What is Spring Transactional?

Spring Transactional provides declarative transaction management using annotations or XML configuration in Spring applications. It simplifies transaction handling by abstracting away the complexities of underlying transaction APIs (like JDBC or JPA). The `@Transactional` annotation is commonly used to demarcate methods or classes as transactional, ensuring atomicity, consistency, isolation, and durability (ACID) for database operations within those methods or classes. It automatically manages transaction boundaries, committing changes on success and rolling back on exceptions, greatly reducing boilerplate code for transaction management.
