Java UnsupportedOperationException:删除子实体时

情景： 父类与子类有一对一和一对一的关系。 我想删除与父对象关联的所有子对象，但不删除父对象。并将新的子对象设置为父对象

为此，我在关系映射中使用orphaneremovation=true。 在代码中，我这样做：

parent.getChildCollection().clear();
parent.setChildCollection(new ChildCollection());

但我得到了以下例外：

    java.lang.UnsupportedOperationException: null

请建议。

堆栈跟踪提示错误的不同位置：仅限SetRollback。您发布的两行都不能生成对setRollbackOnly的调用。你确定原因吗？如果你发布完整的方法会更好。stackTrace指示代码的其他状态，如kostja@Amogh当前位置编辑，请看一看。我不认为这两行给你带来麻烦。你能从ImportJournalDaoBean.java发布方法findByFileName吗？一个cascade=all delete orphan的集合不再被引用了。问题是：我使用了list.add而不是setChildren，它工作得很好。
