嗨，我是阔叶的新手，并试图理解它，因此在浏览阔叶商务的代码时，我在实体字段上找到了 @AdminPresentation 以及许多与 @Admin 相关的内容，例如 @AdminPresentationAdornedTargetCollection、@AdminPresentationCollection等相关注解所以请解释一下这些注解的作用是什么或者任何引用链接对理解这些注解非常有帮助

最佳答案
@Admin...注释的目的是提供一种在管理中呈现类字段的简单方法。
例如，FriendlyName 将指定在管理员中呈现时为所述字段显示的名称。如果我要扩展 Product 并添加一个新字段 ProductOrigin ，例如
@AdminPresentation(friendlyName = "Product Origin")
public String productOrigin;
它将在管理员中显示为名称为“产品来源”的文本框，允许我们将数据输入到新字段中，该字段将保留到数据库中。所有这些都带有一个简单的注释。
以类似的方式，tab 将指定在哪个选项卡中显示字段，而 tabOrder 指示以什么顺序显示选项卡。请注意，如果您为以前不存在的选项卡提供新名称，则会创建一个新选项卡。如果您查看 AdminPresentation.java，您会发现源代码有详细的文档记录，并且您可以了解每个参数将提供什么。
@AdminPresentation 是最简单的情况，因为它用于呈现未链接到其他类的字段。您在提供的类中看到的其他内容用于呈现更复杂的关系，例如显示列表父类别 (@ AdminPresentationAdornedTargetCollection)。
希望这有帮助! 杰瑞
