Answer
Semantic roles and exception translation. Frame the concept in practical terms so you can explain it during interview discussion.
@Repository and @Service are specialized annotations extending @Component. @Repository is used for data access layers and supports exception translation, converting database exceptions into Spring's DataAccessException. @Service indicates a business logic layer, aiding in readability and organization. For example, a UserRepository might be marked with @Repository for database operations, while UserService would be marked with @Service for business logic.
