你好，我正在尝试使用Annance和一些图像之间的oneToMany关系上传文件；因此，一个注释可以包含0个或多个图像，并且一个图像仍然附加到一个注释。我认为我的实体一切都可以，但我在提交表格时遇到了这个错误。

我在提交表格时有以下错误：
属性"images"和其中一个方法"addImag（）"/"removeImag（，"setImages（）"、"images（）"，"__set（）"或"__call（）"存在并且具有类"MDB''AnnanceBundle''Entity''Annance"中的公共访问。
我不明白为什么这些getter存在于我的实体中。有人有主意吗？
感谢
这个错误是逻辑错误。只需使用集合字段类型即可解决问题
