Bridging Between JMS and RabbitMQ (AMQP) Using Spring Integration
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..
