一、ActiveMQ结合Spring使用

pom文件：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">    <modelVersion>4.0.0</modelVersion>    <groupId>com.activemq</groupId>    <artifactId>jmsTest</artifactId>    <version>1.0-SNAPSHOT</version>    <packaging>jar</packaging>    <name>jmsTest</name>    <url>http://maven.apache.org</url>    <properties>        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>        <junit.version>4.12</junit.version>        <spring.version>4.2.4.RELEASE</spring.version>        <activemq-all>5.15.0</activemq-all>        <xbean-spring>4.5</xbean-spring>        <activemq-pool>5.15.0</activemq-pool>    </properties>    <dependencies>        <dependency>            <groupId>junit</groupId>            <artifactId>junit</artifactId>            <version>${junit.version}</version>            <scope>test</scope>        </dependency>        <dependency>            <groupId>org.apache.activemq</groupId>            <artifactId>activemq-all</artifactId>            <version>${activemq-all}</version>        </dependency>        <dependency>            <groupId>org.apache.xbean</groupId>            <artifactId>xbean-spring</artifactId>            <version>${xbean-spring}</version>        </dependency>        <!-- Spring -->        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-context</artifactId>            <version>${spring.version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-beans</artifactId>            <version>${spring.version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-webmvc</artifactId>            <version>${spring.version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-jdbc</artifactId>            <version>${spring.version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-aspects</artifactId>            <version>${spring.version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-context-support</artifactId>            <version>${spring.version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-jms</artifactId>            <version>${spring.version}</version>        </dependency>        <dependency>            <groupId>org.apache.activemq</groupId>            <artifactId>activemq-pool</artifactId>            <version>${activemq-pool}</version>        </dependency>    </dependencies></project>

Spring配置文件：applicationContext.xml

<?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.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsdhttp://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.xsdhttp://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-4.2.xsd"><!--配置扫描的包--><context:component-scan base-package="com.activemq.spring"/><!--使用CGLib动态代理技术织入增强--><aop:aspectj-autoproxy proxy-target-class="true"/><!--配置连接工厂--><bean id="jmsFactory" class="org.apache.activemq.jms.pool.PooledConnectionFactory" destroy-method="stop"><property name="connectionFactory"><bean class="org.apache.activemq.ActiveMQConnectionFactory"><property name="brokerURL"><value>tcp://192.168.1.100:61616</value></property><property name="userName" value="admin"/><property name="password" value="admin"/></bean></property><property name="maxConnections" value="100"/></bean><!--配置destination--><bean id="destination" class="org.apache.activemq.command.ActiveMQQueue"><constructor-arg index="0" value="spring-queue"/></bean><!--配置jmsTemplate--><bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate"><property name="connectionFactory" ref="jmsFactory"/><property name="defaultDestination" ref="destination"/><property name="messageConverter"><bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/></property></bean></beans>

发送端代码：com.activemq.spring.SpringQueueSender.java

package com.activemq.spring;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;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;/** * @version 1.0 * @description: * @author: taozhiyaoyao * @date 2017/9/6 */@Servicepublic class SpringQueueSender {    @Autowired    private JmsTemplate jmsTemplate;    public static void main(String[] args) throws  Exception {        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");        SpringQueueSender sqs = (SpringQueueSender) applicationContext.getBean("springQueueSender");        sqs.jmsTemplate.send(new MessageCreator() {            @Override            public Message createMessage(Session session) throws JMSException {                TextMessage textMessage = session.createTextMessage("Spring Message");                return textMessage;            }        });    }}

接收端代码：com.activemq.spring.SpringQueueReceiver.java

package com.activemq.spring;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.springframework.jms.core.JmsTemplate;import org.springframework.stereotype.Service;/** * @version 1.0 * @description: * @author: taozhiyaoyao * @date 2017/9/6 */@Servicepublic class SpringQueueReceiver {    @Autowired    private JmsTemplate jmsTemplate;    public static void main(String[] args) throws  Exception {        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");        SpringQueueReceiver sqr = (SpringQueueReceiver) applicationContext.getBean("springQueueReceiver");        String message = (String)sqr.jmsTemplate.receiveAndConvert();        System.out.print("The Message is " + message);    }}

OK，这个Queue类型的发送实例，如果是Topic的话：需要修改一下Spring的配置文件，

<bean id="destinationTopic" class="org.apache.activemq.command.ActiveMQTopic"><constructor-arg index="0" value="spring-topic"/></bean><!--配置jmsTemplate--><bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate"><property name="connectionFactory" ref="jmsFactory"/><!--<property name="defaultDestination" ref="destination"/>--><property name="defaultDestination" ref="destinationTopic"/><property name="messageConverter"><bean class="org.springframework.jms.support.converter.SimpleMessageConverter"/></property></bean>package com.activemq.spring;import javax.jms.JMSException;import javax.jms.Message;import javax.jms.MessageListener;import javax.jms.TextMessage;/** * @version 1.0 * @description: * @author: taozhiyaoyao * @date 2017/9/6 */public class MyMessageListener implements MessageListener {    @Override    public void onMessage(Message message) {        TextMessage textMessage = (TextMessage) message;        try {            System.out.println("receive text message : " + textMessage.getText());        } catch (JMSException e) {            e.printStackTrace();        }    }}



<!--配置消费者--><bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer"><property name="connectionFactory" ref="jmsFactory"/><property name="destination" ref="destinationTopic"/><property name="messageListener" ref="messageListener"/></bean><bean id="messageListener" class="com.activemq.spring.MyMessageListener"/>
MyMessageListener.java
package com.activemq.spring;import javax.jms.JMSException;import javax.jms.Message;import javax.jms.MessageListener;import javax.jms.TextMessage;/** * @version 1.0 * @description: * @author: taozhiyaoyao * @date 2017/9/6 */public class MyMessageListener implements MessageListener {    @Override    public void onMessage(Message message) {        TextMessage textMessage = (TextMessage) message;        try {            System.out.println("receive text message : " + textMessage.getText());        } catch (JMSException e) {            e.printStackTrace();        }    }}

这样的话即使接收端不启动，也会收到消息。
