Java中Json字符串直接轉換為對象的辦法(包含多層List聚集)。本站提示廣大學習愛好者:(Java中Json字符串直接轉換為對象的辦法(包含多層List聚集))文章只能為提供參考,不一定能成為您想要的結果。以下是Java中Json字符串直接轉換為對象的辦法(包含多層List聚集)正文
應用到的類:net.sf.json.JSONObject
應用JSON時,除要導入JSON網站下面下載的json-lib-2.2-jdk15.jar包以外,還必需有其它幾個依附包:commons-beanutils.jar,commons-httpclient.jar,commons-lang.jar,ezmorph.jar,morph-1.0.1.jar
上面是例子代碼:
// JSON轉換 JSONObject jsonObj = JSONObject.fromObject(jsonStrBody); Map<String, Class> classMap = new HashMap<String, Class>(); classMap.put("results", WeatherBean_Baidu_City.class); classMap.put("index", WeatherBean_Baidu_City_Index.class); classMap.put("weather_data", WeatherBean_Baidu_City_Weatherdata.class); // 將JSON轉換成WeatherBean_Baidu WeatherBean_Baidu weather = (WeatherBean_Baidu) JSONObject.toBean(jsonObj, WeatherBean_Baidu.class, classMap); System.out.println(weather.getResults());
應用到的幾個JAVA類代碼:
package com.lenovo.conference.entity.vo; import java.io.Serializable; import java.util.List; /** * 氣象Bean * * @author SHANHY * */ @SuppressWarnings("serial") public class WeatherBean_Baidu implements Serializable { private String error;//毛病號 private String status;//狀況值 private String date;//日期 private List<WeatherBean_Baidu_City> results;//城市氣象預告聚集(由於一次可以查詢多個城市) public WeatherBean_Baidu() { super(); } public String getError() { return error; } public void setError(String error) { this.error = error; } public String getStatus() { return status; } public void setStatus(String status) { this.status = status; } public String getDate() { return date; } public void setDate(String date) { this.date = date; } public List<WeatherBean_Baidu_City> getResults() { return results; } public void setResults(List<WeatherBean_Baidu_City> results) { this.results = results; } }

package com.lenovo.conference.entity.vo; import java.io.Serializable; /** * 氣象Bean * * @author SHANHY * */ @SuppressWarnings("serial") public class WeatherBean_Baidu_City_Weatherdata implements Serializable { private String date;// 日期 private String dayPictureUrl;// 日間的氣象圖片 private String nightPictureUrl;// 早晨的氣象圖片 private String weather;// 氣象 private String wind;// 風向 private String temperature;// 溫度 public WeatherBean_Baidu_City_Weatherdata() { super(); } public String getDate() { return date; } public void setDate(String date) { this.date = date; } public String getDayPictureUrl() { return dayPictureUrl; } public void setDayPictureUrl(String dayPictureUrl) { this.dayPictureUrl = dayPictureUrl; } public String getNightPictureUrl() { return nightPictureUrl; } public void setNightPictureUrl(String nightPictureUrl) { this.nightPictureUrl = nightPictureUrl; } public String getWeather() { return weather; } public void setWeather(String weather) { this.weather = weather; } public String getWind() { return wind; } public void setWind(String wind) { this.wind = wind; } public String getTemperature() { return temperature; } public void setTemperature(String temperature) { this.temperature = temperature; } }
package com.lenovo.conference.entity.vo; import java.io.Serializable; /** * 氣象Bean * * @author SHANHY * */ @SuppressWarnings("serial") public class WeatherBean_Baidu_City_Index implements Serializable { private String title;//題目 private String zs;//溫馨度 private String tipt;//指數簡述 private String des;//指數概述 public WeatherBean_Baidu_City_Index() { super(); } public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } public String getZs() { return zs; } public void setZs(String zs) { this.zs = zs; } public String getTipt() { return tipt; } public void setTipt(String tipt) { this.tipt = tipt; } public String getDes() { return des; } public void setDes(String des) { this.des = des; } }
