@RequestMapping(value="/getSalesInfo", method = RequestMethod.GET) public @ResponseBody String getLogin(){ MasterAccountInfo msi = dataMethods.getMasterAccountInfo(); ObjectMapper mapper = new ObjectMapper(); try { return mapper.writeValueAsString(msi); } catch (JsonProcessingException e) { // TODO Auto-generated catch block e.printStackTrace(); return "failed transform"; } } @RequestMapping(value="/setuserINN", method = RequestMethod.POST) public String setUserINN(@RequestParam("INN") String INN){ Principal pr = SecurityContextHolder.getContext().getAuthentication(); String str = pr.getName(); dataMethods.changeUserInfo(str, INN); return "redirect:/myaccount"; } }

StreamUtils was added in Spring 3.2.2. You'll need to upgrade to at least that version of Spring for it to work.

I don't know how ant was compiled WAR in local machine but

org.springframework.util.StreamUtils exist only in spring-core-4.0.jar I used 3.1.1 version without this package.

I am insert library v4.0 in WAR and all is work.

Upgrade your spring version to at least(4.2.1.RELEASE) or latest version for it to work.
