Create Producer 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:

Producer Project Structure

Spring JMS Configuration File

The Spring configuration shows a context:component-scan that picks up the JMS producer and listener. Then a JMS connection factory is made for the JmsTemplate to use. The template will be used by the producer to send messages.

Create Message Producer class

This class contains methods to send messages to destination

package demo.spring_jms;

import javax.jms.JMSException;
import javax.jms.MapMessage;
import javax.jms.Message;
import javax.jms.Session;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.jms.core.MessageCreator;
import org.springframework.stereotype.Component;

@Component("mapMessageProducer")
public class MapMessageProducer {

	@Autowired
	private JmsTemplate jmsTemplate;

	public void sendMessage() {
		jmsTemplate.send(new MessageCreator() {
			@Override
			public Message createMessage(Session session) throws JMSException {
				MapMessage mapMessage = session.createMapMessage();
				mapMessage.setString("id", "st01");
				mapMessage.setString("fullName", "ABC");
				mapMessage.setInt("age", 20);
				mapMessage.setBoolean("status", true);
				mapMessage.setDouble("score", 7.8);
				return mapMessage;
			}
		});
	}

}

Run Application

The program will automatically send the map message every 1 second

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");
			MapMessageProducer mapMessageProducer = context.getBean("mapMessageProducer", MapMessageProducer.class);
			while (true) {
				mapMessageProducer.sendMessage();
				Thread.sleep(1000);
			}
		} catch (Exception e) {
			System.err.println(e.getMessage());
		}

	}

}
