我如何使用Gson将其解析为Java？

Answer 1

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import com.google.gson.Gson;

public class GsonDemo {
    public static void main(String[] args) { 
    Gson gson = new Gson(); 
    try { 
        String json = "" ; // your json string
        //convert the json string to object
        YourObject obj = gson.fromJson(json, YourObject.class);  
    } catch (IOException e) {
        e.printStackTrace();
    } 
    }
}

Answer 2

public class Metadata{
    public String uri;
    public String Query;
    public String ID;
    public String Title;
    public String Description;
    public String DisplayUrl;
    public String Url;
}

public class ResponseResults{
    public MetadataContainer[] results;
    public String __next; 
}


public class MetadataContainer{
    public Metadata __metadata;
}


public class ResponseData{
    public ResponseResults d;
}

String json; //Your json response
ResponseData myD = new Gson().fromJson(json, ResponseData.class);
