when the insertPerson method of PersonRepository is call,no Data is inserted into dataBase
in other world the #Transactional not work

Answer 1

Are you creating Person while setting the id? If so, it might be the problem, as hibernate thinks the object already exists and tries to update instead of insert. Try using a sequence and let hibernate set the id.
