So using JMS and ActiveMQ, I can be sure that my message sent from my Spring Boot application using JmsTemplate will reach it's destination application even if that destination application is down at the time I send the message to ActiveMQ. As when the destination application starts up, it grabs the message from the queue. Great!
However.
What happens if my Spring Boot application tries to send a JMS message to a queue on the ActiveMQ server, but the ActiveMQ server is down at that point or the network is down and I get a connection refused exception?
What is the recommended way to make sure my application keeps trying to re-sends the message to ActiveMQ until it is successful? Is this something I have to develop into my application myself? Are there any nifty Spring tools or annotations which do this for me? Any advice on best practice or how I should be handling this scenario?
