@Configuration
public class MyConfig {
  @Bean
  public AccountRepository accountRepository() {
    return new JdbcAccountRepository();
  }
  @Bean
  public TransferService transferService() {
    TransferServiceImpl service = new TransferServiceImpl();
    service.setAccountRepository(accountRepository());
    return service;
  }
  @Bean
  public AccountService accountService() {
    return new AccountServiceImpl(accountRepository());
  }
}

Based on the default Spring behavior, how many AccountRepository beans will be instantiated?
