내 조직은 @Cache d입니다. 괜찮습니다.Memcache를 치지 않고 저장 목표로 지정
하지만 cron 작업의 경우 I 은이 아니므로 Memcache를 만지려면 ofy().save.entities()으로 지정하십시오. 그 이유는 수천 개의 객체를 저장하기 때문에 검색을 위해 뜨겁게 사용할 필요가 없기 때문입니다.

그래서, 내 질문은, 내가 어떻게 저장합니까 또한
, 나는 같은 이상한 예외를 점점 계속 Memcache를 치지 않고 Objectify를 사용합니까?
그리고/또는 이러한 예외가 발생하지 않게하려면 어떻게해야합니까?
ofy().cache(false).save()...
