symfony2，doctrine2，类继承

Question

我在学说和symfony上玩了一点，我遇到了这个模型的问题。 我设置了一个基类（实体），然后是一个子类（实体），到目前为止，一切顺利，之后我想在我的表中添加更多字段，我使用了doctrine：generate：entities BundleName。这就是问题所在。如果我没有将变量从基类设置为受保护的symfony / doctrine说它无法访问该变量，但如果我将其设置为protected并再次生成实体，则会在我的子类中为基类创建受保护变量的getter和setter。我发现它很奇怪，所以我用谷歌搜索了一点，但我只发现了一个关于这个问题的话题并没有得到答案。 Base Class设置了注释MappedSuperclass但是..没有对它产生任何影响。

Answer 1

那么问题是什么？命令为什么这样做？或者在这种情况下如何使用它？

doctrine：generate：实体从它的映射生成实体类。映射可以用不同的格式描述，PHP注释只是其中之一（与xml和yml一起）。我认为逻辑以这种方式工作 - 首先从注释映射创建，然后从映射（无论如何描述此映射，如果属性是否继承），生成一个类。

所以不要担心，删除不必要的代码并继续前进。这只是节省一些时间的工具。
