Multiple WebSecurityConfigurerAdapter in spring boot for multiple patterns

To use multiple WebsecurityConfigurerAdapter, you need restrict them to specific URL patterns using RequestMatcher.

In your case you can set a higher priority for ActuatorSecurityConfig and limit it only to actuator endpoints:

@Order(-1)
@Configuration
public class ActuatorSecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .requestMatchers().antMatchers("/actuator/**")
                .and()
                .authorizeRequests().anyRequest().hasRole("ADMIN")
                .and()
                .httpBasic();
    }
}
