subscribe to multiple topics inside same session?

Hi,
Yes! Using our integration with Spring would be a great way to do this.
Using our Spring Boot JMS Starter & the @JmsListener java annotation would likely be the easiest way to get what you want.
You can do something like seen in the code below.

package com.solace.samples.spring.boot;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.TextMessage;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.jms.annotation.JmsListener;

@SpringBootApplication
public class SpringBootReceiver {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootReceiver.class, args);
    }

    @JmsListener(destination = "abc/topic1")
    public void handleFoo(Message message) {

        if (message instanceof TextMessage) {
            TextMessage tm = (TextMessage) message;
            try {
                System.out.println("TextMessage Received on destination "+ tm.getJMSDestination());
            } catch (JMSException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        } else {
            System.out.println("Message of another type was received");
        }
    }


    @JmsListener(destination = "abc/topic2")
    public void handleBar(Message message) {

        if (message instanceof TextMessage) {
            TextMessage tm = (TextMessage) message;
            try {
                System.out.println("TextMessage Received on destination " + tm.getJMSDestination());
            } catch (JMSException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        } else {
            System.out.println("Message of another type was received");
        }
    }
}

Note that by default when using the @JmsListener annotation Spring Boot autoconfigures objects that are set to listen from a queue so if you want to subscribe to a topic you'll need to set this property in your application.properties file (or equivalent).

spring.jms.pub-sub-domain=true

Hope that helps!

Hi @bxb,

I don't know what the issue is off the top of my head. Maybe connecting to the wrong message vpn if you have multiple? This thread is pretty old so only people who commented on it will get notified, can you create a new thread and share more of your code/config? By creating a new discussion more people will see it.

thank you!
