title: Is it possible to use something like @RequestParam for JSON in spring rest services?
body: <p>I use Spring boot and i am writing rest services server in Spring
  I have a lot of different requestmappings, and i need to accept content in json</p>
  
  <p>I can do that with <code>@RequestBody</code> annotation
  But in this case i will have a lot of POJO classes for every request and every possible response.</p>
  
  <p>And a lot of JSONs I need to send and receive are very simple - one or two or three values</p>
  
  <p>Is it possible to use something like <code>@RequestParam("field1_from_my_json")</code> and <code>@RequestParam("field2_from_my_json")</code> for extracting the JSON fields as the request parameters, and not to create the new POJO every time?</p>
