Parse Json to Primative Array Kotlin

问题

Maybe this is simple, but I'm missing how to do this. I'm using GSON, kotlin, and retrofit

Data.json

{
  "array1":[1,2],
  "array2":[1,2]
}

DataObject.kt

data class DataObject(array1: List<Int>, array2: List<Int>)

The the above fails to deserialize the arrays.

回答1:

This is a running example:

data class DataObject(val array1: List<Int>, val array2: List<Int>)

fun main(args: Array<String>) {
    val json = """{"array1":[1,2],"array2":[1,2]}"""
    println(Gson().fromJson(json, DataObject::class.java))
    //DataObject(array1=[1, 2], array2=[1, 2])
}

I've only changed the arguments of DataObject to be val, which is required for data classes (var also works).
