How to build Microservices with Intershop

Intershop’s Microservices

Everybody talks about microservices. Since e-Commerce systems are complex and consist of many components, microservices as self-contained, largely decoupled units integrate perfectly into Intershop’s e-Commerce systems. Intershop products, like Intershop Commerce Management, are build using strictly service oriented and modular approaches. The latest release also comes with several microservices, namely a service that handles recurring orders and a service that schedules tasks. These microservices are build on top of a very lightweight technology stack. Other microservices might be build using this stack as well or could easily use their completely independent technologies. This blog-entry shows how a simple microservice can be created and run in a couple of minutes. The created example might be a starting point for your own services or can serve as documentation and quick tutorial.

Create Your Simple Microservice

In this blog entry a new Intershop Studio release is (version 4.6.2) used as well as templates that will ship along with ICM 7.9.
In order to create you a new microservice project you can launch the wizard ‘Create Intershop Development Artifact’:

and select ‘Microservice with a simple application that computes welcome messages’:

Enter some data on the next page, namely the location of the new project, a name as well as some information about the service discovery and artifact-repository location:

Hit ‘Finish’. That’s all. You just created a fully functional Microservice.

Discover and Run Your Simple Microservice

It can be build, run and deployed using gradle or directly from within Intershop Studio. The created microservice also comes with a small Cheat Sheet that can help you to discover its features and components. If you follow the steps in it you can e.g. open and inspect the created Java-class which functions as the main entrance point of you service.


Probably of more interest is the class  since it declares and implements the actual REST-API of your service. This simple service has just two simple operations that create welcome messages.


It’s time to start you service. Just select ApplicationServer[HelloService].launch and invoke ‘Run as’ ApplicationServer[HelloService]. A console should open. Verify that the service starts and states

11:06:30.813 [main] INFO  c.i.c.w.c.server.ApplicationServer - Server listens on ''. Of course, the actual URL will be different. You also see that an API documentation is

available with the service. It says on the console:

11:06:30.813 [main] INFO  c.i.c.w.c.server.ApplicationServer - View documentation about this service here: ''

Note that the service uses Swagger annotations (Swagger.IO) and comes with an integrated Swagger-UI which can be used to test and analyze the service:


Because the service just uses simple REST you can also use the browser and let it compute welcome messages, either as simple text or simple html:

Next Steps

Feel free to adapt and try the created microservice. For example add new API-methods, use JSON or XML to put or post and get data. Stay tuned for additional blog-entries that will cover aspects like persistence, service discovery and much more.

      This article is about writing Microservices to be used from Intershop’s Application Server. Write them with whatever you like with PHP or Spring even. We like it light-weight the reason why we avoided Spring. Welcome to 2017!
