ActiveMQ 样例

1.使用JAVA程序直接访问ActiveMQ

1.1 发送消息

package com.activemq;import java.util.Date;import javax.jms.Connection;import javax.jms.ConnectionFactory;import javax.jms.DeliveryMode;import javax.jms.Destination;import javax.jms.JMSException;import javax.jms.MessageProducer;import javax.jms.Session;import javax.jms.TextMessage;import org.apache.activemq.ActiveMQConnection;import org.apache.activemq.ActiveMQConnectionFactory;import org.slf4j.Logger;import org.slf4j.LoggerFactory;/** * ActiveMQ 发送消息 * @author brushli * @date 2014-12-05 */public class Sender {private static final Logger logger = LoggerFactory.getLogger(Sender.class);    public void sendMessage(){    try {    ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(ActiveMQConnection.DEFAULT_USER, ActiveMQConnection.DEFAULT_PASSWORD, "failover://tcp://127.0.0.1:61616");    Connection connection = connectionFactory.createConnection();connection.start();//（parameter a:是否支持事务，parameter b:消息应答模式）Session session = connection.createSession(Boolean.FALSE, Session.AUTO_ACKNOWLEDGE);Destination destination = session.createQueue("myQueue");//创建什么什么模式的生产者，可选参数： Queue, TemporaryQueue, TemporaryTopic, TopicMessageProducer producer = session.createProducer(destination);producer.setDeliveryMode(DeliveryMode.PERSISTENT);logger.info("begin to send Message! currentTime="+new Date().toLocaleString());for(int i=1; i<=10; i++) {  TextMessage message = session.createTextMessage();  message.setText("Hello World!" + new Date().toLocaleString());producer.send(message); }  logger.info("send Message finished! currentTime="+new Date().toLocaleString());session.close();  connection.close();  } catch (JMSException e) {e.printStackTrace();}     }    public static void main(String[] args) {Sender sender = new Sender();sender.sendMessage();}}

1.2 接收消息

package com.activemq;import java.util.Date;import javax.jms.Connection;import javax.jms.ConnectionFactory;import javax.jms.Destination;import javax.jms.JMSException;import javax.jms.MessageConsumer;import javax.jms.Session;import javax.jms.TextMessage;import org.apache.activemq.ActiveMQConnection;import org.apache.activemq.ActiveMQConnectionFactory;import org.slf4j.Logger;import org.slf4j.LoggerFactory;/** * ActiveMQ 接收消息 * @author brushli * @date 2014-12-05 */public class Receiver {private static final Logger logger = LoggerFactory.getLogger(Sender.class);public void receiveMessage(){Connection connection = null;Session session = null;try {    ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(ActiveMQConnection.DEFAULT_USER, ActiveMQConnection.DEFAULT_PASSWORD, "failover://tcp://127.0.0.1:61616");    connection = connectionFactory.createConnection();  connection.start();//（parameter a:是否支持事务，parameter b:消息应答模式）session = connection.createSession(Boolean.FALSE, Session.AUTO_ACKNOWLEDGE);Destination destination = session.createQueue("myQueue");MessageConsumer consumer = session.createConsumer(destination);logger.info("begin to receive Message! currentTime="+new Date().toLocaleString());while (true) {                //设置接收者接收消息的时间，为了便于测试，这里谁定为100sTextMessage message = (TextMessage) consumer.receive();                if (null != message) {                    logger.info(message.getText());                }            }} catch (JMSException e) {e.printStackTrace();}finally{try {session.close();  connection.close();} catch (JMSException e) {e.printStackTrace();}  }    }public static void main(String[] args) {Receiver receiver = new Receiver();receiver.receiveMessage();}}

2.Spring集成ActiveMQ

2.1 配置文件activemq.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:p="http://www.springframework.org/schema/p"      xmlns:context="http://www.springframework.org/schema/context"    xmlns:util="http://www.springframework.org/schema/util"      xsi:schemaLocation="http://www.springframework.org/schema/beans           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd               http://www.springframework.org/schema/context                 http://www.springframework.org/schema/context/spring-context-3.0.xsd            http://www.springframework.org/schema/util            http://www.springframework.org/schema/util/spring-util-3.0.xsd ">        <!-- 配置connectionFactory -->      <bean id="mqFactory" class="org.apache.activemq.spring.ActiveMQConnectionFactory">    <property name="brokerURL">          <value>failover:(tcp://127.0.0.1:61616?connectionTimeout=50&soTimeout=100)?jms.prefetchPolicy.queuePrefetch=1&initialReconnectDelay=10&timeout=50</value>      </property>    <property name="sendTimeout" value="1000"></property>    <property name="closeTimeout" value="1000"></property>    <property name="useAsyncSend" value="true"></property></bean>  <bean id="jmsFactory" class="org.springframework.jms.connection.CachingConnectionFactory">      <constructor-arg ref="mqFactory" />      <property name="reconnectOnException" value="true"/>      <property name="sessionCacheSize" value="100" /><!-- 缓存的消息数 --> </bean>    <!-- Spring JMS Template -->      <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">          <property name="connectionFactory">              <ref local="jmsFactory" />           </property>          <property name="deliveryMode" value="2"></property><!-- 消息的传送机制:1 非持久化,2 持久化 -->        <property name="deliveryPersistent" value="true"></property>        <property name="explicitQosEnabled" value="true"></property>        <property name="timeToLive" value="0"></property><!-- 消息的有效期,0表示永不过期 -->    </bean>          <!-- 消息监听     -->      <bean id="listenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">          <property name="concurrentConsumers" value="5" />  <!-- 5个并发消费者 -->        <property name="connectionFactory" ref="jmsFactory" />          <property name="destination" ref="myQueue" />          <property name="messageListener" ref="messageReceiver" />    </bean><!-- 创建队列 -->    <bean id="myQueue" class="org.apache.activemq.command.ActiveMQQueue">        <constructor-arg index="0">            <value>myQueue</value>        </constructor-arg>    </bean><!-- 消息发送者 --><bean id="messageSender" class="com.activemq.MessageSender"><property name="jmsTemplate" ref="jmsTemplate"/></bean><!-- 消息接收者 --><bean id="messageReceiver" class="com.activemq.MessageReceiver"/></beans>

2.2 消息发送

package com.activemq;import java.util.HashMap;import java.util.Map;import javax.jms.Destination;import javax.jms.JMSException;import javax.jms.Message;import javax.jms.Session;import org.apache.activemq.command.ActiveMQQueue;import org.springframework.jms.JmsException;import org.springframework.jms.core.JmsTemplate;import org.springframework.jms.core.MessageCreator;/** * ActiveMQ 发送消息 * @author brushli * @date 2014-12-05 */public class MessageSender {private JmsTemplate jmsTemplate;private Map<String, Destination> destinationMap = new HashMap<String, Destination>();public void setJmsTemplate(JmsTemplate jmsTemplate) {this.jmsTemplate = jmsTemplate;}public void sendMessage(final String message, String destinationName) throws Exception {Destination destination = null;if(!destinationMap.containsKey(destinationName)){destination = new ActiveMQQueue(destinationName);destinationMap.put(destinationName, destination);}destination = destinationMap.get(destinationName);try {jmsTemplate.send(destination, new MessageCreator() {public Message createMessage(Session session) throws JMSException {//return session.createObjectMessage(object);//发送序列化的复杂对象return session.createTextMessage(message); //发送序列化的字符串}});} catch (JmsException e) {e.printStackTrace();}}}

2.3 消息接收

package com.activemq;import javax.jms.JMSException;import javax.jms.Message;import javax.jms.MessageListener;import javax.jms.TextMessage;import org.slf4j.Logger;import org.slf4j.LoggerFactory;/** * ActiveMQ 接收消息 * @author brushli * @date 2014-12-05 */public class MessageReceiver implements MessageListener {    private static final Logger logger = LoggerFactory.getLogger(MessageReceiver.class); @Overridepublic void onMessage(Message message) {if (message instanceof TextMessage) {try {logger.info("receive message: " + ((TextMessage) message).getText());} catch (JMSException e) {e.printStackTrace();}} }}

2.4 启动项目

package com.activemq;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class Test {    private static final Logger logger = LoggerFactory.getLogger(Test.class);public static void main(String[] args) {ApplicationContext context = new ClassPathXmlApplicationContext("./activemq.xml");MessageSender messageSender = (MessageSender)context.getBean("messageSender");try {logger.info("begin to send message");messageSender.sendMessage("test", "myQueue");logger.info("message already send!");} catch (Exception e) {e.printStackTrace();}}}
