Answer 1

可以这样做：

@Autowired
private MyOtherController otherController;

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

您永远不必将业务逻辑放入控制器,并且与数据库相关的业务逻辑较少,事务类/方法应该在服务层中.但是,如果您需要重定向到另一个控制器方法,请使用重定向

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