You need not to worry about begin and end transaction. You have already apply @Transactional annotation, which internally open transaction when your method starts and ends when your method ends. So only required this is to persist your object in database.

 @Transactional(readOnly = false, isolation = Isolation.DEFAULT, propagation = Propagation.REQUIRED, rollbackFor = {Exception.class})

         public String persist(Details details){
             details.getUsername();
             details.getPassword();
             Query query = em.createNativeQuery("db.details.find(username= "+details.getUsername()+"& password= "+details.getPassword());

             em.persist(details);
             System.out.println("Sucessful!");
            return "persist";        
     }

EDIT : The problem seems to be with your configuration file. If you are using JPA then your configuration file should have below configuration
