Because a lot of my current projects are using JAX-RS in different versions I’d like to write down and share some frequently used snippets for implementing RESTful web-services with the JAX-RS specification here.
JAX-RS 2.0 aka JSR 339 not also specifies the API to build up a RESTful webservice but also enhances the client side API to easen up the process of writing a client for a REST service.
In the following tutorial we’re building up a client for a ready-to-play REST service and explore the different new options e.g. how to handle requests in a synchronous or asynchronous way, how to add callback handlers for a request, how to specify invocation targets to build up requests for a later execution or how to filter the client-server communication using client request filters and client response filters.
There are many frameworks out there to facilitate testing RESTful webservices but there is one framework I’d like to acquaint you with my favourite framework named REST-assured.
REST-assured offers a bunch of nice features like a DSL-like syntax, XPath-Validation, Specification Reuse, easy file uploads and those features we’re going to explore in the following article.
With a few lines of code and Jersey I have written a RESTful web service that allows us to explore the features of the REST-assured framework and to run tests against this service.
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 ..
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.
