控制器

@RequestMapping(value="/register", method= RequestMethod.GET)
public String register(ModelMap modelMap){
    modelMap.put("user", new User());
    return "account/register";
}


@RequestMapping(value="/register", method= RequestMethod.POST)
public String register(@ModelAttribute("user") User user){
    BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder();
    user.setPassword(bCryptPasswordEncoder.encode(user.getPassword()));
    userService.register(user);

    return "redirect:../login";
}

在UserDAOImpl

@Override
public void register(User user) {

    mongoTemplate.insert(user);
}

UserServiceImpl

@Override
public void register(User user) {
     userDao.register(user);
}

Answer 1

替换

return "redirect:../login";

要

return "redirect:/login";

的工作。
