在以前 有一个天气预报的接口,是json类型的,数据比较大,不会进行解析,功能没有做出来,今天偶然的学习中,可以拿出来了

api返回的数据:

使用的是三层结构    ---->servlet

@WebServlet("/weather")  
public class WeatherServlet extends HttpServlet \{

        doGet(request, response);  
    \}

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException \{  
        response.setContentType("text/html;charset=utf-8");  
        Weather weather = new Weather("04日星期六","05:14","高温 36.0℃","低温 27.0℃","19:26",126,"南风","<3级","晴","愿你拥有比阳光明媚的心情");  
        Weather weather1 = new Weather("05日星期日","05:14","高温 36.0℃","低温 27.0℃","19:26",126,"南风","<3级","晴","愿你拥有比阳光明媚的心情");  
        Weather weather2 = new Weather("06日星期一","05:14","高温 36.0℃","低温 27.0℃","19:26",126,"南风","<3级","晴","愿你拥有比阳光明媚的心情");  
        Weather weather3 = new Weather("07日星期二","05:14","高温 36.0℃","低温 27.0℃","19:26",126,"南风","<3级","晴","愿你拥有比阳光明媚的心情");  
        Weather weather4 = new Weather("08日星期三","05:14","高温 36.0℃","低温 27.0℃","19:26",126,"南风","<3级","晴","愿你拥有比阳光明媚的心情");

        WeatherData weatherData = new WeatherData();  
        weatherData.setShidu("66%");  
        weatherData.setPm25(60);  
        weatherData.setPm10(103);  
        weatherData.setQuality("轻度污染");  
        weatherData.setWendu("31");  
        weatherData.setGanmao("儿童、老年人及心脏、呼吸系统疾病患者人群应减少长时间或高强度户外锻炼");  
        weatherData.setYesterday(weather);  
        List<Weather> list = new ArrayList<>();  
        list.add(weather1);  
        list.add(weather2);  
        list.add(weather3);  
        list.add(weather4);  
        list.add(weather5);  
        weatherData.setForecast(list);

Map<String,Object> map = new HashMap<>();  
        map.put("data",weatherData);  
        String jsonString = JSON.toJSONString(map);  
        response.getWriter().print(jsonString);  
    \}  
\}
