title: Spring MVC @RequestBody and partial object/json binding
body: <p>I have a large object which can be updated in a few steps. I'am facing a partial binding problem. My service consumes json and I can not use @InitBinder along with @RequestBody. Cutting this object to a few small ones is not good a solution, because there is a lot of cross-field validations between steps.</p>
  
  <p>Do you have any ideas how to solve this? I'am looking for a clean solution like: registering a specific object mapper for given @RequestMapping or something like that. Thanks for help.</p>
