    private UserDetailsService userDetailsService;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .formLogin()
                .loginPage("/login")
                .failureUrl("/login?error")
                .usernameParameter("email")
                .permitAll()
                .and()
                .logout()
                .logoutUrl("/logout")
                .logoutSuccessUrl("/")
                .permitAll();
    }

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .userDetailsService(userDetailsService)
                .passwordEncoder(new BCryptPasswordEncoder());
    }
}

the dependency for it is:
