<h2>GSONJERSEYPROVIDER IS AN EXAMPLE ON HOW TO USE THE GOOGLE GSON LIBRARY AS AN PROVIDER ON JERSEY JAX-RS APPLICATIONS.</h2><span>In times where Spring.io or the PlayFramework are state of the art technologies there are projects in the world which needs some extra attention, maybe an&nbsp;old backend where only the frontend should be relaunched. Of course this can be done, but why not invest about two&nbsp;days to add a lot new functionality and make the frontend team smile and work faster and easier with well formed Json’s?&nbsp;<img alt="" src="http://lanora.io/wp-includes/images/smilies/icon_smile.gif">&nbsp;</span>Gson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object. Gson can work with arbitrary Java objects including pre-existing objects that you do not have source-code of.&nbsp;There are a few open-source projects that can convert Java objects to JSON. However, most of them require that you place Java annotations in your classes; something that you can not do if you do not have access to the source-code. Most also do not fully support the use of Java Generics. Gson considers both of these as very important design goals.The problem: we have&nbsp;to call toJson, fromJson on our own, which isn’t that nice. So we wanted to add some functionality combined&nbsp;with Jersey &amp; RESTFull Webservices.<span>The Idea: using the GsonComponent as an Provider for @application/json calls – it’s not that difficult to do that, quick search on google and we found an version of the GsonJerseyProvidor by&nbsp;<a href="http://eclipsesource.com/blogs/2012/11/02/integrating-gson-into-a-jax-rs-based-application/" target="" rel="">@eclipsesource</a>, but still there is only the toJson, fromJson capsuled – no configuration, no “structure”. Thomas Pink than told us to build an structure so he can use it with the&nbsp;<a href="http://emberjs.com/" target="" rel="">emberjs</a>&nbsp;framework and his&nbsp;<a href="http://emberjs.com/guides/models/the-rest-adapter/" target="" rel="" title="Link: http://emberjs.com/guides/models/the-rest-adapter/">REST Adapter&nbsp;</a>- of course this was a huge step – a backend developer who will developer hand in hand when an frontend developer? After a while we found a really nice structure, at first it was a little bit of “too much code” but after a while it became really common to use.<br>Check it out:&nbsp;<a href="http://lanora.io/2014/11/gson-jersey-provider/">http://lanora.io/2014/11/gson-jersey-provider/</a><br><br></span><h3></h3><h3></h3>
