Java 17: Difficulty with JPA Entity Lifecycle Callbacks Not Triggering on Cascade Persist
This might be a silly question, but Hey everyone, I'm running into an issue that's driving me crazy. I'm facing an issue where my JPA entity lifecycle callbacks, specifically `@PrePersist` and `@PostPersist`, are not being triggered for child entities when I use cascade persist. I have a `Parent` entity that has a one-to-many relationship with a `Child` entity. I've annotated the methods in my `Child` entity to log when they are called, but they never seem to execute during a cascade persist operation. Here's the relevant code: ```java @Entity public class Parent { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; @OneToMany(mappedBy = "parent", cascade = CascadeType.PERSIST) private List<Child> children = new ArrayList<>(); public void addChild(Child child) { children.add(child); child.setParent(this); } } @Entity public class Child { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; @ManyToOne private Parent parent; @PrePersist private void prePersist() { System.out.println("Child is about to be persisted: " + this); } @PostPersist private void postPersist() { System.out.println("Child has been persisted: " + this); } } ``` When I try to persist a `Parent` entity with children like this: ```java Parent parent = new Parent(); Child child1 = new Child(); Child child2 = new Child(); parent.addChild(child1); parent.addChild(child2); entityManager.persist(parent); ``` I see the parent being persisted without any logs from the `Child` entity. I've confirmed that the `Child` objects are being added to the `Parent`'s collection correctly. I've also checked that the EntityManager is being used within a transaction. Is there something obvious that I'm missing, or is there a specific configuration that I need to be aware of in order for these callbacks to work with cascading persists? Any guidance would be greatly appreciated! I'm using Hibernate 5.5.7.Final and Spring Boot 2.5.4. This is part of a larger web app I'm building. Is there a better approach? How would you solve this?
