Creating REST Clients for JAX-RS based Webservices with Netflix Feign

Thursday, October 22nd, 2015

For us developers there plenty of libraries exist helping us in deriving and generating clients for existing RESTful web-services and I have already covered some of the in this blog (e.g. the JAX-RS Client API). Nevertheless, I’d like to share my experience with another interesting lightweight library here: Netflix Feign.

Feign offers a nice fluent-builder API, a rich integration forĀ  common libraries and APIs like JAX-RS, Jackson, GSON, SAX, JAX-B, OkHttp, Ribbon, Hystrix, SLF4J and more and last bot not least, it is setup easy and the service contracts are specified using interfaces and annotations.

In the following tutorial I’d like to demonstrate how to derive a service binding from a simple, JAX-RS based RESTful web-service, how to create the service adapter using the integrated builder and at last, performing CRUD operations.


REST-assured vs Jersey-Test-Framework: Testing your RESTful Web-Services

Monday, September 5th, 2011

Today we’re going to take a look at two specific frameworks that enables you to efficiently test your REST-ful services: On the one side there is the framework REST-assured that offers a nice DSL-like syntax to create well readable tests – on the other side there is the Jersey-Test-Framework that offers a nice execution environment and is built upon the JAX-RS reference implementation, Jersey.

In the following tutorial we’re going to create a simple REST service first and then implement integration tests for this service using both frameworks.

The title of this article might be misleading due to the fact that I am not going to compare both frameworks to choose a winner, just showing the different approach ..


Contract-First Web-Services using JAX-WS, JAX-B, Maven and Eclipse

Tuesday, August 23rd, 2011

Using the contract-first approach to define a web service offers some advantages in contrast to the code-first approach.

In the following tutorial we’re going to take a look at some details of this approach and we’re going to implement a real SOAP service using JAX-WS, Maven and the Eclipse IDE.

Finally we’re going to run our service implementation on an embedded Jetty instance and we’re going to take a look at soapUI and how to test our service using this neat tool.


Creating a REST Client Step-by-Step using JAX-RS, JAX-B and Jersey

Thursday, November 25th, 2010

Often in a developer’s life there is a REST service to deal with and nowadays one wants a fast and clean solution to create a client for such a service.

The following tutorial shows a quick approach using JAX-RS with its reference implementation, Jersey in combination with JAX-B for annotation driven marshalling between XML or JSON structures and our Java-Beans.
