推荐答案

您永远不必将业务逻辑放入控制器中,并且与数据库相关的业务逻辑更少,事务类/方法应该在服务层中.但是,如果您需要重定向到其他控制器方法,请使用redirect

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";
}
