The answer by @Sven is correct. Although, more resources / links can be referenced to get an overall idea about the reasoning.

Follow these steps to get Hibernate running with Spring 6.x (I used 6.2):

1. Although one might be able to work with other Hibernate versions, it is recommended to use Hibernate >= 5.16. Refer the Spring ORM documentation for details.
2. Use following dependencies in pom.xml:

   <dependency>
       <groupId>org.hibernate</groupId>
       <artifactId>hibernate-core-jakarta</artifactId>
       <version>5.6.15.Final</version>
   </dependency>
   <dependency>
       <groupId>jakarta.persistence</groupId>
       <artifactId>jakarta.persistence-api</artifactId>
       <version>3.0.0</version>
   </dependency>
   <dependency>
       <groupId>jakarta.transaction</groupId>
       <artifactId>jakarta.transaction-api</artifactId>
       <version>2.0.1</version>
   </dependency>
   

   Note: Hibernate 5.16 can only work in the jakarta namespace. That is why a different artifact hibernate-core-jakarta is used instead of the usual hibernate-core to make it work with Spring 6.x. For details, refer to the following links:
