用户注册并登录后，打开以下页面： https://myApp.by/assets/inputmask/jquery.inputmask.min.js
为什么第一次登录时不是到主页而是到 /assets/inputmask/jquery.inputmask.min.js
据我了解，此页面仅打开一次。我真的很想了解到底发生了什么，以免将来遇到问题。
我最后一次查看注册表已经是两个多月前了..所以我不能说问题是什么时候出现的。

和控制器
@Controller
public class LoginController {
@Autowired
UserRepository userRepository;
@RequestMapping("/login")
public String login() {
return "login";
}
@RequestMapping("/")
public String index(Locale locale, Model model, RedirectAttributes attrs) {
model.addAttribute("locale", locale);
Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();
String username;
if (principal instanceof UserDetails) {
username = ((UserDetails)principal).getUsername();
} else {
username = principal.toString();
}
User loginedUser = userRepository.findByLogin(username);
System.out.println("User logined" + loginedUser.toString());
if(loginedUser.isBanned()) {
return "redirect:/welcomeBanned";
}
if(SecurityContextHolder.getContext().getAuthentication().getAuthorities().contains(Role.DEFAULT)) {
return "redirect:/welcome";
}
if(SecurityContextHolder.getContext().getAuthentication().getAuthorities().contains(Role.USER)) {
return "redirect:/index";
}
if(loginedUser.getRoles().isEmpty()) {
return "redirect:/welcome";
}
return null;
}
我认为问题可能出在你的 if 语句中。尝试使用重定向编辑 if null 语句，以便将它们发送到主页等位置。如果不满足任何条件，这应该会停止程序将用户发送到随机 URL。
所以而不是
return null;
有（或选择您想发送到的地方）
return "redirect:/login";
