ActiveMQ的一个简单实例-ActiveMQ接收+发送消息 JMS消息框架——ActiveMQ
最近由于公司项目需要 -ActiveMQ接收+发送消息，用的是ActiveMQ。由于这方面网上的例子不是很多，而且有的也不完整。于是经过几天的摸索学习，在网上找到了合适的方案。
我的 IT技术资源库 http://itlib.tk/
ProducerTool.java用于发送消息：
java 代码
package homework;
import javax.jms.Connection;
import javax.jms.DeliveryMode;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;
import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;
public class ProducerTool {
private String user = ActiveMQConnection.DEFAULT_USER;
private String password = ActiveMQConnection.DEFAULT_PASSWORD;
private String url = ActiveMQConnection.DEFAULT_BROKER_URL;
private String subject = "TOOL.DEFAULT";
private Destination destination = null;
private Connection connection = null;
private Session session = null;
private MessageProducer producer = null;
// 初始化
private void initialize() throws JMSException, Exception {
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(
user, password, url);
connection = connectionFactory.createConnection();
session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
destination = session.createQueue(subject);
producer = session.createProducer(destination);
producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
}
// 发送消息
public void produceMessage(String message) throws JMSException, Exception {
initialize();
TextMessage msg = session.createTextMessage(message);
connection.start();
System.out.println("Producer:->Sending message: " + message);
producer.send(msg);
System.out.println("Producer:->Message sent complete!");
}
// 关闭连接
public void close() throws JMSException {
System.out.println("Producer:->Closing connection");
if (producer != null)
producer.close();
if (session != null)
session.close();
if (connection != null)
connection.close();
}
}
ConsumerTool.java用于接受消息，我用的是基于消息监听的机制，需要实现MessageListener接口，这个接口有个onMessage方法，当接受到消息的时候会自动调用这个函数对消息进行处理。
java 代码
package homework;
import javax.jms.Connection;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.MessageConsumer;
import javax.jms.Session;
import javax.jms.MessageListener;
import javax.jms.Message;
import javax.jms.TextMessage;
import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;
public class ConsumerTool implements MessageListener {
private String user = ActiveMQConnection.DEFAULT_USER;
private String password = ActiveMQConnection.DEFAULT_PASSWORD;
private String url = ActiveMQConnection.DEFAULT_BROKER_URL;
private String subject = "TOOL.DEFAULT";
private Destination destination = null;
private Connection connection = null;
private Session session = null;
private MessageConsumer consumer = null;
// 初始化
private void initialize() throws JMSException, Exception {
ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(
user, password, url);
connection = connectionFactory.createConnection();
session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
destination = session.createQueue(subject);
consumer = session.createConsumer(destination);
}
// 消费消息
public void consumeMessage() throws JMSException, Exception {
initialize();
connection.start();
System.out.println("Consumer:->Begin listening...");
// 开始监听
consumer.setMessageListener(this);
