Spring 6: HibernateTemplate Bean creation fails with java.lang.NoClassDefFoundError: org/hibernate/criterion/DetachedCriteria

[damodarp]

When using Spring 6 with Hibernate 6, HibernateTemplate bean creation fails with the following error.

This is because HibernateTemplate still has references to org.hibernate.criterion package classes which are deleted in Hibernate 6.

Why do we still have references to these removed hibernate classes?

Can this be fixed?

The HibernateTemplate class lives in the hibernate5 template and is not compatible with Hibernate 6. In fact, most operations there have been deprecated in #20972.

The preferred solutions are described in the Javadoc of this class. Those warnings applied to the Hibernate 5.x generation and applications are expected to not use this class with Hibernate 6.x.
