To run this example, you will need to do the following:

• Update the application.properties file with your MySQL username and password
• Create a new database schema with name springboot_activemq_example
• If you wish to used a different database / schema, you will need to override values in application.properties
• Example uses an embedded ActiveMQ Broker. If you wish to use an external broker, you will need to override the appropriate Spring Boot Properties.

Application flow:

• Once the application is started, open the same in a browser http://localhost:8080
• Create a new Product record
• Notice that the value for "Are Messages Sent" in the http://localhost:8080/product/show/1 is set to false.
• There is a link at the bottom of this record "Send message for product through queue listener"
• When this link is clicked, a message is put in an activemq queue, the browser is redirected back to the product show page without getting blocked.
• This message is read and processed by MessageListener class.
• On the browser, refreshing the page: http://localhost:8080/product/show/1
• You will see the message sent and message count increase (if you click the send link more than once)
• Expect a short delay in processing the messages.
