ActiveMQ—整合Spring

阅读完需：约 4 分钟

ActiveMQ 原始的使用方法：

1. 使用方法

第一步：引用相关的jar包。

<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-jms</artifactId>
</dependency>
<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-context-support</artifactId>
</dependency>
 <dependency>
	<groupId>org.apache.activemq</groupId>
	<artifactId>activemq-all</artifactId>
	<version>5.11.2</version>
</dependency>

第二步：配置Activemq整合spring。配置ConnectionFactory,生产者,Destination

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	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
	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd
	http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd
	http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd">
	
	<!-- 真正可以产生Connection的ConnectionFactory，由对应的 JMS服务厂商提供 -->
	<bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
		<property name="brokerURL" value="tcp://115.159.126.205:61616" />
	</bean>
	<!-- Spring用于管理真正的ConnectionFactory的ConnectionFactory -->
	<bean id="connectionFactory"
		class="org.springframework.jms.connection.SingleConnectionFactory">
		<!-- 目标ConnectionFactory对应真实的可以产生JMS Connection的ConnectionFactory -->
		<property name="targetConnectionFactory" ref="targetConnectionFactory" />
	</bean>
	<!-- 配置生产者 -->
	<!-- Spring提供的JMS工具类，它可以进行消息发送、接收等 -->
	<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
		<!-- 这个connectionFactory对应的是我们定义的Spring提供的那个ConnectionFactory对象 -->
		<property name="connectionFactory" ref="connectionFactory" />
	</bean>
	<!--这个是队列目的地，点对点的 -->
	<bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
		<constructor-arg>
			<value>spring-queue</value>
		</constructor-arg>
	</bean>
	<!--这个是主题目的地，一对多的 -->
	<bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">
		<constructor-arg value="itemAddTopic" />
	</bean>
</beans>

第三步：代码测试

package cn.e3mall.activemq;
 
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;
 
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
 
/**
 * sping 整合activeMQ
 * @author cxx
 *
 */
public class ActiveMqSpringTest {
	@Test
	public void sendMessage() throws Exception {
		//初始化spring容器
		ApplicationContext applicationContext = new ClassPathXmlApplicationContext("classpath:spring/applicationContext-activemq.xml");
		//从容器中获得JmsTemplate对象。
		JmsTemplate jmsTemplate = applicationContext.getBean(JmsTemplate.class);
		//从容器中获得一个Destination对象。
		Destination destination = (Destination) applicationContext.getBean("queueDestination");
		//发送消息
		jmsTemplate.send(destination, new MessageCreator() {
			@Override
			public Message createMessage(Session session) throws JMSException {
				return session.createTextMessage("send activemq message");
			}
		});
	}
}

2.接收消息

e3-search-Service中接收消息。

第一步：把Activemq相关的jar包添加到工程中

第二步：创建一个MessageListener的实现类。

package cn.e3mall.activemq;
 
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
 
public class MessageConsumer {
 
	@Test
	public void msgConsumer() throws Exception {
		//初始化spring容器
		ApplicationContext applicationContext =  new ClassPathXmlApplicationContext("classpath:spring/applicationContext-activemq.xml");
		//等待
		System.in.read();
	}
}

配置spring和Activemq整合

	http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd">
	
	<!-- 真正可以产生Connection的ConnectionFactory，由对应的 JMS服务厂商提供 -->
	<bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
		<property name="brokerURL" value="tcp://115.159.126.205:61616" />
	</bean>
	<!-- Spring用于管理真正的ConnectionFactory的ConnectionFactory -->
	<bean id="connectionFactory"
		class="org.springframework.jms.connection.SingleConnectionFactory">
		<!-- 目标ConnectionFactory对应真实的可以产生JMS Connection的ConnectionFactory -->
		<property name="targetConnectionFactory" ref="targetConnectionFactory" />
	</bean>
	<!--这个是队列目的地，点对点的 -->
	<bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">
		<constructor-arg>
			<value>spring-queue</value>
		</constructor-arg>
	</bean>
	<!--这个是主题目的地，一对多的 -->
	<bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">
		<constructor-arg value="itemAddTopic" />
	</bean>
	<!-- 配置bean -->
	<bean id="myMessageListener" class="cn.e3mall.search.message.MyMessageListener"/>
	<!-- 消息监听容器 -->
	<bean class="org.springframework.jms.listener.DefaultMessageListenerContainer">
		<property name="connectionFactory" ref="connectionFactory" />
		<property name="destination" ref="queueDestination" />
		<property name="messageListener" ref="myMessageListener" />
	</bean>
</beans>

测试代码

package cn.e3mall.activemq;
 
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
 
public class MessageConsumer {
 
	@Test
	public void msgConsumer() throws Exception {
		//初始化spring容器
		ApplicationContext applicationContext =  new ClassPathXmlApplicationContext("classpath:spring/applicationContext-activemq.xml");
		//等待
		System.in.read();
	}
}
