Create Consumer Project

Create Java Project in Eclipse. Right click the project select Build Path\Configure Build Path menu. In Libraries tab, select all jar files above to the project. Besides, we need add appserv-rt library in glassfish4\glassfish\lib folder from GlassFish Server as photo below:

Consumer Project Structure

Create Message Listener class

This class contains methods to receive messages from destination

package demo.spring_jms;

import javax.jms.MapMessage;
import javax.jms.Message;
import javax.jms.MessageListener;

public class MapMessageListener implements MessageListener {

	@Override
	public void onMessage(Message message) {
		try {
			if (message instanceof MapMessage) {
				MapMessage mapMessage = (MapMessage) message;
				System.out.println("Student Info");
				System.out.println("Id: " + mapMessage.getString("id"));
				System.out.println("Full Name: " + mapMessage.getString("fullName"));
				System.out.println("Age: " + mapMessage.getInt("age"));
				System.out.println("Status: " + mapMessage.getBoolean("status"));
				System.out.println("Score: " + mapMessage.getDouble("score"));
			}
		} catch (Exception e) {
			System.err.println(e.getMessage());
		}
	}

}

Spring JMS Configuration File

The Spring configuration shows a context:component-scan that picks up the JMS listener.

Run Application

package demo.spring_jms;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {

	public static void main(String[] args) {

		try {
			ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
		} catch (Exception e) {
			System.err.println(e.getMessage());
		}

	}

}

Output

Student Info
Id: st01
Full Name: ABC
Age: 20
Status: true
Score: 7.8
