Spring Data JPA, how to one attribute map to two columns?

Suppose I have "Account" entity class, and "Transaction" entity class. In table, detail is:

transfer_id, account_from_id, account_to_id, money

565 1 2 12

566 3 1 15

So what annotation or how to code Account entity class, so when I get account.getTransactions, for account_id = 1, it will has 2 transactions? (because both transfer entity involves account id = 1)

public class Account {
     // ...
     //TODO: How should I do here? Use which annotation or how to do?
     private Set<Transfer> transfers;
