What is the best way to go over a JMS queue and get all the messages in it?

Answer 1

Java 8 & Spring Boot

   public int countPendingMessages(String destination) {
    // to an Integer because the response of .browse may be null
    Integer totalPendingMessages = this.jmsTemplate.browse(destination, (session, browser) -> Collections.list(browser.getEnumeration()).size());

    return totalPendingMessages == null ? 0 : totalPendingMessages;
   }
