java.lang.IllegalArgumentException：平台类 java.time.LocalDateTime （没有注释）需要显式 JsonAdapter

Question

在以下网址中参考我的问题：\n将 minsdk 更改为 26 并使用带有 android 9 的模拟器\n出现以下错误

\n\n

在我的模型中，我有一个 UsersData 类，其中包含 LocalDateTime 的属性birthDay 类型，问题是我该如何解决它

\n\n

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

\n\n

以下代码是适配器的类：

\n\n

class LocalDateTimeAdapter : JsonAdapter<LocalDateTime>(){\n    override fun toJson(writer: JsonWriter, value: LocalDateTime?) {\n        value?.let { writer?.value(it.format(formatter)) }\n\n    }\n\n    override fun fromJson(reader: JsonReader): LocalDateTime? {\n        return if (reader.peek() != JsonReader.Token.NULL) {\n            fromNonNullString(reader.nextString())\n        } else {\n            reader.nextNull<Any>()\n            null\n        }    }\n    private val formatter = DateTimeFormatter.ISO_LOCAL_DATE\n    private fun fromNonNullString(nextString: String) : LocalDateTime = LocalDateTime.parse(nextString, formatter)\n\n  }\n

\n\n

下面的代码是Serializer对象：

\n\n

    import com.squareup.moshi.Moshi\n    import com.squareup.moshi.adapters.Rfc3339DateJsonAdapter\n    import java.util.*\n\n object Serializer {\n    @JvmStatic\n    val moshi: Moshi = Moshi.Builder()\n            .add(com.squareup.moshi.kotlin.reflect.KotlinJsonAdapterFactory())\n            .add(LocalDateTime::class.java, LocalDateTimeAdapter().nullSafe())\n            .build()\n}\n

\n\n

添加自定义适配器后，出现新错误，如下所示：

\n\n

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

Answer 1

您要么需要 Moshi 的显式 LocalDateTime 适配器，要么可以更改birthDay为Date实例。

编辑：要使用更新的代码解决问题：：

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