ActiveMQ的环境搭建及使用

一：环境搭建

首先需要下载ActiveMQ的开发包：

解压之后，目录结构如下所示：

运行bin目录下的activemq.bat命令，启动ActiveMQ服务。

然后：http://127.0.0.1:8161/admin/ 验证服务启动情况，用户名/密码 admin/admin。界面如下：

二：ActiveMQ使用

引入上面解压包中的activemq-all-5.11.1.jar

1. ActiveMQ 点对点消息实现

    1.1   直接receive方式

         消息生产者：

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; // 默认的连接用户名private static final String PASSWORD=ActiveMQConnection.DEFAULT_PASSWORD; // 默认的连接密码private static final String BROKEURL=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; // 会话 接受或者发送消息的线程Destination destination; // 消息的目的地MessageProducer messageProducer; // 消息生产者// 实例化连接工厂connectionFactory=new ActiveMQConnectionFactory(JMSProducer.USERNAME, JMSProducer.PASSWORD, JMSProducer.BROKEURL);try {connection=connectionFactory.createConnection(); // 通过连接工厂获取连接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();}}}}/** * 发送消息 * @param session * @param messageProducer * @throws Exception */public static void sendMessage(Session session,MessageProducer messageProducer)throws Exception{for(int i=0;i<JMSProducer.SENDNUM;i++){TextMessage message=session.createTextMessage("ActiveMQ 发送的消息"+i);System.out.println("发送消息："+"ActiveMQ 发送的消息"+i);messageProducer.send(message);}}}

          消息消费者：

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;/** * 消息消费者 * @author Administrator * */public class JMSConsumer {private static final String USERNAME=ActiveMQConnection.DEFAULT_USER; // 默认的连接用户名private static final String PASSWORD=ActiveMQConnection.DEFAULT_PASSWORD; // 默认的连接密码private static final String BROKEURL=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; // 会话 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.BROKEURL);try {connection=connectionFactory.createConnection();  // 通过连接工厂获取连接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); // 创建消息消费者while(true){TextMessage textMessage=(TextMessage)messageConsumer.receive(100000);if(textMessage!=null){System.out.println("收到的消息："+textMessage.getText());}else{break;}}} catch (JMSException e) {// TODO Auto-generated catch blocke.printStackTrace();} }}

    1.2   使用Listener监听方式

      生产者代码同上.

       监听器类：

    

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) {// TODO Auto-generated method stubtry {System.out.println("收到的消息："+((TextMessage)message).getText());} catch (JMSException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}

      消息消费者中注册监听器：

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;/** * 消息消费者 * @author Administrator * */public class JMSConsumer2 {private static final String USERNAME=ActiveMQConnection.DEFAULT_USER; // 默认的连接用户名private static final String PASSWORD=ActiveMQConnection.DEFAULT_PASSWORD; // 默认的连接密码private static final String BROKEURL=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; // 会话 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.BROKEURL);try {connection=connectionFactory.createConnection();  // 通过连接工厂获取连接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); // 创建消息消费者messageConsumer.setMessageListener(new Listener()); // 注册消息监听} catch (JMSException e) {// TODO Auto-generated catch blocke.printStackTrace();} }}

2. ActiveMQ 发布-订阅消息模式实现

主要是一个生产者发布对应多个消费者订阅。

消息的生产者：

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; // 默认的连接用户名private static final String PASSWORD=ActiveMQConnection.DEFAULT_PASSWORD; // 默认的连接密码private static final String BROKEURL=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; // 会话 接受或者发送消息的线程Destination destination; // 消息的目的地MessageProducer messageProducer; // 消息生产者// 实例化连接工厂connectionFactory=new ActiveMQConnectionFactory(JMSProducer.USERNAME, JMSProducer.PASSWORD, JMSProducer.BROKEURL);try {connection=connectionFactory.createConnection(); // 通过连接工厂获取连接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<span style="background-color: rgb(255, 255, 102);">destination=session.createTopic("FirstTopic1");</span>messageProducer=session.createProducer(destination); // 创建消息生产者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();}}}}/** * 发送消息 * @param session * @param messageProducer * @throws Exception */public static void sendMessage(Session session,MessageProducer messageProducer)throws Exception{for(int i=0;i<JMSProducer.SENDNUM;i++){TextMessage message=session.createTextMessage("ActiveMQ 发送的消息"+i);System.out.println("发送消息："+"ActiveMQ 发布的消息"+i);messageProducer.send(message);}}}

消息的监听器一：

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

消息的监听器二：

import javax.jms.JMSException;import javax.jms.Message;import javax.jms.MessageListener;import javax.jms.TextMessage;/** * 消息监听-订阅者二 * @author Administrator * */public class Listener2 implements MessageListener{@Overridepublic void onMessage(Message message) {// TODO Auto-generated method stubtry {System.out.println("订阅者二收到的消息："+((TextMessage)message).getText());} catch (JMSException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}

消息的订阅者一：

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 org.apache.activemq.ActiveMQConnection;import org.apache.activemq.ActiveMQConnectionFactory;/** * 消息消费者-消息订阅者一 * @author Administrator * */public class JMSConsumer {private static final String USERNAME=ActiveMQConnection.DEFAULT_USER; // 默认的连接用户名private static final String PASSWORD=ActiveMQConnection.DEFAULT_PASSWORD; // 默认的连接密码private static final String BROKEURL=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; // 会话 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.BROKEURL);try {connection=connectionFactory.createConnection();  // 通过连接工厂获取连接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<span style="background-color: rgb(255, 255, 102);">destination=session.createTopic("FirstTopic1");</span>messageConsumer=session.createConsumer(destination); // 创建消息消费者<span style="background-color: rgb(255, 255, 102);">messageConsumer.setMessageListener(new Listener()); // 注册消息监听</span>} catch (JMSException e) {// TODO Auto-generated catch blocke.printStackTrace();} }}

消息的订阅者二：

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 org.apache.activemq.ActiveMQConnection;import org.apache.activemq.ActiveMQConnectionFactory;/** * 消息消费者-消息订阅者二 * @author Administrator * */public class JMSConsumer2 {private static final String USERNAME=ActiveMQConnection.DEFAULT_USER; // 默认的连接用户名private static final String PASSWORD=ActiveMQConnection.DEFAULT_PASSWORD; // 默认的连接密码private static final String BROKEURL=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; // 会话 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.BROKEURL);try {connection=connectionFactory.createConnection();  // 通过连接工厂获取连接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<span style="background-color: rgb(255, 255, 102);">destination=session.createTopic("FirstTopic1");</span>messageConsumer=session.createConsumer(destination); // 创建消息消费者<span style="background-color: rgb(255, 255, 102);">messageConsumer.setMessageListener(new Listener2()); // 注册消息监听</span>} catch (JMSException e) {// TODO Auto-generated catch blocke.printStackTrace();} }}
