json - 从Kotlin的子类获取SerializedName参数

Question

我正在尝试解析主要是这样构造的API响应:

{
    "ApiFunc1":{
        "SomeData1":"SomeValue1",
        "SomeData2":"SomeValue2",
        "SomeData3":"SomeValue3"
    }
}


{
    "ApiFunc2":{
        "SomeData4":"SomeValue4",
        "SomeData5":"SomeValue5",
        "SomeData6":"SomeValue6"
    }
}
.
.
.

我创建了一个基类，如下所示:

class Model_BaseResponse<TResponse> : Serializable {

    @SerializedName("ErrorMessage")
    var errorMessage: String? = null

    @SerializedName("value")
    var data: TResponse? = null

}

每个ApiFunc返回不同的数据。我想创建一个基类，可以在子类中设置data: TResponse的@SerializedName(“ApiFunc1”)或@SerializedName(“ApiFunc2”)。有什么办法吗？我会定期进行定义

@SerializedName("value")
var data: TResponse? = null

在每个 child 类。只是对此感到好奇。预先感谢您的任何想法。

像SerializedData这样的注释要求其参数为编译时常量。看看Kotlin中的“编译时常数”意味着什么:

Properties the value of which is known at compile time can be marked as compile time constants using the const modifier. Such properties need to fulfil the following requirements:

• Top-level or member of an object
• Initialized with a value of type String or a primitive type
• No custom getter

Such properties can be used in annotations:

const val SUBSYSTEM_DEPRECATED: String = "This subsystem is deprecated"

@Deprecated(SUBSYSTEM_DEPRECATED) fun foo() { ... }

我相信您的用例不能满足“对象的顶级或成员”的第一个要求。
