/**
* {@link ConfigurableReactiveWebApplicationContext} that accepts annotated classes as
* input - in particular {@link Configuration @Configuration}-annotated classes, but also
* plain {@link Component @Component} classes and JSR-330 compliant classes using
* {@code javax.inject} annotations. Allows for registering classes one by one (specifying
* class names as config location) as well as for classpath scanning (specifying base
* packages as config location).
*
* Note: In case of multiple {@code @Configuration} classes, later {@code @Bean}
* definitions will override ones defined in earlier loaded files. This can be leveraged
* to deliberately override certain bean definitions via an extra Configuration class.
