Spring Security Spring Boot +百里香叶：......无法显示错误，自动转换到登录页面

我有一个注册页面。字段数据经过验证。当用户注册的控制器方法中捕获到错误并再次调用注册页面时（应该显示错误），会自动重定向到**/login**URL。
org. apache. juli. logging. DirectJDKLog [错误] 19：34：25-路径为[]的上下文中的servlet [dispatcherServlet]的Servlet. service（）引发异常[请求处理失败：org.thymeleaf.exceptions.TemplateInputException:模板解析期间出错（模板："类路径资源[templates/account/register.html]"）]具有根本原因的java. lang.非法状态异常：Bean名称"userData"的BindingResult和普通目标对象均不可用作org.springframework.web.servlet.support.BindStatus（BindStatus.java：153）上的请求属性，位于org.springframework.web.servlet.support.RequestContext.getBindStatus（RequestContext.java：926）上

注册控制器

@Controller
@RequiredArgsConstructor
public class RegistrationController {

    private final UserService userService;

    @GetMapping("/register")
    public String showRegistrationForm(final Model model){
        UserDataDto user = new UserDataDto();

        model.addAttribute("userData", user);
        return "account/register";
    }

    @PostMapping("/register")
    public String userRegistration(final @Valid UserDataDto userData,
                                   final BindingResult bindingResult,
                                   final Model model){
        if(bindingResult.hasErrors()){

            model.addAttribute("errors", userData);
            return "account/register";
        }
        try {
            userService.register(userData);
        }catch (UserAlreadyExistException e){
            
            bindingResult.rejectValue(
                    "email",
                    "userData.email",
                    "An account already exists for this email."
            );
            model.addAttribute("formreg", userData);
            return "account/register";
        }
        return "redirect:/login";
    }
}

登录页面控制器

@Controller
public class LoginPageController {

    @GetMapping("/login-error")
    public String loginError(Model model) {
        model.addAttribute("loginError", true);
        return "login";
    }

    @GetMapping("login")
    public String getLogin(){
        return "account/login";
    }
}

数据输出

public class UserDataDto {

    @NotEmpty(message = "First name can not be empty")
    private String firstName;

    @NotEmpty(message = "Last name can not be empty")
    private String lastName;

    @NotEmpty(message = "Email can not be empty")
    @Email(message = "Please provide a valid email id")
    private String email;

    @NotEmpty(message = "Password can not be empty")
    private String password;

  ...
}

安全配置

@Configuration
public class SecurityConfiguration {

    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {

        return http
                .authorizeHttpRequests()
                .requestMatchers("/login", "/register").permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin()
                .loginPage("/login").permitAll()
                .defaultSuccessUrl("/home")
                .failureUrl("/login?error=true")
                .and()
                .build();
    }

    @Bean
    public PasswordEncoder bCryptPasswordEncoder() {
        return new BCryptPasswordEncoder();
    }
}

我试过了：

控制器

@GetMapping("/handleLoginErrors")
    ModelAndView handleErrors(ModelAndView modelAndView){
        
        modelAndView.setViewName("account/register");
        return modelAndView;

    }

组态

@Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {

        return http
                .authorizeHttpRequests()
                .requestMatchers("/login", "/register").permitAll()
                .requestMatchers("/account/**").hasRole("ADMIN")
                .anyRequest().authenticated()
                .and()
                .formLogin()
                .loginPage("/login").permitAll()
                .defaultSuccessUrl("/home")
                .failureUrl("/handleLoginErrors").permitAll()
                //.failureUrl("/login?error=true")/**/
                .and()
                .build();
    }

但是，关键是要将错误返回到注册页面，以便用户可以看到他在注册过程中犯了什么错误，也就是说，要将用户返回到注册表单，并在发现这些错误的字段前面指出错误。
谁知道如何显示错误？为什么会自动重定向到/login，而不是您指定的页面？
