android - 使用 Retrofit 如何在没有对象解析的情况下解析 JSONArray？

Question

我正在解析以下 Json 格式:

{
msg: "success",
status_code: 200,
data: [
{
....
}  ]
}

我在以下对象中使用 Retorfit2 解析它:

public class Model {
    @SerializedName("status_code")
    int statusCode;
    @SerializedName("msg")
    private String statusMsg;
    @SerializedName("data")
    private JSONArray data;

}

我想将“数据”解析为 JSONArray 而不是特定的模型类型，而不管其内部对象结构如何。但是它给出了以下异常，问题是什么？

看看下面的代码行。

`

public class Model {
    @SerializedName("status_code")
    int statusCode;
    @SerializedName("msg")
    private String statusMsg;
    @SerializedName("data")
    private **ArrayList<JSONObject>** data;

}
