implementing Hibernate's lazy loading in a bidirectional one-to-many relationship with Java 17
I'm integrating two systems and I'm currently working with a question with Hibernate's lazy loading in a bidirectional one-to-many relationship between two entities, `User` and `Post`... The `User` object has a collection of `Post` objects that are lazily loaded. When I try to access the list of posts after the session has been closed, I encounter a `LazyInitializationException`. Here's the code structure I have: ```java @Entity public class User { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; @OneToMany(mappedBy = "user", fetch = FetchType.LAZY) private List<Post> posts; // getters and setters } @Entity public class Post { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) private Long id; @ManyToOne @JoinColumn(name = "user_id") private User user; // getters and setters } ``` In my service method, I fetch the `User` entity like this: ```java User user = userRepository.findById(userId).orElseThrow(); List<Post> posts = user.getPosts(); // This is where the LazyInitializationException occurs ``` I've tried using `Hibernate.initialize(user.getPosts())` before closing the session, but it didn't work as expected. I also considered changing the fetch type to `EAGER`, but I'm concerned about potential performance optimization and fetching too much data at once, especially if a user has many posts. What are the best practices for handling this scenario? Should I stick with lazy loading or is there a more effective way to fetch the posts while avoiding this exception? What would be the recommended way to handle this?
