How is context management carried out in Spring Boot applications?

In Spring Boot, application context management is carried out through the Spring ApplicationContext — a container that manages the lifecycle of beans and their dependencies.

Main ways to manage the context:

• Automatic component scanning (@ComponentScan) — Spring automatically finds and registers beans.
• Configuration via @Configuration and @Bean — explicit declaration of beans and their dependencies.
• Profiles (@Profile) — allow activating different configurations depending on the environment.
• Using ApplicationContext to programmatically obtain beans — for example, through injecting ApplicationContext and calling getBean().

Example of obtaining a bean from the context:

@Autowired
private ApplicationContext context;

public void example() {
    MyService service = context.getBean(MyService.class);
    service.doWork();
}
