Modify persistent JPA object
I have an entity student with details, how do l allow an update of existing data and keep track of changes made on the object?
Student oldStudent = new Student()
oldStudent.getStudent(id);
Copy contents of old student, and save them on an amendment entity
Then update the oldstudent and save it as the new referenced entity.
Help will be appreciated on how to go about this using jpa.
spring-boot jpa spring-data-jpa

Can use a apache library for copying:
http://commons.apache.org/proper/commons-beanutils/
copyProperties(Object o1, Object o2)
this will copy all fields from current object to update object..
