基于Tomcat + JNDI + ActiveMQ实现JMS的点对点消息传送

首先:在你的tomcat conf的context.xml 文件的Context标签下配置：

     <Resource name="queue/connectionFactory"    
                auth="Container"    
                type="org.apache.activemq.ActiveMQConnectionFactory"  
                description="JMS Connection Factory"  
                factory="org.apache.activemq.jndi.JNDIReferenceFactory"  
                brokerURL="tcp://localhost:61616"  
                brokerName="LocalActiveMQBroker" />  
                  
<Resource name="queue/queue0"    
                auth="Container"    
                type="org.apache.activemq.command.ActiveMQQueue"  
                description="My Queue"  
                factory="org.apache.activemq.jndi.JNDIReferenceFactory"  
                physicalName="TomcatQueue" />

然后代码中下载

ActiveMQ的客户端相关包:

<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-client</artifactId>
    <version>5.14.0</version>
</dependency>

然后写测试代码:

import javax.jms.DeliveryMode;
import javax.jms.Queue;
import javax.jms.QueueConnection;
import javax.jms.QueueConnectionFactory;
import javax.jms.QueueReceiver;
import javax.jms.QueueSender;
import javax.jms.QueueSession;
import javax.jms.Session;
import javax.jms.TextMessage;
import javax.naming.InitialContext;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping("/jms/tests")
@ResponseBody
public class TestAction {

    /**
     * 发送消息
     */
    @RequestMapping("/send")
    public void send() {
        try {
            // get the initial context
            InitialContext context = new InitialContext();

            // lookup the queue object
            Queue queue = (Queue) context.lookup("java:comp/env/queue/queue0");

            // lookup the queue connection factory
            QueueConnectionFactory conFactory = (QueueConnectionFactory) context
                    .lookup("java:comp/env/queue/connectionFactory");

            // create a queue connection
            QueueConnection queConn = conFactory.createQueueConnection();

            // create a queue session
            QueueSession queSession = queConn.createQueueSession(false, Session.DUPS_OK_ACKNOWLEDGE);

            // create a queue sender
            QueueSender queSender = queSession.createSender(queue);
            queSender.setDeliveryMode(DeliveryMode.NON_PERSISTENT);

            // create a simple message to say "Hello World"
            TextMessage message = queSession.createTextMessage("Hello World");

            // send the message
            queSender.send(message);

            // print what we did
            System.out.println("Message Sent: " + message.getText());

            // close the queue connection
            queConn.close();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

    /**
     * 接收消息
     */
    @RequestMapping("/reveive")
    public void reveive() {
        try {
            // get the initial context
            InitialContext context = new InitialContext();

            // lookup the queue object
            Queue queue = (Queue) context.lookup("java:comp/env/queue/queue0");

            // lookup the queue connection factory
            QueueConnectionFactory conFactory = (QueueConnectionFactory) context
                    .lookup("java:comp/env/queue/connectionFactory");

            // create a queue connection
            QueueConnection queConn = conFactory.createQueueConnection();

            // create a queue session
            QueueSession queSession = queConn.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);

            // create a queue receiver
            QueueReceiver queReceiver = queSession.createReceiver(queue);

            // start the connection
            queConn.start();

            // receive a message
            TextMessage message = (TextMessage) queReceiver.receive();

            // print the message
            System.out.println("Message Received: " + message.getText());

            // close the queue connection
            queConn.close();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

最后访问链接，先请求发送消息方法，然后请求接收消息方法，打开你的activemq服务器，可观察消息的发送与接收

ok....测试例子通过

该例子使用JMS规范提供的通用接口来写的。。。
