Answer 1

Can do like this:

@Autowired
private MyOtherController otherController;

@RequestMapping(value = "/...", method = ...)
@ResponseBody
public String post(@PathVariable String userId, HttpServletRequest request) {
    return otherController.post(userId, request);
}

You never have to put business logic into the controller, and less business logic related with database, the transactionals class/methods should be in the service layer. But if you need to redirect to another controller method use redirect

@RequestMapping(value="/updatePSWD")
@ResponseBody
public String updatePswd()
{
  return "redirect:/getUser.do";
}
