Project architecture：spring, springMVC,hibernate
Project Architecture Upgrade:
- JDK 8 to JDK 17
- Spring 5.2 to Spring 6.1.5
- Hibernate 5.3 to Hibernate 6.2.25
- Tomcat 8 to Tomcat 10

This issue occurred after the architecture upgrade. Since the concept of modularity was introduced after JDK 9, is there a solution in Hibernate that can be compatible with this adjustment? Please provide the cause of the error mentioned above and suggest a solution. Thank you.
