질문: 배치공부하는데 id가1인사람한테 결제내역을 2분마다 추가해주는건데 한번 들어갈때 똑같은값이 무제한으로 계속들어가는 오류가 생기네요.. spring batch 장인있으시면 도와주세요,,

@Bean
public ItemReader<User> reader() {
  return ()-> userService.findById(1L);
}

@Bean
public ItemProcessor<User, Payment> processor() {
  return user -> {
    ...
    return payment;
  };
}

@Bean
public ItemWriter<Payment> writer() {
  return payments -> {
    log.info("{}",payments.size());
    ...
  };
}


@Bean
public Step myStep(ItemReader<User> reader, ItemProcessor<User, Payment> processor, ItemWriter<Payment> writer) {
  return ...
}

@Bean
public Job myJob(Step myStep) {
  return ...
}
