Java - Gson解析嵌套在嵌套中

Question

我必须与API进行交互,响应格式(从我读过的内容)看起来结构很差.我发现谷歌小组在这里回复了一个类似的问题,但我在实现一个Response类来处理Gson.fromJson时遇到了麻烦.有没有一个例子我错过了那里？

{

"response":{
    "reference": 1023, 
    "data":{
        "user":{
            "id":"210",
            "firstName":"john",
            "lastName":"smith",
            "email":"pocahontas@gmail.com",
            "phone":"",
            "linkedid":{
                "id":"238"
            }
        }
    }
}

}

JSON对象{}可以由一个Map<String, Object>或Javabean类表示.这是一个使用Javabean的示例.

public class ResponseData {
    private Response response;
    // +getter+setter

    public static class Response {
        private int reference;
        private Data data;
        // +getters+setters
    }

    public static class Data {
        private User user;
        // +getter+setter
    }

    public static class User {
        private String id;
        private String firstName; 
        private String lastName;
        private String email;
        private String phone;
        private Linkedid linkedid;
        // +getters+setters
    }

    public static class Linkedid {
        private String id;
        // +getter+setter
    }
}

使用方法如下:

ResponseData responseData = new Gson().fromJson(json, ResponseData.class);
