琴音飘渺 2015-04-22 05:53:35

求解析下面这段JSON 红色是需要得到的值急求！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！用了不少方法可是总是有错求简单有效的方法最好是能够用代码来解释表示不要只给思路现在思路一大推

{
"RspMessage": {
"Body": {
"orderHeads": {
"com.qthd.deal.server.client.vo.OrderHead": [
{
"linkAddr": "成都市",

CalendarInfo 是什么

嘿嘿，给你个最简便的方法，你先对应数据格式把对象建好，比如像这样


public class PatientInfo {
	public String dischargeDate;
	public String returnvisitDate;
	public String doctorNote;
	public String id;
	public List<String> medicines; 
	public Doctor doctor;// 
}

这个对象里就有基本数据类型，也有list，还有一个doctor对象。然后用FastJSON这个jar里的JSONObject.parseObject方法可以直接解析成一个对象，该json解析jar包是目前公认较快的。

例子： {"calendar": {"calendarlist": [ {"calendar_id":"1705","title":"(\u4eb2\u5b50)ddssd","category_name":"\u9ed8\u8ba4\u5206\u7c7b","showtime":"1288927800","endshowtime":"1288931400","allDay":false}, {"calendar_id":"1706","title":"(\u65c5\u884c)","category_name":"\u9ed8\u8ba4\u5206\u7c7b","showtime":"1288933200","endshowtime":"1288936800","allDay":false} ] } } JSON转换 JSONObject jsonObject = new JSONObject(builder.toString()) .getJSONObject("calendar"); JSONArray jsonArray = jsonObject.getJSONArray("calendarlist"); for(int i=0;i<jsonArray.length();i++){ JSONObject jsonObject2 = (JSONObject)jsonArray.opt(i); CalendarInfo calendarInfo = new CalendarInfo(); calendarInfo.setCalendar_id(jsonObject2.getString("calendar_id")); calendarInfo.setTitle(jsonObject2.getString("title")); calendarInfo.setCategory_name(jsonObject2.getString("category_name")); calendarInfo.setShowtime(jsonObject2.getString("showtime")); calendarInfo.setEndtime(jsonObject2.getString("endshowtime")); calendarInfo.setAllDay(jsonObject2.getBoolean("allDay")); calendarInfos.add(calendarInfo); } []类型的是JSONArray ；{}类型的是JSONObject。不能一把转换，例子楼上有。你要是怕麻烦，也可以使用Gson，有实体对象就能直接转换，也很方便。猛戳这里！

是｛｝这种类型的就转成JSONObject，是[] 类型就转成 JSONArray，不会有错，除非有字段的key不确定经常变换。
