Question

我正在解析以下Json格式：

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

我在后面的对象中使用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'data'解析为JSONArray而不是特定的Model类型，而不管它的内部对象结构如何。但它给出了以下例外，问题是什么？

查看以下代码行。

`

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

}

使用Retrofit如何在没有对象解析的情况下解析JSONArray？
