    copied!<p>I'm trying build my application using REST and Spring MVC. For some entities I have special page for update. After data submit it validated. If there are no errors it's redirecting to view of this entity otherway to edit page. haw I must pass data (entity and validator result) between controllers? </p> <p>here implementation with some very bad practice.</p> <pre><code>@RequestMapping(method = RequestMethod.PUT, value = "/workers/{id}") public ModelAndView update(@PathVariable final Long id, @Valid Worker entity, Errors errors, NativeWebRequest request) { ModelAndView model = new ModelAndView(); entity.setId(id); if (errors.hasErrors()) { request.setAttribute("entity", entity, RequestAttributes.SCOPE_SESSION); request.setAttribute("errors", errors.getAllErrors(), RequestAttributes.SCOPE_SESSION); model.setViewName("redirect:/workers/" + entity.getId()+ "/edit"); } else { System.out.println("upd-done"); service.update(entity); model.setViewName("redirect:/workers/" + entity.getId()); model.addObject(entity); } return model; } @RequestMapping(method = RequestMethod.GET, value = "/workers/{id}/edit") public ModelAndView updatePage(@PathVariable Long id, NativeWebRequest request) { ModelAndView model = new ModelAndView(); DomainObject entity = (DomainObject)request.getAttribute("entity", RequestAttributes.SCOPE_SESSION); model.addObject("entity", entity != null ? entity : service.get(id)); model.setViewName(names.provideViewName(Pages.EDIT)); return model; } </code></pre> <p>here form for edit</p> <pre><code>&lt;form id="entity" action="/workers/6" method="post"&gt;&lt;input type="hidden" name="_method" value="PUT"/&gt; foo &lt;input id="foo" name="foo" type="text" /&gt;&lt;/td&gt; &lt;input type="submit" value="Save Changes" /&gt; &lt;/form&gt; </code></pre> <p>Thanks.</p>
