Why Hibernate is running Update instead of Delete

CascadeType.ALL (specifically CascadeType.REMOVE here) doesn't mean the children will be removed if removed from the collection. It means that every state transition of the parent is cascaded to his child. Children are only removed automatically when the parent is deleted.

So by deleting the DVLoanParticipants in the collection, you are not asking Hibernate to delete the entity. You are asking him to update the record to point to no Loans, which results in a SQL update with NULL in the foreign key.

You need to had @OneToMany(orphanRemoval=true) for Hibernate to remove a child when he is separated from his parents (it must be detached from all parents for it to work).

That's not directly possible but you can achieve that with Blaze-Persistence Entity Views.

I created the library to allow easy mapping between JPA models and custom interface or abstract class defined models, something like Spring Data Projections on steroids. The idea is that you define your target structure(domain model) the way you like and map attributes(getters) via JPQL expressions to the entity model.

A DTO model for your use case could look like the following with Blaze-Persistence Entity-Views:

Spring JPA Add Additional Entries To Child Table

Asked 2021-Mar-27 at 15:26

This feels like something where there will already be answers to this, but I've looked through all manner of posts and am still struggling.

I'm learning how to use JPA with Spring Boot, and am specifically working to understand One To Many relationships. The issue at hand is I have a Customer Entity, and the Customer might have multiple email addresses associated with them, so we can contact multiple people at the customer. This gives me these models:

ANSWER

Answered 2021-Mar-27 at 15:26

To add new EmailAddress entity to your Customer entity you can simply call findById, or other find spring-data method and then create a new EmailAddress instance to append on that EmailAddress Collection on Customer entity. It would be nice if you post here some stacktrace exception, with that we can help a lot more!

PersistentBag uses Object's equals method for equals() and hashCode() Bug.

FIX:
Exclude students field for equals check by adding @EqualsAndHashCode.Exclude over it.
Now assert the Students values: assertThat(actual.get().getStudents()).containsOnlyElementsOf(expectedGroups.get(1).getStudents())

The first line of the stack trace is

What happens if you run this against your database outside of spring (i.e. directly from a db client)?
