Handling RabbitMQ broker re-connections

The RabbitMQ Java Client Library has default support for auto-recovery (since version 4.0.0). Hence the client will try to recover a broken connection unless you explicitly disable it.

If you want to fine-tune the retry mechanism, then the examples given in the below link would help.

Or alternatively, you can use the super easy Spring RabbitTemplate class that has retry options. The RabbitTemplate class wraps the RabbitMQ Java client and provides all the goodies of Spring.
