Firebase @Exclude与Kotlin数据类 [英] Firebase @Exclude with kotlin data class

问题描述

我在Kotlin中有此数据类(示例):

I have this data class in Kotlin (example):

import com.google.firebase.database.Exclude

data class User(val name: String = "", @Exclude val age: Int = 0)

而且我不想将age属性保存在firebase中. @Exclude应该执行此操作，但是它不起作用，仍然可以保存年龄.

And I don't want to save the age property in firebase. @Exclude should do this but it does not work, age is still saved.

有没有解决方法?

推荐答案

在属性上放置@Exclude会针对其生成的字段，而不是其生成的get accesor方法.要执行后者，您需要在"Exclude"之前加上"get:"前缀.例如:

Placing @Exclude on a property targets its generated field and not its generated get accesor method. To do the latter you'll need to prefix "Exclude" with "get:". e.g.:

data class User(val name: String = "", @get:Exclude val age: Int = 0)
