LazyInitialization / join fetch

I have a survey that carries the tabla Items . A company has several items , a user charge and technical user also .
A specialty has several technical users .

Area A has a charge .

What happens :

When I click the Items table hibernate does all these other queries without me asking .

This may be occurring due to not doing the fetch join?

If so should I do to all fields of List , ie OneToMany or should also be done for joins ?
Grateful.

Are you using Hibernate? This is the ObjectDB forum not the Hibernate forum.
