Should i use @transactional on my @repository class or is it only needed in my service class when i need to rollback write transactions? So even though i use a hikari pool using a repository class should deal with proper closing connections? So @transactio

The @Transactional annotation in Spring Hibernate with HikariPool is used to manage transactions in the database. It ensures that a group of operations are treated as a single unit of work, either committing all changes or rolling back if an error occurs.

It is generally recommended to use the @Transactional annotation on service classes rather than repository classes. This is because service classes typically contain business logic and orchestrate multiple database operations, making them the ideal place to manage transactions.

When using @Transactional, ensure that you set the propagation and isolation levels correctly based on your requirements. Propagation defines how nested transactions should behave, while isolation determines how concurrent transactions interact with each other.

Remember that the @Transactional annotation should be used sparingly and only when necessary, as it adds overhead to your application. Avoid annotating every method with @Transactional unless they truly require transaction management.

In summary, use @Transactional on your service classes to manage transactions effectively in Spring Hibernate with HikariPool. Ensure proper configuration of propagation and isolation levels to maintain data integrity and consistency.
