What is the significance of the @Transactional annotation in Spring Data JPA?
- It indicates that the entity is transactional, allowing it to participate in database transactions.
- It specifies the transaction isolation level for the JPA entity.
- It triggers a rollback of the current transaction if an exception is thrown within the annotated method.
- It controls the caching behavior of JPA entities.
The @Transactional annotation in Spring Data JPA is significant because it ensures that if an exception is thrown within the annotated method, the current transaction will be rolled back. This is crucial for maintaining data consistency and integrity. While the other options may have some relevance in JPA, they do not directly represent the primary significance of @Transactional in this context.
