Configuring HttpSecurity

Before

@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests((authz) -> authz
                .anyRequest().authenticated()
            )
            .httpBasic(withDefaults());
    }

}

After

@Configuration
public class SecurityConfiguration {

    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests((authz) -> authz
                .anyRequest().authenticated()
