休眠：4.3.11 Spring Boot JPA：1.3.3 使用JPA注释

Hibernate正在我尝试保存并试图删除孤儿的其中一个对象中级联到List。任何人都可以解释为什么它会在注释中没有指定级联时尝试这样做，而cascade-oprphan默认为false？我试图用相同的结果明确地将cascasde-orphan设置为false。下面是使用注释保存的类。

编辑：为了进一步说明，对象中的List在保存时为空，但db中有子记录。似乎hibernate持续使用孤立删除，因为它在表上运行SQL删除以删除未包含在List中的子记录，即使未启用级联也是如此。

hibernate似乎试图处理孤儿删除的departmentGroupQueueList。

以下是DAO中保存对象的代码

return Redirect::to($url);

编辑：该应用程序使用Struts2框架进行MVC。 Struts在表单submmission上创建了Department对象。下面是从表单上运行的方法剪切保存。 dao对象是从Spring注入的
