Bridging between JMS and RabbitMQ (AMQP) using Spring Integration

Bridging between JMS and RabbitMQ (AMQP) using Spring Integration

Today’s data climate is fast-paced and it’s not slowing down. Here’s why your current integration solution is not enough. Brought to you in partnership with Liaison Technologies.

An old customer recently asked me if I had a solution for how to integrate between their existing JMS infrastructure on Websphere MQ with RabbitMQ.


Although I know that RabbitMQ has the shovel plugin which can bridge between Rabbit instances I've yet not found a good plugin for JMS <-> AMQP forwarding.

The first thing that came to my mind was to utilize a Spring Integration mediation as SI has excellent support for both JMS and Rabbit.


Curious as I am I started a PoC and this is the result. It takes messages of a JMS queue and forwards to an AMQP exchange that is bound to a queue the consumer application is supposed to listen to. I used an external HornetQ instance in JBoss 6.1 as the JMS Provider, but I am 100% secure that the same setup would work for Websphere MQ as they both implement JMS.


Be aware that I've done no performance tweaking or QoS setup yet as this is just a proof-of-concept. For a real setup you'd probably have to think about delivery guarantees versus performance and etc...


The code will be available at a GitHub repository near you soon..
