Java 17: implementing managing transaction boundaries using Spring Data JPA and Hibernate
I'm stuck trying to I'm experiencing unexpected behavior when trying to manage transaction boundaries in my Spring Boot application using Spring Data JPA and Hibernate... I have a method that should save an entity and a related collection of entities within a transaction, but sometimes it seems like the transaction isn't committing. Here’s the code snippet: ```java @Service public class MyService { @Autowired private MyRepository myRepository; @Transactional public void saveEntities(MyEntity entity, List<RelatedEntity> relatedEntities) { myRepository.save(entity); relatedEntities.forEach(re -> myRepository.save(re)); } } ``` In some cases, I notice that the `relatedEntities` are not being persisted, and I receive a `javax.persistence.EntityNotFoundException` when trying to access them later. I’ve tried using `@Transactional(propagation = Propagation.REQUIRES_NEW)` on the method to see if that changes anything, but it didn’t help. I also verified that the `MyEntity` and `RelatedEntity` are properly annotated with `@Entity` and that their relationships are set up correctly with `@OneToMany` and `@ManyToOne`. I’m using Spring Boot 2.5.4 and Hibernate 5.5.7.Final. Any insight into why the transaction might not be committing fully or what I might be missing in the setup would be greatly appreciated! For reference, this is a production CLI tool. How would you solve this?
