不，Kotlin数据类不会隐式实现此接口。从这个例子中可以看出：

import java.io.Serializable

data class Foo(val bar: String)

fun acceptsSerializable(s: Serializable) { }

fun main(args: Array<String>) {
    val f: Foo = Foo("baz")
    
    // The following line produces the compiler error:
    // Type mismatch: inferred type is Foo but Serializable was expected
    acceptsSerializable(f)
}

我不得不在类的末尾添加: Serializable来使其可序列化。就像这样

class SizeVariantModel (val price: Double, val discountedPrice: Double?) : Serializable
class ColorVariantModel (val name: String, val colorCode: String) : Serializable

我还必须导入Serializable

import java.io.Serializable
