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
try{
JSONObject jsonObject = JSONObject.fromObject(jsonFlight);
Map<String,Class> map = new HashMap<String,Class>();
map.put("bingoClassInfoList", FlightClassInfo.class);
FlightInfo flightInfo = (FlightInfo) JSONObject.toBean(jsonObject, FlightInfo.class, map);
List<FlightInfo> flights = new ArrayList<FlightInfo>();
flights.add(flightInfo);
filterCharterFlight(flights);
System.out.println(flights.toString());
}catch (Exception e){
e.printStackTrace();
}
其中FlightInfo类如下：
import java.io.Serializable;
import java.util.List; public class FlightInfo implements Serializable { private static final long serialVersionUID = 8604216922911620556L;
/**
* 航班信息属性
*/
public String airways; public String airwaysCn; public String arrAirdrome; public String arrCity; public String arrCityCn; public String arrDate; public String arrTerminal; public String arrTime; public boolean asr; public String carrier; public String carrierCn; public long childfee; public List<FlightClassInfo> bingoClassInfoList;
。。。。。
FlightClassInfo类对象如下：
import java.io.Serializable;
import java.util.List; public class FlightClassInfo implements Serializable { private static final long serialVersionUID = 2932213372331900441L; public String c; public double agentFee; public double agentFeeGo; public long avItemTax; public String basicCabinRef; public long childOilTax; public long childPrice; public String childfarebasis; public String classNo; public String classNoCn;
。。。。。。
json字符串如下
String jsonFlight = "{\n" +
