Javers.commit() not working MANAGED_CLASS_MAPPING_ERROR

Question

I am getting below error: and I am working with Spring Boot AOP Javers. Javers.commit() works fine in another class but in aspect class it gave me below error. i don't know if there is a special way to work with AOP and Javers at the same time.

my code is here : https://github.com/mohamedBenali100/JaversAOPIssue

org.javers.common.exception.JaversException: MANAGED_CLASS_MAPPING_ERROR: given javaClass 'class java.lang.Long' is mapped to PrimitiveType, expected ManagedType

Answer 1

I found the issue in my code or i shuld say a friend of mine who helped me to find it. So in my case there is 4 mistakes i did :

1_ in pom file i used : javers-core but i shuld use javers-spring as dependency

2_ In my service class i used : javax.transaction.Transactional but i shuld use org.springframework.transaction.annotation.Transactional and i shuld add .orElseThrow(EntityNotFoundException::new) to my functions to evoid exception when your object is not there.

3_ I had to add a configuration calss named JaversConfig with Bean javers.

4_ In my Aspect class i needed to use DI for javers and needed to use service instead of repository for searching for an object.

I don't know if i explainted that well but you will find my working code in this link: https://github.com/mohamedBenali100/JaversAOPIssue
