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"; 

奏效。
