天氣預報的介面 josn 進行企業級的解析
在以前 有一個天氣預報的介面,是json型別的,資料比較大,不會進行解析,功能沒有做出來,今天偶然的學習中,可以拿出來了
api返回的資料:
{ "date": "20180805", "message": "Success !", "status": 200, "city": "北京", "count": 1, "data": { "shidu": "66%", "pm25": 60, "pm10": 103, "quality": "輕度汙染", "wendu": "31", "ganmao": "兒童、老年人及心臟、呼吸系統疾病患者人群應減少長時間或高強度戶外鍛鍊", "yesterday": { "date": "04日星期六", "sunrise": "05:14", "high": "高溫 36.0℃", "low": "低溫 27.0℃", "sunset": "19:26", "aqi": 126, "fx": "南風", "fl": "<3級", "type": "晴", "notice": "願你擁有比陽光明媚的心情" }, "forecast": [ { "date": "05日星期日", "sunrise": "05:15", "high": "高溫 35.0℃", "low": "低溫 25.0℃", "sunset": "19:25", "aqi": 91, "fx": "東風", "fl": "<3級", "type": "雷陣雨", "notice": "帶好雨具，別在樹下躲雨" }, { "date": "06日星期一", "sunrise": "05:16", "high": "高溫 31.0℃", "low": "低溫 25.0℃", "sunset": "19:24", "aqi": 90, "fx": "東風", "fl": "<3級", "type": "雷陣雨", "notice": "帶好雨具，別在樹下躲雨" }, { "date": "07日星期二", "sunrise": "05:17", "high": "高溫 30.0℃", "low": "低溫 24.0℃", "sunset": "19:22", "aqi": 98, "fx": "東風", "fl": "<3級", "type": "雷陣雨", "notice": "帶好雨具，別在樹下躲雨" }, { "date": "08日星期三", "sunrise": "05:18", "high": "高溫 30.0℃", "low": "低溫 24.0℃", "sunset": "19:21", "aqi": 52, "fx": "東風", "fl": "<3級", "type": "雷陣雨", "notice": "帶好雨具，別在樹下躲雨" }, { "date": "09日星期四", "sunrise": "05:19", "high": "高溫 31.0℃", "low": "低溫 24.0℃", "sunset": "19:20", "aqi": 64, "fx": "南風", "fl": "<3級", "type": "小雨", "notice": "雨雖小，注意保暖別感冒" } ] } }
程式碼的實現weather
public class Weather { private String date; private String sunrise; private String high; private String low; private String sunset; private int aqi; private String fx; private String fl; private String type; private String notice;
public Weather(String date, String sunrise, String high, String low, String sunset, int aqi, String fx, String fl, String type, String notice) { this.date = date; this.sunrise = sunrise; this.high = high; this.low = low; this.sunset = sunset; this.aqi = aqi; this.fx = fx; this.fl = fl; this.type = type; this.notice = notice; }
public String getDate() { return date; }
public void setDate(String date) { this.date = date; }
public String getSunrise() { return sunrise; }
public void setSunrise(String sunrise) { this.sunrise = sunrise; }
public String getHigh() { return high; }
public void setHigh(String high) { this.high = high; }
public String getLow() { return low; }
public void setLow(String low) { this.low = low; }
public String getSunset() { return sunset; }
public void setSunset(String sunset) { this.sunset = sunset; }
public int getAqi() { return aqi; }
public void setAqi(int aqi) { this.aqi = aqi; }
public String getFx() { return fx; }
public void setFx(String fx) { this.fx = fx; }
public String getFl() { return fl; }
public void setFl(String fl) { this.fl = fl; }
public String getType() { return type; }
public void setType(String type) { this.type = type; }
public String getNotice() { return notice; }
public void setNotice(String notice) { this.notice = notice; } }
程式碼的實現;weathdata
public class WeatherData { @JSONField(ordinal = 1) private String shidu; @JSONField(ordinal = 2) private int pm25; @JSONField(ordinal = 3) private int pm10; @JSONField(ordinal = 4) private String quality; @JSONField(ordinal = 5) private String wendu; @JSONField(ordinal = 6) private String ganmao; @JSONField(ordinal = 7) private Weather yesterday; @JSONField(ordinal = 8) private List<Weather> forecast;
public String getShidu() { return shidu; }
public void setShidu(String shidu) { this.shidu = shidu; }
public int getPm25() { return pm25; }
public void setPm25(int pm25) { this.pm25 = pm25; }
public int getPm10() { return pm10; }
public void setPm10(int pm10) { this.pm10 = pm10; }
public String getQuality() { return quality; }
public void setQuality(String quality) { this.quality = quality; }
public String getWendu() { return wendu; }
public void setWendu(String wendu) { this.wendu = wendu; }
public String getGanmao() { return ganmao; }
public void setGanmao(String ganmao) { this.ganmao = ganmao; }
public Weather getYesterday() { return yesterday; }
public void setYesterday(Weather yesterday) { this.yesterday = yesterday; }
public List<Weather> getForecast() { return forecast; }
public void setForecast(List<Weather> forecast) { this.forecast = forecast; } }
使用的是三層結構 ---->servlet
@WebServlet("/weather") public class WeatherServlet extends HttpServlet { protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 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","高溫 36.0℃","低溫 27.0℃","19:26",126,"南風","<3級","晴","願你擁有比陽光明媚的心情"); Weather weather1 = new Weather("05日星期日","05:14","高溫 36.0℃","低溫 27.0℃","19:26",126,"南風","<3級","晴","願你擁有比陽光明媚的心情"); Weather weather2 = new Weather("06日星期一","05:14","高溫 36.0℃","低溫 27.0℃","19:26",126,"南風","<3級","晴","願你擁有比陽光明媚的心情"); Weather weather3 = new Weather("07日星期二","05:14","高溫 36.0℃","低溫 27.0℃","19:26",126,"南風","<3級","晴","願你擁有比陽光明媚的心情"); Weather weather4 = new Weather("08日星期三","05:14","高溫 36.0℃","低溫 27.0℃","19:26",126,"南風","<3級","晴","願你擁有比陽光明媚的心情"); Weather weather5 = new Weather("09日星期四","05:14","高溫 36.0℃","低溫 27.0℃","19:26",126,"南風","<3級","晴","願你擁有比陽光明媚的心情"); WeatherData weatherData = new WeatherData(); weatherData.setShidu("66%"); weatherData.setPm25(60); weatherData.setPm10(103); weatherData.setQuality("輕度汙染"); weatherData.setWendu("31"); weatherData.setGanmao("兒童、老年人及心臟、呼吸系統疾病患者人群應減少長時間或高強度戶外鍛鍊"); 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); } }
