ActiveMq技术手册

                                 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

org.apache.activemq                      activemq-all                      5.11.2

 

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

org.apache.activemq                      activemq-all                      5.11.2

 

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

org.springframework                      spring-jms                      4.0.0.RELEASE                                                  org.apache.activemq                      activemq-all                      5.11.2                                                  org.springframework                      spring-context-support                      4.0.0.RELEASE

 

在spring容器中创建MQ工厂

class="org.springframework.jms.connection.SingleConnectionFactory">

 

 

 

MQ执行模板

 

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
