Spring Boot 3 with Hibernate ORM 6.2.0

IzabellaK · April 13, 2023, 10:49am

I upgraded my Spring Boot Application to version 3.0.2 and use Hibernate ORM 6.1.7.Final
Due to issues with “fetch” I wanted to try using ORM 6.2.0.Final to check if in this version our problems will go away but I even couldn’t start the app. I’m getting:

java.lang.ClassCastException:
class org.hibernate.mapping.BasicValue cannot be cast to class org.hibernate.mapping.ToOne (org.hibernate.mapping.BasicValue and org.hibernate.mapping.ToOne are in unnamed module of loader ‘app’)

and it complains about Hibernate Configuration class.

do I need to add any additional dependencies to my pom to be able to use it ?
right now I have :

org.springframework.boot spring-boot-starter-parent 3.0.2 6.2.0.Final org.hibernate.orm hibernate-spatial ${hibernate.version} org.hibernate.orm hibernate-graalvm ${hibernate.version}

I checked: despite I didn’t specify

org.hibernate.orm hibernate-core ${hibernate.version}

the version for it was 6.2.0

Hello, this error looks very similar to [HHH-16437] - Hibernate JIRA, but without the full stack trace and the mapping that causes the problem I can’t be sure.

Please check my comment and that issue and verify if you’re using mappedBy correctly in your associations.

IzabellaK · April 13, 2023, 8:52pm

Thank you for your response. I don’t use “id.fieldName” in mappedBy, just the normal field names.

mbladel · April 14, 2023, 7:15am

The field name itself is not the problem, is the type of the field referenced with mappedBy which has to be an Entity type to correctly define a bi-directional association, not a basic type (like Integer or id).

As I said, without seeing your mappings it’s hard to say. I suggest you to read through the issue I linked, including the reference to the User Guide which explains this in more detail.

Hello,

i made an example to reproduce: GitHub - mosesonline/jpa-error
Simply replace spring-boot versoin to 3.1.0 and the test breaks.

I don’t find anything in release notes or migration guides about this breaking change.

Hibernate Version 6.2.2 and 6.2.3.

Regards

Please post the error that you get. The problem sounds similar to [HHH-16593] - Hibernate JIRA though.

Yeah, you are running into [HHH-16593] - Hibernate JIRA

You can watch that issue to get updates about the topic. In the meantime, you can model this with @MapsId on the @OneToOne

I ran into this too. At first I generated some entities using the IDE. Everything was okay but then I made some changes to the schema (added foreign key constraints). This is where into the error. Regenerating the entities is what I did.
