guice, jpa 및 최대 절전 모드를 결합하려고합니다. 하이버 네이트의 초기화는 매핑 된 클래스 쓰루 DAO에 액세스하려고 시도 할 때까지 좋은 것처럼 보입니다. 나는 모든 도움 요청을 발견했다. 그러나 나의 문제는 (지금은) "커스텀 클래스"(적어도 나는 그렇게 생각하지 않는다)이다.최대 절전 모드 : 지속성을 찾을 수 없습니다 : java.math.BigDecimal
모두 함께 특별하지 않습니다. 나는 나의 클래스와 그 클래스 중 하나에 대한 기본 (persist, findById, remove) DAO를 정의하는 persistence.xml을 얻었다. 내가
final LayerDao dao = this.layerDaoProvider.get();
final Layer layer = dao.findById(386L); //Tried with BigDecimal, Long
좋아하는 DAO와 데이터베이스에 액세스하려고하면
public abstract class AbstractDao<E, K> implements Dao<E, K> {
@Inject
private EntityManager manager;
private final Class<E> entityClass;
@SuppressWarnings("unchecked")
public AbstractDao() {
final ParameterizedType genericSuperclass = (ParameterizedType) this.getClass().getGenericSuperclass();
this.entityClass = (Class<E>) genericSuperclass.getActualTypeArguments()[1];
}
@Override
public void persist(final E entity) {
this.manager.persist(entity);
}
@Override
public void remove(final E entity) {
this.manager.remove(entity);
}
@Override
public E findById(final K id) {
return this.manager.find(this.entityClass, id);
}
}
나는 다음과 같은 오류를 (내가 java.lang.Long의과 동일한 오류가) 얻을 :

일부 Java 코어 클래스에는 문제가 없을 것으로 예상됩니다.

나는 무엇을 놓치고? 나를 도울 수있는 정보가 더 필요하십니까?
