Hi! My name is Inácio and I took a look at your issue and want to help clarify a few common causes of this error during migration from Spring Boot 2.7.x to 3.3.x.
I've come across these errors a few times and after some research some important points I noticed that we should pay attention to after migrating from such different versions of SpringBoot are as follows:
 Compatibility:
First of all, you have to pay attention on compatibilities, make sure that all dependencies are compatible with your actual version of Spring.
 Missing “jakarta.persistence” annotations:
Ensure that all your entity classes are using “jakarta.persistence.” imports, not “javax.persistence.”. Spring Boot 3 uses Jakarta EE 9+ and requires this change.
 Incorrect or missing “EntityManagerFactory” bean:
If you're using custom JPA configurations or have a non-standard setup, make sure that Spring Boot is able to auto-configure the “EntityManagerFactory”. You might need to explicitly define “@EnableJpaRepositories” and “@EntityScan”.
 Incomplete Spring Security configuration:
If you recently updated Spring Security, double-check your “SecurityFilterChain” bean and ensure that any authenticationManager or authorization configs are updated to the Spring Security 6+ style.
 Missing or outdated JPA dependencies:
If you're using Hibernate, make sure you're depending on “hibernate-core:6.x” versions compatible with Spring Boot 3.
