休眠:如何删除在ManyToOne中不再引用的实体? [英] Hibernate: How to remove an entity to which none refers to anymore in ManyToOne?

问题描述

我有两个实体，我们称它们为A和B，它们具有到另一个实体(例如C)的ManyToOne映射.

I have two entities, lets call them A and B, which have a ManyToOne mapping to another entity, say C

所以我通常有这样的东西:

So I typically have something like this:

a1-> c

a2-> c

b1-> c

很多A和B指向同一个C.

Lots of A's and B's pointing to the same C.

当我删除最后一个a和b时，如何让Hibernate删除c?

How do I get Hibernate to remove c when I remove the last a and b?

推荐答案

似乎JPA/Hibernate不支持此功能.这真的很糟糕.

It seems that JPA/Hibernate does not support this. Which is really bad.
