我使用带有hibernate的条件API;
当我使用像[1]这样的entitymanager时，我得到以下异常
[1]
@PersistenceContext
private EntityManager em;
public void update(Tank entity) {
Tank item = em.getReference(Tank.class,entity.getId());
if (entity.getManufacturerId()!=null) {
item.setManufacturer(em.getReference(Manufacturer.class , entity.getManufacturerId()));
item.setManufacturerId(entity.getManufacturerId());
}
..
}
