How to Solve org.hibernate.LazyInitializationException in Hibernate?

Troubleshooting org.hibernate.LazyInitializationException in Hibernate ORM

The org.hibernate.LazyInitializationException occurs when an attempt is made to access a lazily initialized field outside of an active Hibernate session. This exception is commonly encountered when working with Hibernate entities that have been retrieved from the database but are not fully initialized in the current session.

One of the possible solutions to this exception is to ensure that the session is active when accessing the lazily initialized field. To achieve this, you can add @Transactional annotation to the methods that need to access the lazily initialized fields.

By annotating the method with @Transactional, Spring handles the session management automatically. When another transactional method is called, it can join the ongoing transaction, preventing the "no session" exception. However, it's crucial to be aware of the resulting behavior when using @Transactional. Updates to entities are automatically persisted, even without explicitly calling the save() method.
