What processes are initiated when launching an application that uses the Spring Framework?

When launching an application on the Spring Framework, several key processes occur:

1. ApplicationContext Initialization — Spring creates and configures the container that manages the lifecycle of beans.

2. Component Scanning — the framework scans specified packages for annotations (@Component, @Service, @Repository, etc.) and registers the corresponding beans.

3. Dependency Injection — Spring automatically wires beans together, injecting necessary dependencies.

4. Initialization Methods Execution — if beans implement the InitializingBean interface or have methods annotated with @PostConstruct, they are invoked.

5. Starting the embedded server (if it is a Spring Boot application) — for example, Tomcat or another servlet container is started.

6. Application readiness to handle requests — after full initialization, the application begins accepting and processing incoming requests.

Thus, Spring provides automatic management of components and their relationships, simplifying development and maintenance of applications.
