您好我正在使用 Hibernate 并尝试从我的数据库(Oracle 11g)中删除一些信息我有这样的代码:
Session session = sessionFactory.getCurrentSession();
session.beginTransaction();
Query query = session.createQuery(DELETE_NEWS_BY_ID);
query.setParameterList(ID, Arrays.asList(idList));
query.executeUpdate();
session.getTransaction().commit();
和 DELETE_NEWS_BY_ID 字段如下所示:
private static final String DELETE_NEWS_BY_ID = "delete from News where id IN (:idList)";
当我尝试处理此代码时,IDE 给了我这个:
java.lang.ClassCastException: [I cannot be cast to java.lang.Integer

我不知道什么是我I cannot be cast to java.lang.Integer

请帮忙
