Why my servicelaundry_id didn't insert on the table <Hibernate | Spring Boot>

I've created ManyToMany tables with extra column that's named reqserviceguest_details, then I've tested with filling on my jsp page form to insert the data. When the all data inserted, everything is fine except my servicelaundry_id. It's null and I have no idea why it happened.

Hibernate: LazyInitializationException: failed to lazily initialize a collection of role

Using Hibernate 3.6.0
I'm having a real hard time understanding hibernate. I keep running into this issue with lazy initialization exception.
I have an Event entity with a one-to-many relationship with RSVP. When a run a test get back a list of events it works. But when I'm making the call in my controller in order to return it as json, I run into this lazy init error.

Your RSVP collection is fetched lazily. (If you don't specify a fetch type, the default is lazy). You need to change it to eager if you are planning to access it after the Hibernate session is closed:

private Set<RSVP> rsvps = new HashSet<RSVP>();

You need to specify a property name, not a property type.
SELECT H.MetadataForHibernate FROM HasBooks as H
need to be corrected to
SELECT H.book FROM HasBooks H
And you need a join to check a book properties
SELECT book
FROM HasBooks H inner join H.book book
where book.title :=title

The query you have written is not valid Hibernate Query Language (HQL), check the documentation for hints, or you can always use a native query to get an Object[] list from the result set, keeping the query you already have.
