                                 ActiveMq技术手册

 
 

1 介绍

Mq：消息中间件

activeMq：Apache

rabbitmq：AMQP，即Advanced Message Queuing Protocol

kafka：Apache Kafka，大数据

ZeroMQ：简单快速，是个类似于Socket的一系列接口

MetaMQ(RocketMQ)：阿里开源消息中间件MetaQ(RocketMQ)

2 安装

 

Windows和linux通用

1 activeMq start 2 activeMq stop

 

 

Linux安装注意事项

Active集成控制台页面跳转需要配置Hosts文件 1 etc/hosts 配置网络映射地址列表 2 etc/sysconfig/network 配置主机名

 

3 MQ(队列)测试代码

 

Pom依赖信息

<dependency>                      <groupId>org.apache.activemq</groupId>                      <artifactId>activemq-all</artifactId>                      <version>5.11.2</version>               </dependency>

 

发布队列消息到mq

ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);               Connection connection = connectionFactory.createConnection();               connection.start();               Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);               Queue queue = session.createQueue(application);               MessageProducer producer = session.createProducer(queue);                   TextMessage textMessage = session.createTextMessage(message);               producer.send(textMessage);               producer.close();               session.close();               connection.close();

 

消费消息端服务：

 

ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);               Connection connection = connectionFactory.createConnection();               connection.start();               Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);               Queue queue = session.createQueue(application);               MessageConsumer consumer = session.createConsumer(queue);               // 接收消息               consumer.setMessageListener(new MessageListener() {                      @Override                      public void onMessage(Message message) {                             // 打印结果                             TextMessage textMessage = (TextMessage) message;                             String text= textMessage.getText();                             System.out.println(text);                      }               });               // 等待接收消息               System.in.read();

 

4 MQ(订阅模式)测试代码

Pom依赖信息

<dependency>                      <groupId>org.apache.activemq</groupId>                      <artifactId>activemq-all</artifactId>                      <version>5.11.2</version>               </dependency>

 

发布事件消息到mq

ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);               Connection connection = connectionFactory.createConnection();               connection.start();               Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);               Topic topic = session.createTopic(application);               MessageProducer producer = session.createProducer(topic);               TextMessage textMessage = session.createTextMessage(message);               producer.send(textMessage);               producer.close();               session.close();               connection.close();

 

消费消息端服务：

ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);               Connection connection = connectionFactory.createConnection();               connection.start();               Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);               Topic topic = session.createTopic(application);               MessageConsumer consumer = session.createConsumer(topic);               // 接收消息               consumer.setMessageListener(new MessageListener() {                      @Override                      public void onMessage(Message message) {                             // 打印结果                             TextMessage textMessage = (TextMessage) message;                             String text = textMessage.getText();                             System.out.println(text);                      }               });               System.out.println("订阅消费者n。。。。");               // 等待接收消息               System.in.read();        }

5spring整合mq发布任务消息

Pom

<dependency>                      <groupId>org.springframework</groupId>                      <artifactId>spring-jms</artifactId>                      <version>4.0.0.RELEASE</version>               </dependency>               <dependency>                      <groupId>org.apache.activemq</groupId>                      <artifactId>activemq-all</artifactId>                      <version>5.11.2</version>               </dependency>               <dependency>                      <groupId>org.springframework</groupId>                      <artifactId>spring-context-support</artifactId>                      <version>4.0.0.RELEASE</version>               </dependency>

 

在spring容器中创建MQ工厂

<!-- jsm消息工厂 --> <bean id="targetConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">               <property name="brokerURL" value="tcp://localhost:61616" />        </bean>        <bean id="connectionFactory"               class="org.springframework.jms.connection.SingleConnectionFactory">               <!--产生JMS Connection的ConnectionFactory -->               <property name="targetConnectionFactory" ref="targetConnectionFactory" />        </bean>

 

 

 

MQ执行模板

<!-- 执行消息任务的模板 --> <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">               <property name="connectionFactory" ref="connectionFactory" />        </bean>        <bean id="queueDestination" class="org.apache.activemq.command.ActiveMQQueue">               <constructor-arg value="queue" />        </bean>        <bean id="topicDestination" class="org.apache.activemq.command.ActiveMQTopic">               <constructor-arg value="topic" />        </bean>

 

消息产生端测试代码：即消息任务发布的系统程序

// 发送mq消息               jmsTemplate.send(destination, new MessageCreator() {                      @Override                      public Message createMessage(Session session) throws JMSException {                             return session.createTextMessage("send activemq message");                      }               });

6 spring整合mq执行消息任务

通过实现MessageListener创建监听类，获得消息任务信息

MyMessageListener

import javax.jms.MessageListener public class MyMessageListener implements MessageListener {        @Override        public void onMessage(Message message) {               // 消息内容               TextMessage textMessage = (TextMessage) message;               String text = textMessage.getText();               System.out.println(text);        } }

 

 

配置监听到spring容器中

<bean id="myMessageListener" class="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>        <!--订阅模式监听容器-->        <bean class="org.springframework.jms.listener.DefaultMessageListenerContainer">               <property name="connectionFactory" ref="connectionFactory" />               <property name="destination" ref="topicDestination" />               <property name="messageListener" ref="myMessageListener" />        </bean>
