Is it possible to apply additional Bean components during the execution of a method marked with PostConstruct in Spring?

In a method annotated with @PostConstruct in Spring, you can use already created and injected Bean components, but creating new Bean components dynamically at this moment is not recommended and is not standard practice.

The @PostConstruct annotation indicates a method that is called after Spring has completed dependency injection into the Bean, but before the Bean is available for use. At this stage, the context is already initialized, and you can access other Bean components, but adding new Bean components to the context during @PostConstruct execution is not provided for.

If you need to dynamically create or register Bean components during runtime, it is better to use other mechanisms, such as BeanFactory or ApplicationContext with programmatic Bean registration, but not within @PostConstruct methods.
