Страница входа в Spring Security и регистрация пользователя в одном файле html

Question

Я немного новичок в Spring и в настоящее время пытаюсь создать веб-приложение, которое включает вход в систему пользователя с защитой весенней загрузки. Первоначальная аутентификация при входе в систему работала, когда у меня была страница входа в систему и я создал страницу пользователя в виде двух отдельных HTML файлов. Сейчас я пытаюсь создать одну веб-страницу, используя javascript. Однако я больше не могу получить доступ к страницам.

Это мой пользователь Entity

package com.fncd.model;

import java.util.Collection;

@Entity

public class Users {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long user_id;
    private String first_name;
    private String last_name;
    private String email;
    private String password;

    @OneToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
    @JoinTable(
            name = "users_roles",
            joinColumns = @JoinColumn(
                    name = "user_id", referencedColumnName = "user_id"),
            inverseJoinColumns = @JoinColumn(
                    name = "role_id", referencedColumnName = "id"))
    private Collection<Role> roles;

    public Users() {
    }

    public Users(String first_name, String last_name, String email, String password) {
        this.first_name = first_name;
        this.last_name = last_name;
        this.email = email;

    }

    public Users(String first_name, String last_name, String email, String password,
            Collection<Role> roles) {
        this.first_name = first_name;
        this.last_name = last_name;
        this.email = email;
        this.password = password;
        this.roles = roles;
    }

    @Override
    public String toString() {
        return "Users {" + 
               "user_id=" + user_id +

    }

    public Collection<Role> getRoles() {
        return roles;
    }

    public void setRoles(Collection<Role> roles) {
        this.roles = roles;
    }

    public Long getUser_id() {
        return user_id;
    }

    public void setUser_id(Long user_id) {
        this.user_id = user_id;
    }

    public String getFirst_name() {
        return first_name;
    }


    public void setFirst_name(String first_name) {
        this.first_name = first_name;
    }

    public String getLast_name() {
        return last_name;
    }

    public void setLast_name(String last_name) {
        this.last_name = last_name;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

}

                .permitAll().anyRequest().authenticated().and().formLogin().loginPage("/login").defaultSuccessUrl("/dashboard", true).permitAll().and().logout()
                .invalidateHttpSession(true).clearAuthentication(true)
                .logoutRequestMatcher(new AntPathRequestMatcher("/logout")).logoutSuccessUrl("/login?logout")
                .permitAll();
    }

    @Bean
    public BCryptPasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Bean
    public DaoAuthenticationProvider authenticationProvider() {
        DaoAuthenticationProvider auth = new DaoAuthenticationProvider();
        auth.setUserDetailsService(userService);
        auth.setPasswordEncoder(passwordEncoder());
        return auth;
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(authenticationProvider());
    }

}
