Google App Engine에서 최대 절전 모드로 엔티티 relatinships를 관리하는 방법

Question

하나의 onetoMany 관계 코드 만 사용하면 정상적으로 작동합니다. 엔티티에서 1 @onetomany 관계가 더 이상 선언 될 때 org.hibernate.exception.SQLGrammarException : '필드 목록'에 'userregist0_.jdoDetachedState'알 수없는 열이 것을 관리 할 수있는 방법 내 엔티티 클래스는 package com.bullbeardevice입니다. .모델;

Answer 1

app-engine을 사용하면 최대 절전 모드가 필요하지 않습니다. 최대 절전 모드에서 사용하는 대부분의 JPA 주석은 기본적으로 app-engine에서 지원됩니다. JDO (javax.jdo)와 JPA (javax.persistence)를 섞어서는 안된다.
