json数据解析成java对象(国家气象局数据)

网友翻出来的国家气象局天气预报查询出来的数据是这样的。然后看的像JSON 然后感觉哪里不对 最后就把他当做JSON玩。。

找啊找 找到了一个工具 Gson 然后就 上代码吧

4.方法测试

import java.io.IOException;import org.json.JSONException;import com.google.gson.Gson;public class weatherinfoToJavaBean {public static void main(String[] args) throws IOException, JSONException {        String str=getDate.readContentFromGet();        Gson gson = new Gson();        weatherinfoList winfo=gson.fromJson(str, weatherinfoList.class);        System.out.println(winfo.getWeatherinfo().getCity());}}

5.输出截图
