1.linux安装activemq
本例使用docker pull的activemq的镜像，并没有安装，
安装完成之后通过8161端口访问，输入用户名密码(admin)，即可访问activemq的管理界面

2.新建一个maven项目
这是一个ssm项目。pom如下

</build></project>1.非整合spring的单机版
1.queue形式
内容提供者
@Test
public void testQueueMqProducter() throws Exception{ //1.创建链接工厂
ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://www.itzmn.com:61616"); //2.创建链接
Connection connection = factory.createConnection(); //3.开启连接
connection.start(); //4.创建一个session对象
/**
* 第一个参数，是否开启事务，如果开启 后面一个参数无意义
* 第二个参数，应答模式
*/
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); //5.创建一个目的地
Queue testQueue = session.createQueue("testQueue"); //6.创建一个内容提供者
MessageProducer producter = session.createProducer(testQueue); //7.发送消息
TextMessage QMessage = new ActiveMQTextMessage();
QMessage.setText("我是队列信息，要减库存了");
producter.send(QMessage); //8.关闭资源
session.close();
connection.close();
}消费者
@Test
public void testQueueMqConsumer() throws Exception{ //1.创建链接工厂
ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://www.itzmn.com:61616"); //2.创建链接
Connection connection = factory.createConnection(); //3.开启连接
connection.start(); //4.创建一个session对象
/**
* 第一个参数，是否开启事务，如果开启 后面一个参数无意义
* 第二个参数，应答模式
*/
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); //5.创建一个目的地
Queue testQueue = session.createQueue("testQueue"); //6.创建一个消费者
MessageConsumer consumer = session.createConsumer(testQueue); //7.发送消息
TextMessage receive = (TextMessage) consumer.receive();
System.out.println(receive.getText()); //8.关闭资源
session.close();
connection.close();
}效果如下

2. 发布订阅模式
发布者
@Test
public void testTopicMqProducter() throws Exception{ //1.创建链接工厂
ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://www.itzmn.com:61616"); //2.创建链接
Connection connection = factory.createConnection(); //3.开启连接
connection.start(); //4.创建一个session对象
/**
* 第一个参数，是否开启事务，如果开启 后面一个参数无意义
* 第二个参数，应答模式
*/
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); //5.创建一个目的地
Topic createTopic = session.createTopic("testTopic"); //6.创建一个内容提供者
MessageProducer producter = session.createProducer(createTopic); //7.发送消息
TextMessage QMessage = new ActiveMQTextMessage();
QMessage.setText("我是发布信息，张三抢到了手机11，rsad");
producter.send(QMessage); //8.关闭资源
session.close();
connection.close();
}订阅者
@Test
public void testTopicMqConsumer() throws Exception{ //1.创建链接工厂
ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://www.itzmn.com:61616"); //2.创建链接
Connection connection = factory.createConnection(); //3.开启连接
connection.start(); //4.创建一个session对象
/**
* 第一个参数，是否开启事务，如果开启 后面一个参数无意义
* 第二个参数，应答模式
*/
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); //5.创建一个目的地
Topic createTopic = session.createTopic("testTopic"); //6.创建一个内容提供者
MessageConsumer consumer = session.createConsumer(createTopic);
//获取数据
consumer.setMessageListener(new MessageListener() {
@Override
public void onMessage(Message message) {
TextMessage message2 = (TextMessage) message; try {
System.out.println(message2.getText());
} catch (JMSException e) { // TODO Auto-generated catch block
e.printStackTrace();
}
}
});
System.out.println("消费者1启动");
System.in.read(); //8.关闭资源
session.close();
connection.close();
}
@Test
public void testTopicMqConsumer2() throws Exception{ //1.创建链接工厂
ConnectionFactory factory = new ActiveMQConnectionFactory("tcp://www.itzmn.com:61616"); //2.创建链接
Connection connection = factory.createConnection(); //3.开启连接
connection.start(); //4.创建一个session对象
/**
* 第一个参数，是否开启事务，如果开启 后面一个参数无意义
* 第二个参数，应答模式
*/
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE); //5.创建一个目的地
Topic createTopic = session.createTopic("testTopic"); //6.创建一个内容提供者
MessageConsumer consumer = session.createConsumer(createTopic);
//获取数据
consumer.setMessageListener(new MessageListener() {
@Override
public void onMessage(Message message) {
TextMessage message2 = (TextMessage) message; try {
System.out.println(message2.getText());
} catch (JMSException e) { // TODO Auto-generated catch block
e.printStackTrace();
}
}
});
System.out.println("消费者2启动");
System.in.read(); //8.关闭资源
session.close();
connection.close();
}效果如下

queue模式
内容提供者
@Test
public void testSpringActiveMqProducter() {
ApplicationContext classPathXmlApplicationContext = new ClassPathXmlApplicationContext("classpath:applicationContext-activemq.xml");
JmsTemplate jmsTemplate = classPathXmlApplicationContext.getBean(JmsTemplate.class);
Destination destination = (Destination) classPathXmlApplicationContext.getBean("queueDestination");
jmsTemplate.send(destination,new MessageCreator() {
@Override
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage("生意来了，张三购买商品");
}
});
}这个消费者，要实现messagelistener的接口
public class MyMessageListener implements MessageListener{ @Override
public void onMessage(Message message) {
TextMessage message2 = (TextMessage) message; try {
System.out.println(message2.getText());
} catch (JMSException e) { // TODO Auto-generated catch block
e.printStackTrace();
}
}
}发布订阅模式
发布者
@Test
public void testSpringActiveMqTopicProducter() {
ApplicationContext classPathXmlApplicationContext = new ClassPathXmlApplicationContext("classpath:applicationContext-activemq.xml");
JmsTemplate jmsTemplate = classPathXmlApplicationContext.getBean(JmsTemplate.class);
Destination destination = (Destination) classPathXmlApplicationContext.getBean("topicDestination");
jmsTemplate.send(destination, new MessageCreator() {
@Override
public Message createMessage(Session session) throws JMSException {
return session.createTextMessage("又来生意啦，李四要购买手机");
}
});
}订阅者
public class MyTopicMessageListener implements MessageListener{ @Override
public void onMessage(Message message) { try {
TextMessage message2 = (TextMessage) message;
System.out.println(message2.getText());
System.out.println("我去减库存");
} catch (JMSException e) { // TODO Auto-generated catch block
e.printStackTrace();
}
}
}public class MyTopicMessageListener2 implements MessageListener{ @Override
public void onMessage(Message message) { try {
TextMessage message2 = (TextMessage) message;
System.out.println(message2.getText());
System.out.println("我去生成订单");
} catch (JMSException e) { // TODO Auto-generated catch block
e.printStackTrace();
}
}
}代码太乱，实验的话，请到码云下载，
