How spring boot works , what is beans and scope of the beans

Question

Accepted Answer

Spring Boot is a framework that simplifies the development of Java applications by providing pre-configured settings and dependencies.

Spring Boot uses the concept of 'beans' to manage application components and their dependencies.
Beans are Java objects that are instantiated, assembled, and managed by the Spring IoC container.
The scope of a bean determines its lifecycle and visibility within the application context.
There are several bean scopes in Spring Boot, including singleton, prototype, request, session, and global session.
Singleton beans are created once and shared throughout the application, while prototype beans are created each time they are requested.
Request and session beans are specific to a particular HTTP request or user session, respectively.
Global session beans are similar to session beans, but are shared across multiple user sessions.
Spring Boot also provides annotations and configuration options for customizing bean creation and management.
