activeMq是一种消息中间件,在很多电商的系统中都有用到!
我们是基于windows的测试,所以之前应该启动服务端!
启动完成之后进行代码的测试!
package com.activemq;
import org.apache.activemq.ActiveMQConnectionFactory;
import javax.jms.*;
public class Producer { //生产者
public static void main(String[] args) throws JMSException {
ActiveMQConnectionFactory activeMQConnectionFactory=new ActiveMQConnectionFactory("tcp://localhost:61616");
Connection connection = activeMQConnectionFactory.createConnection();
connection.start();
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
Queue queue = session.createQueue("huangshuai_Message");
MessageProducer producer = session.createProducer(queue);
TextMessage textMessage = session.createTextMessage("HS生产了一条消息");
System.out.println(textMessage.getText());
producer.send(textMessage);
producer.close();
session.close();
connection.close();
}
}
然后我们启动消费者,接受消息!
package com.activemq;
import org.apache.activemq.ActiveMQConnectionFactory;
import javax.jms.*;
import java.io.IOException;
public class Consumer {
public static void main(String[] args) throws JMSException, IOException {
//1.创建连接工厂
ConnectionFactory connectionFactory=new ActiveMQConnectionFactory("tcp://localhost:61616");
//2.获取连接
Connection connection = connectionFactory.createConnection();
//3.启动连接
connection.start();
//4.获取session (参数1:是否启动事务,参数2:消息确认模式)
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
//创建队列对象
Queue queue = session.createQueue("huangshuai_Message");
//创建消费者
MessageConsumer consumer = session.createConsumer(queue);
//进行事件的监听
consumer.setMessageListener(new MessageListener() {
public void onMessage(Message message) {
TextMessage textMessage=(TextMessage) message;
try {
System.out.println("接收到消息"+textMessage.getText());
} catch (JMSException e) {
e.printStackTrace();
}
}
});
System.in.read();
//关闭资源
consumer.close();
session.close();
connection.close();
}
}
至此,我们就完成了基于队列的基本测试!
