What is the impact of using the @Service annotation on a class over just using the @Component annotation in terms of functionality and semantics?
- Adds security features to the class, making it suitable for authentication purposes.
- Allows the class to be used as a database entity.
- Enhances the class's visibility in the Spring container but has no effect on functionality.
- Provides a way to define the class as a bean with additional metadata for business logic.
The @Service annotation in Spring is used to define a class as a service bean, typically used for business logic. It has the same functionality as @Component but adds semantic value, indicating that the class is a service component. While @Component is a generic stereotype, @Service is specific to services, making the code more expressive and helping developers understand the role of the class. It doesn't provide security features or make the class a database entity.
