That is the most significant change that. Now, the 3.0 version marks the migration from Java Persistence to Jakarta Persistence, so, for this reason, you will have to replace the javax.persistence package imports with the jakarta.persistence namespace. Therefore, the Querydsl dependency has to use jakarta classifier instead of the old jpa classifier (see this reference). By default, Spring 6 uses Hibernate 6.1, which in turn uses Jakarta Persistence 3.1. The dependencies have to be used from Jakarta instead of Javax. Each Hibernate project releases new versions independently and picks the version of its dependencies according to its needs and compatibility requirements. There is no 'release train' in Hibernate projects. The Querydsl version was not changed, but it was impacted in a similar way as the Liquibase. Hibernate projects with the same version number are not automatically compatible. Note: the previously used version (in our case) was the 2.7.5 version. Switch Jakarta baseline to Jakarta EE 10 and.The Spring Boot 3.0.2 depends on Spring Data Release Train 2022.0.1 (see Spring Data 2022.0 - Turing Release Notes), where Spring Data JPA 3.0.1 is used with these key changes (see the release notes): The Hibernate Jpamodelgen maven dependency managed by Spring Boot Dependencies was moved from org.hibernate to package. The Hibernate 6 returns the deduplicated result now. The changed behavior is caused by the new Semantic Query Model with Automatic deduplication (see Semantic Query Model part) introduced with the Hibernate 6 (see line 178 in .spi.ListResultsConsumer class). However, the test receives only a single entity from the Hibernate, as you can see in these debugging screenshots: Hibernate: select c2_0.id,c2_0.name from city c1_0 join country c2_0 on c2_0.id=c1_0.country_id where c1_0.name like ? escape '!' and c1_0.state like ? escape '!'

Spring MVC 6.0.4Īll methods in the ResponseEntityExceptionHandler class changed their signatures. Switch Jakarta baseline to Jakarta EE 9+.īesides that, there's just one minor change in Spring MVC used in SAT project.Switch Java baseline to Java 17 (still the last Java LTS at the time of writing this article) - i.e., it's a minimum Java version we have to use.Spring Framework 6 has many changes (see What's New in Spring Framework 6.x), the key changes are: The goal of this article is to highlight these changes when upgrading the sat-jpa project (SAT project). This release is based on Spring Framework 6 with several significant changes and issues which we should consider when upgrading. Since the end of last year, there's been a new major release of Spring Boot 3. Last year, I wrote two articles about JPA Criteria and Querydsl (see Introduction and Metamodel articles).
