没有叫Kotlin Moshi适配器

Question

我正在尝试在Kotlin中编写一个Moshi适配器，它将根据整数值创建枚举，如果遇到不支持的值，也会默认为特定的枚举值。

永远不会调用我的适配器，这会导致默认的枚举适配器因包含的堆栈跟踪而失败。

跟踪代码显示@ToJson注释以某种方式不存在，因此适配器isn't added when it should be。

声明适配器

enum class Status {
    IDLE,
    IN_PROGRESS,
    FAILED,
    SUCCESS,
    UNKNOWN;

    companion object {
        private val map = Status.values().associateBy(Status::ordinal);
        fun fromInt(type: Int?): Status {
            var ret = map[type]
            if (ret == null) {
                ret = UNKNOWN
            }
            return ret
        }

    }

    class Adapter {
        @ToJson
        fun toJson(status: Status): Int {
            return status.ordinal
        }

        @FromJson
        fun fromJson(value: Int): Status {
            return fromInt(value)
        }
    }
}

建立莫希

@Provides
@Singleton
fun provideMoshi(): Moshi {
    return Moshi.Builder()
            .add(Status.Adapter())
            .add(KotlinJsonAdapterFactory())
            .build()
}
