Java Hibernate 4.3.11忽略级联错误

冬眠：4.3.11 Spring Boot JPA:1.3.3 使用JPA注释

Hibernate正在级联到我试图保存并试图删除孤立对象的一个对象中的列表。当注释上没有指定cascade并且cascade opphan默认为false时，有人能解释为什么它会尝试这样做吗？我已经尝试显式地将cascasde孤立项设置为false，结果相同。下面是与注释一起保存的类

编辑：为了进一步说明，保存时对象中的列表为空，但数据库中有子记录。hibernate似乎在持久化孤立删除，因为它在表上运行SQL delete以删除列表中不包含的子记录，即使未启用级联

hibernate似乎正试图处理departmentGroupQueueList以删除孤立项

编辑： 该应用程序正在使用Struts2 MVC框架。Department对象是由Struts在表单子委员会上创建的。下面是从表单save上运行的方法中剪下的一个片段。dao对象正在从Spring注入

public String update() {

    if(getModel().getParentId().getId() == null){
        getModel().setParentId(null);
    }

    setModel(departmentDao.update(getModel()));

    return "editResult";
}

传递给update（）的部门来自哪里？它是如何填充的？它使用Struts2框架，该框架通过表单的保存填充department对象。我将从Struts操作中粘贴代码，该操作将对象传递给dao。我仍在努力解决这个问题，并认为问题可能实际上存在于我的多个关联中。您需要加载和更新现有的持久性实例，即直接将传入数据绑定到从数据库加载的实例，或者将填充的实例中的值复制到持久性实例。

public String update() {

    if(getModel().getParentId().getId() == null){
        getModel().setParentId(null);
    }

    setModel(departmentDao.update(getModel()));

    return "editResult";
}
