spring mvc - Intercept @RequestBody after serialization but before controller -

-

my request body objects implement interface call auditable, username , lastupdate timestamp set. intercept calls controller functions after serialization before hits controller can can these values in single place.

i looked @ handlerinterceptor.prehandle method executes before serialization. suggestion on how can make happen?

you can use controlleradvice , can in these scenarios. intercepts controller requests , can access serialized domain object in method. can pretty args requestmapping method takes. hope helps. 

@controlleradvice public class controlleradvisor {      @modelattribute     public void addattributes(httpservletrequest request, httpservletresponse response,model model, @requestbody domainobject domain) {         domain.setusername("test");         // set other items want do.     }     }
