What is the role of the @Service annotation in a Spring project and how does it affect the application's componentization?

The @Service annotation in Spring is used to designate a class as a service component that contains the application's business logic.

Role of @Service:

• Marks the class as a Spring Bean, which will be automatically detected and registered in the application context (via component scanning).
• Helps separate application layers, highlighting the service layer apart from controllers and repositories.
• Improves code readability and maintainability by explicitly indicating that the class is responsible for business logic.

Impact on component architecture:

Using @Service promotes a modular architecture where business logic is encapsulated in separate components, facilitating testing, reuse, and maintenance of the code.
