android - java.lang.IllegalArgumentException : Platform class java. time.LocalDateTime(没有注释)需要显式 JsonAdapter

将minsdk更改为26并使用带有android 9的模拟器后
出现以下错误

在我的模型中，我有一个类 UsersData，其中包含 LocalDateTime 的属性birthDay 类型，问题就在这里，我该如何解决

   data class UsersData (
        val id: kotlin.String? = null,
        val firstName: kotlin.String? = null,
        val lastName: kotlin.String? = null,
        val email: kotlin.String? = null,
        val phone: kotlin.String? = null,
        val image: kotlin.String? = null,
        val birthDay: java.time.LocalDateTime? = null,

    ) 

以下代码是适配器的类:

class LocalDateTimeAdapter : JsonAdapter<LocalDateTime>(){
    override fun toJson(writer: JsonWriter, value: LocalDateTime?) {
        value?.let { writer?.value(it.format(formatter)) }

    }

    override fun fromJson(reader: JsonReader): LocalDateTime? {
        return if (reader.peek() != JsonReader.Token.NULL) {
            fromNonNullString(reader.nextString())
        } else {
            reader.nextNull<Any>()
            null
        }    }
    private val formatter = DateTimeFormatter.ISO_LOCAL_DATE
    private fun fromNonNullString(nextString: String) : LocalDateTime = LocalDateTime.parse(nextString, formatter)

  }

以下代码是 Serializer 对象:

    import com.squareup.moshi.Moshi
    import com.squareup.moshi.adapters.Rfc3339DateJsonAdapter
    import java.util.*

 object Serializer {
    @JvmStatic
    val moshi: Moshi = Moshi.Builder()
            .add(com.squareup.moshi.kotlin.reflect.KotlinJsonAdapterFactory())
            .add(LocalDateTime::class.java, LocalDateTimeAdapter().nullSafe())
            .build()
}

添加自定义适配器后，出现新错误如下:

java.time.format.DateTimeParseException: Text '2019-09-16T09:00:00Z' could not be parsed, unparsed text found at index 10

Answer 1

您要么需要 Moshi 的明确 LocalDateTime 适配器，要么可以更改 birthDay成为 Date实例。

编辑:要解决更新代码的问题:

ISO_LOCAL_DATE 不支持日期和时间。您需要 ISO_LOCAL_DATE_TIME
