In Spring Data JPA, what is the primary role of the @Transactional annotation?
- To configure caching mechanisms.
- To define database schemas.
- To manage database transactions.
- To specify query parameters.
The primary role of the @Transactional annotation in Spring Data JPA is to manage database transactions. It marks a method, class, or even an interface to indicate that a transaction should be created and managed around the annotated method or methods. This ensures data consistency by committing changes if everything succeeds or rolling back if an exception occurs during the annotated operation. It is essential for maintaining data integrity in a Spring Data JPA application.
