Spring 3.2 Rundown, Miscellaneous

So, in this final part of my excursion into new Spring territory, I’ll talk about a few trends and tools noted in the “3.2 era”. This blog post will go high and low while trying to follow a red line, let’s see how it goes!

First of all, let’s take a look at some of the tools that leverage the ongoing boom in REST-ful API:s.

Spring HATEOAS is a framework helping out with writing HATEOAS compliant REST-interfaces (which is really a fundamental principle of REST!). Basically, a client should only take actions on a resource that were described in representations previously received from the server. You could say that the client should be able to be agnostic in terms of what resources are available, and how they are linked. So, not surprisingly, this Spring framework has support for adding this type of information to the representations the server sends back to the client. It can help you keep track of how to create the necessary relative links to other resources in your application. I believe this principle of REST is pretty fantastic, yet not fully leveraged by many teams, and I encourage you to take look!

Spring REST-shell is a tool used to help REST developers test and explore their interfaces. The command line-style shell have several commands and features such as discovering resources, following paths within the interface, setting the HTTP request headers and posting JSON (although that is somewhat clunky). An intended use of this shell is together with the HATEOAS framework, fully leveraging HATEOAS-style links. An example would be that a resource which has a “rel” linking to another resource, can easily be followed via commands instead of having to manipulate the resource URL.

The above tools can actually be used together with Spring Data Rest to, with very little boilerplate code, create a HATEOAS compliant REST-interface on top of your model.

Finally, a small reflection that most of the Spring projects on Github now seem to use Gradle instead of Maven. It’s not particularly new that Gradle is the new kid on the block, however you should take notice that things are happening here. Apparently, ThoughtWorks goes so far as to put Gradle in the ‘Adopt’ quadrant in their 2013 technology radar, whilst Maven falls back to ‘Hold’.
