What is the @Transactional annotation in Spring Boot?

What is the @Transactional annotation in Spring Boot?

The @Transactional annotation in Spring Boot is used to manage transactions in your application. It ensures that a series of operations either complete successfully or fail together, maintaining data integrity.

How do I use the @Transactional annotation in my service class?

You can use the @Transactional annotation by placing it above your service method. For example:

@Transactional
public void myServiceMethod() {
    // your code here
}

Can I use @Transactional on a class level?

Yes, you can apply @Transactional at the class level, which will make all public methods in that class transactional.

What happens if an exception occurs in a @Transactional method?

If an unchecked exception occurs, the transaction will be rolled back. However, for checked exceptions, you need to specify rollback rules.
