Answer

The actual error is:

Caused by: org.springframework.data.mapping.PropertyReferenceException: No property id found for type Department!

JavaScript
 
Caused by: org.springframework.data.mapping.PropertyReferenceException: No property id found for type Department!​

Your repository method:

Department findDepartmentById(Long departmentId);

JavaScript
 
Department findDepartmentById(Long departmentId);​

But you dont have id property in your Department entity. You have departmentId. So try renaming your method to something like:

Department findByDepartmentId(Long departmentId);

JavaScript
 
Department findByDepartmentId(Long departmentId);​
