Solace Spring JMSListner

Team, I am new to the Solace and i am currently using in the Solace SpringBoot JMS.

I have created a Queue and Published 500 Message to it. I want to implement a Multithreading behavior to my consumer which will consume the message parallelly and process instead of one by one.

I have added the minimum concurrency as 5 and maximum 10. When i start the application , i can see 5 consumers are in active but only one consumer is processing all the Messages. I want to know how we can use all the consumers and process the messages parlelly.

Sample Code:

@JmsListener(destination = "Q/tab/Consumer/test", concurrency = "5-10" )
    public void handle(Message message) {

        counter = counter+1;
        Date receiveTime = new Date();
        System.out.println(
                "Consumer Process started at Received at " + new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS").format(receiveTime));
        if (message instanceof TextMessage) {
            TextMessage tm = (TextMessage) message;
            try {

                tm.getText();

                System.out.println(Thread.currentThread().getId());
                System.out.println("Processed ----" + counter + " so far" );

            } catch (JMSException e) {
                e.printStackTrace();
            }
        } else {
            System.out.println(message.toString());
        }
    }
