本文介绍了一个基于Java实现的ActiveMQ消息队列实用工具类。该工具类提供了发送和接收消息的功能，并通过示例代码展示了如何使用该工具进行消息的发送与接收。

1）<span style="font-family: Arial, Helvetica, sans-serif;">ActiveMQUtil.java </span>

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.DeliveryMode;
import javax.jms.JMSException;
import javax.jms.MessageConsumer;
import javax.jms.MessageProducer;
import javax.jms.Queue;
import javax.jms.Session;
import javax.jms.TextMessage;

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



public class ActiveMQUtil {

	private ConnectionFactory cf;
	
	public ActiveMQUtil() {
		// TODO Auto-generated constructor stub
		this(ActiveMQConnection.DEFAULT_USER,ActiveMQConnection.DEFAULT_PASSWORD,"tcp://127.0.0.1:61616");
	}
	
	public ActiveMQUtil(String activeMQUser,String activeMQPassword,String brokerUrl) {
		// TODO Auto-generated constructor stub
		cf=new ActiveMQConnectionFactory(activeMQUser, activeMQUser, brokerUrl);
	}
	
	public void send(String mesg,String destinationQueue){
		Connection conn=null;
		Session session=null;
		try {
			conn=cf.createConnection();
			conn.start();
			session=conn.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
			Queue dest=session.createQueue(destinationQueue);
			MessageProducer producer=session.createProducer(dest);
			producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);
			producer.send(session.createTextMessage(mesg));
			session.commit();
			conn.stop();
		} catch (JMSException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}finally{
			if(null!=session)
				try {
					session.close();
				} catch (JMSException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			if(null!=conn)
				try {
					conn.close();
				} catch (JMSException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
		}
		
	}
	
	public String receive(String destinationQueue) throws JMSException{
		Connection conn=null;
		Session session=null;
		TextMessage message=null;
		try {
			conn=cf.createConnection();
			conn.start();
			session=conn.createSession(Boolean.TRUE, Session.AUTO_ACKNOWLEDGE);
			Queue dest=session.createQueue(destinationQueue);
			MessageConsumer	 consumer=session.createConsumer(dest);
		    message = (TextMessage) consumer.receive(100000);
			session.commit();
			conn.stop();
		} catch (JMSException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}finally{
			if(null!=session)
				try {
					session.close();
				} catch (JMSException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			if(null!=conn)
				try {
					conn.close();
				} catch (JMSException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
		}
		return message.getText();
	}
}

2)测试类：

import javax.jms.JMSException;


public class Test {

	/**
	 * @param args
	 * @throws JMSException 
	 */
	public static void main(String[] args) throws JMSException {
		// TODO Auto-generated method stub
		ActiveMQUtil amqUtil=new ActiveMQUtil();
		//amqUtil.send("hellow", "hellowWorld");
		System.out.println(amqUtil.receive("hellowWorld"));
	}

}
