CAUTION! Using @Modifying(clearAutomatically=true) will drop any pending updates on the managed entities in the persistence context spring states the following : Doing so triggers the query annotated to the method as an updating query instead of selecting one. As the EntityManager might contain outdated entities after the execution of the modifying query, we do not automatically clear it (see ...
Yes you need @Transactional when modifying data even with @Modifying that is only an annotation to let Spring Data know you have a @Query that changes stuff. The @Transactional marks the start AND end of a transaction. If you put it in your service layer everything called from within a single method participates in the same transaction.

If so, could you explain how should I use properly (any annotation for proper usage)? 2. I am also wondering if the similar issue is valid for @Transactional annotation?
I'd like to modify the path to my application, but doing so breaks it because the service still points to the old location. By going to Administrative Tools > Services you can open a properties
Error: ORA-12838: cannot read/modify an object after modifying it in parallel. Committing the delete defeats the purpose of course. Is there a way I can use an uncommited delete followed by an insert
