Question

List<String> Mylist是org.hibernate.collection.PersistentBag ...

并且我想删除这个我的列表...
我该怎么做？

QriteriaBuilder criteriaBuilder = em.getCriteriaBuilder();
CriteriaQuery<A_entity> criteriaQuery = criteriaBuilder.createQuery(A_entity.class);
criteriaQuery.from(A_entity.class);
Query query = em.createQuery(criteriaQuery);
List<A_entity> queryList = query.getResultList();
for (A_entity a:queryList)
{
   if(....)
   {
     List<String> Mylist = a.func();
     ???How delete Mylist????
   }
}

非常感谢!!

尝试一个一个地删除元素:

List<String> Mylist = a.getMyList();
em.getTransaction().begin();
for (String element:Mylist){
    em.remove(element);
}
em.getTransaction().commit();

解决方案(为我工作，感谢“Genzotto”):

List<String> Mylist = a.getMyList();
listStirng.clear();
em.getTransaction().begin();
     for (String str : Mylist) {
         em.merge(str);
     }
em.getTransaction().commit();
