activemq消息生产者与消息消费者简单例子

消息生产者HelloQueueProducer.java

package activemq.test;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.DeliveryMode;
import javax.jms.Destination;
import javax.jms.Message;
import javax.jms.MessageProducer;
import javax.jms.Session;

import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;

public class HelloQueueProducer {
public static void sendMessage(String activemq_url, String activemq_user, String activemq_pw, String msg, String queue_name) {
try {
//通过username,password,url创建连接工厂接口
ConnectionFactory factory = new ActiveMQConnectionFactory(activemq_user, activemq_pw, activemq_url);
//通过连接工厂创建一个新的连接接口
Connection connection = factory.createConnection();
//打开连接
connection.start();
//通过连接接口创建一个会话接口 消息应答模式：Session.AUTO_ACKNOWLEDGE
Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
//会话接口创建有关主题的目标接口
Destination destination = session.createQueue(queue_name);
//会话接口再根据目标接口来创建一个消息生产者接口
MessageProducer producer = session.createProducer(destination);
producer.setDeliveryMode(DeliveryMode.PERSISTENT);
//调用会话生成一个文本消息
// Message message = session.createTextMessage(msg);

//调用会话生成一个对象消息
QueueModel model = new QueueModel();
model.setId("1");
model.setIdType(1);
model.setOperType(1);
model.setDesc("修改");
Message message = session.createObjectMessage(model);
//通过生产者接口Send将消息发布到ActiveMQ服务器
producer.send(message);
//关闭会话
session.close();
//关闭连接
connection.close();

} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
// sendMessage("tcp://localhost:61616", ActiveMQConnection.DEFAULT_USER, ActiveMQConnection.DEFAULT_PASSWORD, "发送消息：Hello ActiveMQ Text Message！", "test_queue");
