Single URL for many rest services

maciavelli Sep 23, 2015 2:32 AM

Hello.

I am developing REST services and they have to use single URL. For example http://localhost:8080/broker/web. Each REST service packaged as JAR according to tasks they intented(customertasks.jar, internalprovider.jar, etc). How to make REST services in many jars to use single URL?

At this moment I implemented this using proxy service in project Gate as shown below:

It uses REST service and reference binding, is just resend String message to the target method in REST binding. And so each time when I deploy new jar I have to rebuild my Gate, add new contracts(methods) in REST reference interface, add transformers(because Endpoint in picture above accepts String requests).

May be exists another more conviniant way?

Which version of SwitchYard are you using? It is possible to deploy more jars to the same context.Here are two jars split from rest-binding quickstart that deploys to the url

http://localhost:8080/rest-binding

Each jar has one service each, part2 has http://localhost:8080/rest-binding/warehouse and part1 has http://localhost:8080/rest-binding/order

Just copy the two jars to SwitchYard 2.0 enabled EAP/AS7 deployments folder and see.

Hello, Magesh. I am using SY 2.0. I tried using same context path for 2 jars but only the last will be used. I am had deployed your jars but path could not understand your idea. Could you clarify the actions what to do?
As I see both jars uses single Context path, and as I understood the full URL will be different, for example http://localhost:8080/rest-binding/order for method newOrder and http://localhost:8080/rest-binding/warehouse for method updateItem. But the goal is to use single URI for all methods and when processing the request decide which jar to call and which method in that jar will be invoked.

I think you need a content based router to front the rest services. Each rest service jar can have its own URLs deployed in its own jar and the CBR will internally invoke the appropriate REST URLs and respond back. Have a look at cbr example in quickstarts https://github.com/jboss-switchyard/quickstarts/tree/master/rules-camel-cbr

Hi. Thank you, Magesh.
My decision is to use to make Gate project with REST binding service which has a SCA reference binding to other projects(jars). The core of Gate is Camel content based Route, which resends incoming message from REST binding service to concrete target SCA reference.
This is my Gate:
This is example of project which will be called from Gate:
So single point for all requests is Gate project, which redirects message to concrete jar.
