageAddListener"/>
	</bean>
 </beans>

5、创建一个消费者测试类

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class SpringMqQueueConsumer {
    public static void main(String[] args) throws Exception{
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:applicationContext-activemq-consumer.xml");
        System.in.read();
    }
}

启动测试类。

6、创建一个生产者的配置文件applicationContext-activemq-producer.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"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd">
	<!-- JMS服务厂商提供的ConnectionFactory -->
	<bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
		<constructor-arg name="brokerURL" value="tcp://192.168.100.192:61616"/>
	</bean>
	<!--<bean id="itemAddtopic" class="org.apache.activemq.command.ActiveMQTopic">-->
	<!--<constructor-arg name="name" value="itemaddtopic"></constructor-arg>-->
	<!--</bean>-->

	<!-- 配置消息的Destination对象 -->
	<bean id="testQueue" class="org.apache.activemq.command.ActiveMQQueue">
		<constructor-arg name="name" value="testQueue"></constructor-arg>
	</bean>

	<!-- 配置JMSTemplate -->
	<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
		<property name="connectionFactory" ref="connectionFactory"/>
		<property name="defaultDestination" ref="testQueue"></property>
	</bean>

 </beans>

7、创建一个生产者测试类，即发送消息

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;

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

public class SpringMqQueueProducer {
    public static void main(String[] args) {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:applicationContext-activemq-producer.xml");
        JmsTemplate jmsTemplate = (JmsTemplate) applicationContext.getBean("jmsTemplate");
        Destination destination = (Destination) applicationContext.getBean("testQueue");
        jmsTemplate.send(destination,new MessageCreator() {
            public Message createMessage(Session session) throws JMSException {
                Message message = session.createTextMessage("zhangli");
                return message;
            }
        });
    }
}

启动生产者，这时候去查看消费者的命令行，会看到打印出来的消息，即生产者发送了一条消息，消费者收到了这条消息，注意，我们这里是使用activemq的queue模式测试，当然也可以使用activemq的topic模式。
