jakarta.persistence.TransactionRequiredException: Executing an update/delete query

I use spring boot 3.0.0, I try to use query.executeUpdate() method .

There is my code:

@Transactional
public void UpdatePassageByNiveau(int niveau, String cin) {
    String queryRecherche = "UPDATE Passage p SET p.dateDebut = p.dateDebut + 1 year, "
            + "p.dateFin = p.dateFin + 1 year WHERE resident.cin = :cin and p.niveau = :niveau ";
    Query query = em.createQuery(queryRecherche);
    query.setParameter("cin", cin);
    query.setParameter("niveau", niveau);
    query.executeUpdate();
}

I use the annotation @Transactional from org.springframework.transaction.annotation.Transactional. But it didn’t work, and i steal have this error : jakarta.persistence.TransactionRequiredException: Executing an update/delete query|.

>Solution :

This error typically occurs when we’re trying to perform a database operation that modifies the database without a transaction.

The obvious solution is to wrap any database-modifying operation in a transaction:

Transaction txn = session.beginTransaction();
Query query
  = session.createQuery("UPDATE Passage p SET p.dateDebut = p.dateDebut + 1 year, "
            + "p.dateFin = p.dateFin + 1 year WHERE resident.cin = :cin and p.niveau = :niveau ");
    query.setParameter("cin", cin);
    query.setParameter("niveau", niveau);
updateQuery.executeUpdate();
txn.commit();

In the code snippet above, we manually initiate and commit the transaction. Although in a Spring Boot environment, we can achieve this by using the @Transactional annotation.

@Service
@Transactional
public class FooService {
    //...
}
