title: Get RequestBody and ResponseBody at HandlerInterceptor
body: <p>Logic I have to implement is logging all requests with body served to DB.</p>
  
  <p>So I decided to use: <code>afterCompletion</code> method of <code>HandlerInterceptor</code>.
  There are two parameters passed to this method <code>HttpServletRequest</code> and <code>HttpServletResponse</code> among the others.</p>
  
  <p>Question is: how to get <code>RequestBody</code> and <code>ResponseBody</code> from supplied objects?</p>
  
  <p>As far as I know at Controller we can use <code>@RequestBody</code> and <code>@ResponseBody</code>. Can I reuse them at <code>HandlerInterceptor</code>?</p>
