Java中Json字符串转换为对象的方法(多层List集合)
借鉴自：http://www.jb51.net/article/91142.htm
在将json字符串转换成对象flightInfo时，当flightInfo对象中有List<flightClassInfo>类型的字段时，使用阿里巴巴的JSON.parse(jsonString, FlightInfo.class)时，其内部的list<flightClassInfo>没有转换成功，而是转换成HashMap结构。因此使用JSONObject对象;
1.maven依赖
<dependency> <groupId>net.sf.json-lib</groupId> <artifactId>json-lib</artifactId> <version>2.4</version> <classifier>jdk15</classifier> </dependency>
2.java代码
1 try{ 2 JSONObject jsonObject = JSONObject.fromObject(jsonFlight); 3 Map<String,Class> map = new HashMap<String,Class>(); 4 map.put("bingoClassInfoList", FlightClassInfo.class); 5 FlightInfo flightInfo = (FlightInfo) JSONObject.toBean(jsonObject, FlightInfo.class, map); 6 List<FlightInfo> flights = new ArrayList<FlightInfo>(); 7 flights.add(flightInfo); 8 filterCharterFlight(flights); 9 System.out.println(flights.toString()); 10 }catch (Exception e){ 11 e.printStackTrace(); 12 }
其中FlightInfo类如下：
1 import java.io.Serializable; 2 import java.util.List; 3 4 public class FlightInfo implements Serializable { 5 6 private static final long serialVersionUID = 8604216922911620556L; 7 /** 8 * 航班信息属性 9 */ 10 public String airways; 11 12 public String airwaysCn; 13 14 public String arrAirdrome; 15 16 public String arrCity; 17 18 public String arrCityCn; 19 20 public String arrDate; 21 22 public String arrTerminal; 23 24 public String arrTime; 25 26 public boolean asr; 27 28 public String carrier; 29 30 public String carrierCn; 31 32 public long childfee; 33 34 public List<FlightClassInfo> bingoClassInfoList; 35 。。。。。
FlightClassInfo类对象如下：
1 import java.io.Serializable; 2 import java.util.List; 3 4 public class FlightClassInfo implements Serializable { 5 6 private static final long serialVersionUID = 2932213372331900441L; 7 8 public String c; 9 10 public double agentFee; 11 12 public double agentFeeGo; 13 14 public long avItemTax; 15 16 public String basicCabinRef; 17 18 public long childOilTax; 19 20 public long childPrice; 21 22 public String childfarebasis; 23 24 public String classNo; 25 26 public String classNoCn; 27 。。。。。。
json字符串如下
