Hibernate not populating lazy-loaded collections in @OneToMany relationship after transaction commit
After trying multiple solutions online, I still can't figure this out. I'm working on a personal project and I'm relatively new to this, so bear with me. I'm facing an issue where a lazy-loaded collection in an `@OneToMany` relationship is not being populated after I commit the transaction in Hibernate. I'm using Hibernate 5.4.32 alongside Spring Boot 2.5.4. The parent entity is supposed to fetch its child entities only when accessed, but I'm getting an empty collection despite having the correct data in the database. Here’s a simplified version of my entities: ```java @Entity public class Parent { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; @OneToMany(mappedBy = "parent", fetch = FetchType.LAZY) private Set<Child> children = new HashSet<>(); // getters and setters } @Entity public class Child { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; @ManyToOne @JoinColumn(name = "parent_id") private Parent parent; // getters and setters } ``` I retrieve the `Parent` entity in a service method like this: ```java @Transactional public Parent getParent(Long parentId) { Parent parent = parentRepository.findById(parentId).orElse(null); // transaction will be committed here return parent; } ``` After the transaction is committed, when I try to access `parent.getChildren()`, I'm getting an empty set. I’ve also verified that the children exist in the database with the correct `parent_id`. I tried enabling the logging for Hibernate SQL and confirmed that no additional SELECT statement is executed when accessing the children after the commit. I also played around with the transaction propagation settings by trying `REQUIRES_NEW`, but it didn’t help. Am I missing something in my Hibernate configuration, or is there a specific reason why the lazy loading isn't happening after the transaction is committed? Any insights would be appreciated. For context: I'm using Java on Windows. Any ideas what could be causing this? For context: I'm using Java on Windows. Thanks in advance!
