Como criar o método AuthenticationManagerBuilder com o Spring 2.7 ?

Não consigo fazer @Override no configure(AuthenticationManagerBuilder auth) na versão 2.7.2 do Spring (acredito que tenho que injetar alguma dependência, @BEAN). Alguém consegue me ajudar?

(package e imports omitidos)

@Configuration @EnableWebSecurity public class WebSecurityConfig {

@Autowired
private DataSource dataSource;

@Bean
public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
    http
        .authorizeRequests()
            .anyRequest().authenticated()
        .and()
        .formLogin(form -> form
            .loginPage("/login")
            .defaultSuccessUrl("/home", true)
            .permitAll()
        )
        .logout(logout -> logout.logoutUrl("/logout"));
    return http.build();

}

protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();       // encoder para criptografar os dados

     User.builder()
        .username("joao")
        .password(encoder.encode("joao"))
        .roles("ADM")
        .build();

    auth.jdbcAuthentication()
        .dataSource(dataSource)
        .passwordEncoder(encoder);
}

}

@Configuration @EnableWebSecurity public class WebSecurityConfig{ @Autowired private DataSource dataSource; @Bean public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception{ http .authorizeHttpRequests() .anyRequest().authenticated() .and() .formLogin(form -> form .loginPage("/login") .defaultSuccessUrl("/home",true) .permitAll()) .logout(logout -> logout.logoutUrl("/logout")); return http.build(); } @Bean public PasswordEncoder passwordEncoder(){ return new BCryptPasswordEncoder(); } @Bean public JdbcUserDetailsManager users(PasswordEncoder encoder){ UserDetails user = User.builder() .username("joao") .password(encoder.encode("joao")) .roles("ADM") .build(); JdbcUserDetailsManager jdbcUserDetailsManager = new JdbcUserDetailsManager(dataSource); jdbcUserDetailsManager.createUser(user); return jdbcUserDetailsManager; } }
