title: Filling a java object from a json object
body: <p>I was wondering if something existed to directly fill the attributes of a java object from a json object?
  Something like : 
  TotoObject toto = fill(JsonObject);</p>
  
  <p>I'm doing this using getter and setter at the moment, but it's pretty long and it makes my code look like crap when I have an object with a lot of attribute.</p>
  
  <p>Thank you.</p>
