Cascade-Generated ORM Code Causes LazyInitializationException
Hibernate throws LazyInitializationException when accessing related entities that Cascade marked as lazy-loaded. The session closes before the related data is fetched, causing 'no Session' errors at runtime.
Cascade refactored entity relationships without considering transaction boundaries or fetch strategy.
Error Messages You Might See
org.hibernate.LazyInitializationException: could not initialize proxy - no Session
Failed to lazily initialize a collection
detached entity passed to persist
Common Causes
- Cascade set FetchType.LAZY on relationships without using @Transactional properly
- DTO mapping happens outside transaction scope, trying to access lazy collections
- Cascade removed @Transactional from service methods that need it
- ViewExpander pattern not applied to eager load required relationships
How to Fix It
Wrap data access in @Transactional methods to keep session open. Use FetchType.EAGER for frequently accessed relationships. Implement custom fetch strategies with JPQL or HQL join fetch. Consider using DTOs with specific fetch patterns instead of loading entire entities.

When does this error occur?
When code accesses lazy-loaded relationship after transaction/session closes, typically in view layer or after method returns.
What's the best fix?
Use @Transactional on service methods and eager load required relationships with join fetch in queries.
