B扩展A和C扩展B.
让我们把名字放在这些上，这样我们就能更好地理解。
人A, B, and C扩展HumanBeing C延伸哺乳动物B
但是我也有一些类，比如A，它直接扩展了Mammal而没有扩展Person（似乎合法......我猜）。
Person扩展Cow的唯一原因是因为在某些时候，在某个其他实体中，我需要一个链接到HumanBeing的属性（由HumanBeing继承，但也是其他类如Person或FanOfJustinBieber）。
实际上，PrometheusMovieScriptWriter实体只是一个链接表，在我的梦想世界中它应该是：
HumanBeing，Person或FanOfJustinBieber）没有任何继承，PrometheusMovieScriptWriter直接延伸Person，juste就像Mammal。
但是我找不到告诉Doctrine的方法，我的班级Cow需要一个鉴别器，并且需要有一个指向HumanBeing，Person和{{1}的属性而且，如果他们不再共享一个共同的扩展类（除了来自FanOfJustinBieber，但由于有很多类扩展PrometheusMovieScriptWriter，我想我不能使用这个）。 / p>
这是我想象的方案：
Mammal
Mammal
Person,Cow,FanOfJustinBieber -> Mammal
我很难找到HumanBeing类的声明，特别是Doctrine注释。
对于HumanBeing: {id, linked_id (Person, ...), discriminator}，这似乎很简单（在SomeOtherEntity: {id, someAttribute, HumanBeing}之上Person）; @MappedSuperClass()（Mammal）更容易。
非常感谢任何帮助！
谢谢：）
