Jersey REST service as a proxy

Question

I need to build a REST API (Jersey 2) that should act as a proxy to an external service for certain calls (all the urls with a certain path in it). I need to get some statistics out of those calls (number of invocations), so in addition to proxy the calls I need to have some small logic for all of them.

What would the best way to achieve this in jersey? I am not familiar with the Jersey framework, so I'll appreciate if anybody can point me to the right direction!

Thanks! Roberto

Answer 1

You could use the Metrics library. It works with Jersey and can get you a bunch of data points. http://metrics.codahale.com/

Answer 2

You could use Hystrix (from Netflix) within Jersey to achieve this. It provides very nice stats. Check this dashboard provided by Hystrix.
