无法删除或更新父行：外键约束失败（hibernate xml映射）

我想删除所有的组，其中一个用户是所有者，但它目前不起作用。我认为在映射User.hbm.xml或Group.hbm.xml的级别上缺少一些东西，但我不知道。错误为“无法删除或更新父行：外键约束失败（

sharedmap

groupe

，约束

请尝试将inverse=true添加到用户文件集名称privative中，并使用cascade=all“删除孤立文件”

当用户被删除时，它将删除组。另外，请特别注意在Hibernate中删除用户的方式：

删除用户之前必须刷新会话。

---

必须从所有活动会话和二级缓存中删除所有链接到用户的组。

需要理解的代码很多，请您将其缩减为所需的代码。我删除了部分代码，并在问题中添加了错误跟踪。这个答案几乎无法理解。“用户文件集名称”也有什么用“什么意思？
