Can not commit bulk transaction on insert failure due to duplicate key error

Hibernate ORM
1

I use Spring + Hibernate + JPA

I need to insert the list of ORDER(maximum 60 or 70) . I do not want my processing to fail in case of duplicates.

Is it possible to do such bulk INSERT in single transaction, catch/suppress exception for duplicates, proceed with INSERT and commit the transaction? Or, is there no other way than transaction-per-INSERT pattern (or) merge (or) find the record based on Primary key and insert If no primarykey is found?

Currently, my transaction is always rolled back for DataIntegrityViolationException , no matter how I configure noRollbackFor attribute for my transaction ( Transactional annotation).

When 1 duplicate Record is inserted , it throws DataIntegrityVioalationException and while processing the next record it results

org.springframework.transaction.TransactionSystemException: Could not commit JPA transaction; nested exception is javax.persistence.RollbackException: Transaction marked as rollbackOnly

Here is the Unit of work :

for(Order order: OrderList) {
   // Insert order into ORDER table
        //If insert fails due to Duplicate key then no rollback and I follow steps 2 & 3. 
        //If insert fails due to any reason except duplicate key then rollback all the previous transactions
}

Here is my implemenation :

Service :

@Autowired
MyRepository repo;

@Transactional
@override
public void inserOrder(List<Order> orderList) {
  try {
       for(Order order: orderList) {
             repo.insertOrderDao(order);
        }
  } catch(all duplicate key exceptions like entityExist, persist, ConstraintVioaltion, DataIntegrity e) {
       // just log it and do nothing;
  } catch(Exception e) {
       e1.printStackTrace();
  }  
}

My Repositary :

@PersistentContext(unitNmae = "MY_SHCEMA")
EntityManager entityManager;

@Override
public void insertOrderDao(Order order) {
     entityManager.persist(order);
     entityManager.flush(); 
}
