ActiveMQ 的的使用

消息队列

消息生产者：JMSProducer

package com.me.activemq;import javax.jms.Connection;import javax.jms.ConnectionFactory;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;/** * 消息生产者 * @author Administrator * */public class JMSProducer {private static final String USERNAME = ActiveMQConnection.DEFAULT_USER;// 默认的连接的用户名private static final String PASSWORD = ActiveMQConnection.DEFAULT_PASSWORD;// 默认的连接的密码private static final String BROKER_URL = ActiveMQConnection.DEFAULT_BROKER_URL;// 默认的连接地址private static final int SENDNUM = 10;// 发送的消息数量public static void main(String[] args) {ConnectionFactory connectionFactory;// 连接工厂Connection connection = null;// 连接Session session;// 回话 接受或者发送消息的线程Destination destination;// 消息的目的地MessageProducer messageProducer;// 消息的消费者// 实例化连接工厂connectionFactory = new ActiveMQConnectionFactory(JMSProducer.USERNAME, JMSProducer.PASSWORD,JMSProducer.BROKER_URL);try {connection = connectionFactory.createConnection();// 通过工厂获取连接connection.start();// 启动连接session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);// 创建sessiondestination = session.createQueue("FirstQueue1");// 创建消息队列messageProducer = session.createProducer(destination);// 创建消息的生产者sendMessage(session, messageProducer);//发送消息session.commit();} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();} finally {if(connection!=null){try {connection.close();} catch (JMSException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}}public static void sendMessage(Session session,MessageProducer messageProducer) throws JMSException{for (int i = 0; i < JMSProducer.SENDNUM; i++) {TextMessage message =session.createTextMessage("ActiveMQ 发送的消息"+i);System.out.println("ActiveMQ 发送的消息"+i);messageProducer.send(message);}}}<span style="font-family:Arial, Helvetica, sans-serif;"><span style="white-space: normal;"></span></span>

消息消费者第一种方式（不推荐）

package com.me.activemq;import javax.jms.Connection;import javax.jms.ConnectionFactory;import javax.jms.Destination;import javax.jms.MessageConsumer;import javax.jms.Session;import javax.jms.TextMessage;import org.apache.activemq.ActiveMQConnection;import org.apache.activemq.ActiveMQConnectionFactory;/** * 消息消费者 *  * @author Administrator * */public class JMSConsumer {private static final String USERNAME = ActiveMQConnection.DEFAULT_USER;// 默认的连接的用户名private static final String PASSWORD = ActiveMQConnection.DEFAULT_PASSWORD;// 默认的连接的密码private static final String BROKER_URL = ActiveMQConnection.DEFAULT_BROKER_URL;// 默认的连接地址public static void main(String[] args) {ConnectionFactory connectionFactory;// 连接工厂Connection connection = null;// 连接Session session;// 回话 接受或者发送消息的线程Destination destination;// 消息的目的地MessageConsumer messageConsumer;// 消息的消费者// 实例化连接工厂connectionFactory = new ActiveMQConnectionFactory(JMSConsumer.USERNAME, JMSConsumer.PASSWORD,JMSConsumer.BROKER_URL);try {connection = connectionFactory.createConnection();// 通过工厂获取连接connection.start();// 启动连接session = connection.createSession(Boolean.FALSE, Session.AUTO_ACKNOWLEDGE);// 创建sessiondestination = session.createQueue("FirstQueue1");// 创建连接的消息队列messageConsumer = session.createConsumer(destination);// 创建消费者while (true) {TextMessage textMessage = (TextMessage) messageConsumer.receive(100000);if (textMessage != null) {System.out.println("收到的消息：" + textMessage.getText());} else {break;}}} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();} //}}

消息消费者第二种方式（使用监听）

消息监听器：

package com.me.activemq;import javax.jms.JMSException;import javax.jms.Message;import javax.jms.MessageListener;import javax.jms.TextMessage;/** * 消息监听 *  * @author Administrator * */public class Listener implements MessageListener {@Overridepublic void onMessage(Message message) {try {System.out.println("收到的消息：" + ((TextMessage) message).getText());} catch (JMSException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}

JMSConsumer2

package com.me.activemq;import javax.jms.Connection;import javax.jms.ConnectionFactory;import javax.jms.Destination;import javax.jms.MessageConsumer;import javax.jms.Session;import javax.jms.TextMessage;import org.apache.activemq.ActiveMQConnection;import org.apache.activemq.ActiveMQConnectionFactory;/** * 消息消费者 *  * @author Administrator * */public class JMSConsumer2 {private static final String USERNAME = ActiveMQConnection.DEFAULT_USER;// 默认的连接的用户名private static final String PASSWORD = ActiveMQConnection.DEFAULT_PASSWORD;// 默认的连接的密码private static final String BROKER_URL = ActiveMQConnection.DEFAULT_BROKER_URL;// 默认的连接地址public static void main(String[] args) {ConnectionFactory connectionFactory;// 连接工厂Connection connection = null;// 连接Session session;// 回话 接受或者发送消息的线程Destination destination;// 消息的目的地MessageConsumer messageConsumer;// 消息的消费者// 实例化连接工厂connectionFactory = new ActiveMQConnectionFactory(JMSConsumer2.USERNAME, JMSConsumer2.PASSWORD,JMSConsumer2.BROKER_URL);try {connection = connectionFactory.createConnection();// 通过工厂获取连接connection.start();// 启动连接session = connection.createSession(Boolean.FALSE, Session.AUTO_ACKNOWLEDGE);// 创建sessiondestination = session.createQueue("FirstQueue1");// 创建连接的消息队列messageConsumer = session.createConsumer(destination);// 创建消费者    messageConsumer.setMessageListener(new Listener());//注册消息监听} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();} //}}

订阅/发布

消息生产者-消息发布者：

package com.me.activemq2;import javax.jms.Connection;import javax.jms.ConnectionFactory;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;/** * 消息生产者-消息发布者 * @author Administrator * */public class JMSProducer {private static final String USERNAME = ActiveMQConnection.DEFAULT_USER;// 默认的连接的用户名private static final String PASSWORD = ActiveMQConnection.DEFAULT_PASSWORD;// 默认的连接的密码private static final String BROKER_URL = ActiveMQConnection.DEFAULT_BROKER_URL;// 默认的连接地址private static final int SENDNUM = 10;// 发送的消息数量public static void main(String[] args) {ConnectionFactory connectionFactory;// 连接工厂Connection connection = null;// 连接Session session;// 回话 接受或者发送消息的线程Destination destination;// 消息的目的地MessageProducer messageProducer;// 消息的消费者// 实例化连接工厂connectionFactory = new ActiveMQConnectionFactory(JMSProducer.USERNAME, JMSProducer.PASSWORD,JMSProducer.BROKER_URL);try {connection = connectionFactory.createConnection();// 通过工厂获取连接connection.start();// 启动连接session = connection.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);// 创建session//destination = session.createQueue("FirstQueue1");// 创建消息队列destination=session.createTopic("FirstTopic1");messageProducer = session.createProducer(destination);// 创建消息的生产者sendMessage(session, messageProducer);//发送消息session.commit();} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();} finally {if(connection!=null){try {connection.close();} catch (JMSException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}}public static void sendMessage(Session session,MessageProducer messageProducer) throws JMSException{for (int i = 0; i < JMSProducer.SENDNUM; i++) {TextMessage message =session.createTextMessage("ActiveMQ 发送的消息"+i);System.out.println("ActiveMQ 发送的消息"+i);messageProducer.send(message);}}}

消息订阅者一

监听器

package com.me.activemq2;import javax.jms.JMSException;import javax.jms.Message;import javax.jms.MessageListener;import javax.jms.TextMessage;/** * 消息监听 *  * @author Administrator * */public class Listener implements MessageListener {@Overridepublic void onMessage(Message message) {try {System.out.println("订阅者一收到的消息：" + ((TextMessage) message).getText());} catch (JMSException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}

消息消费者--消息订阅者1

package com.me.activemq2;import javax.jms.Connection;import javax.jms.ConnectionFactory;import javax.jms.Destination;import javax.jms.MessageConsumer;import javax.jms.Session;import org.apache.activemq.ActiveMQConnection;import org.apache.activemq.ActiveMQConnectionFactory;/** * 消息消费者--消息订阅者1 *  * @author Administrator * */public class JMSConsumer {private static final String USERNAME = ActiveMQConnection.DEFAULT_USER;// 默认的连接的用户名private static final String PASSWORD = ActiveMQConnection.DEFAULT_PASSWORD;// 默认的连接的密码private static final String BROKER_URL = ActiveMQConnection.DEFAULT_BROKER_URL;// 默认的连接地址public static void main(String[] args) {ConnectionFactory connectionFactory;// 连接工厂Connection connection = null;// 连接Session session;// 回话 接受或者发送消息的线程Destination destination;// 消息的目的地MessageConsumer messageConsumer;// 消息的消费者// 实例化连接工厂connectionFactory = new ActiveMQConnectionFactory(JMSConsumer.USERNAME, JMSConsumer.PASSWORD,JMSConsumer.BROKER_URL);try {connection = connectionFactory.createConnection();// 通过工厂获取连接connection.start();// 启动连接session = connection.createSession(Boolean.FALSE, Session.AUTO_ACKNOWLEDGE);// 创建session//destination = session.createQueue("FirstQueue1");// 创建连接的消息队列destination = session.createTopic("FirstTopic1");messageConsumer = session.createConsumer(destination);// 创建消费者messageConsumer.setMessageListener(new Listener());// 注册消息监听} catch (Exception e) {// TODO Auto-generated catch blocke.printStackTrace();} //}}
