Question

: Hibernate/Spring: how to solve the problem failed to lazily initialize - no session or session was closed

Answer 1

You try to access some lazy field (usually collection) in entity which is in detached state.
You can try to use FetchType.EAGER in relation annotation. Or just access this field while session is not closed.

Answer 2

Thank you for your idea. Any idea if we don't want to use FetchType.EAGER ?
